*/
extern uint64_t android_getCpuFeatures(void);
/* The list of feature flags for ANDROID_CPU_FAMILY_ARM that can be
* recognized by the library (see note below for 64-bit ARM). Value details
* are:
*
* VFPv2:
* CPU supports the VFPv2 instruction set. Many, but not all, ARMv6 CPUs
* support these instructions. VFPv2 is a subset of VFPv3 so this will
* be set whenever VFPv3 is set too.
*
* ARMv7:
* CPU supports the ARMv7-A basic instruction set.
* This feature is mandated by the 'armeabi-v7a' ABI.
*
* VFPv3:
* CPU supports the VFPv3-D16 instruction set, providing hardware FPU
* support for single and double precision floating point registers.
* Note that only 16 FPU registers are available by default, unless
* the D32 bit is set too. This feature is also mandated by the
* 'armeabi-v7a' ABI.
*
* VFP_D32:
* CPU VFP optional extension that provides 32 FPU registers,
* instead of 16. Note that ARM mandates this feature is the 'NEON'
* feature is implemented by the CPU.
*
* NEON:
* CPU FPU supports "ARM Advanced SIMD" instructions, also known as
* NEON. Note that this mandates the VFP_D32 feature as well, per the
* ARM Architecture specification.
*
* VFP_FP16:
* Half-width floating precision VFP extension. If set, the CPU
* supports instructions to perform floating-point operations on
* 16-bit registers. This is part of the VFPv4 specification, but
* not mandated by any Android ABI.
*
* VFP_FMA:
* Fused multiply-accumulate VFP instructions extension. Also part of
* the VFPv4 specification, but not mandated by any Android ABI.
*
* NEON_FMA:
* Fused multiply-accumulate NEON instructions extension. Optional
* extension from the VFPv4 specification, but not mandated by any
* Android ABI.
*
* IDIV_ARM:
* Integer division available in ARM mode. Only available
* on recent CPUs (e.g. Cortex-A15).
*
* IDIV_THUMB2:
* Integer division available in Thumb-2 mode. Only available
* on recent CPUs (e.g. Cortex-A15).
*
* iWMMXt:
* Optional extension that adds MMX registers and operations to an
* ARM CPU. This is only available on a few XScale-based CPU designs
* sold by Marvell. Pretty rare in practice.
*
* AES:
* CPU supports AES instructions. These instructions are only
* available for 32-bit applications running on ARMv8 CPU.
*
* CRC32:
* CPU supports CRC32 instructions. These instructions are only
* available for 32-bit applications running on ARMv8 CPU.
*
* SHA2:
* CPU supports SHA2 instructions. These instructions are only
* available for 32-bit applications running on ARMv8 CPU.
*
* SHA1:
* CPU supports SHA1 instructions. These instructions are only
* available for 32-bit applications running on ARMv8 CPU.
*
* PMULL:
* CPU supports 64-bit PMULL and PMULL2 instructions. These
* instructions are only available for 32-bit applications
* running on ARMv8 CPU.
*
* If you want to tell the compiler to generate code that targets one of
* the feature set above, you should probably use one of the following
* flags (for more details, see technical note at the end of this file):
*
* -mfpu=vfp
* -mfpu=vfpv2
* These are equivalent and tell GCC to use VFPv2 instructions for
* floating-point operations. Use this if you want your code to
* run on *some* ARMv6 devices, and any ARMv7-A device supported
* by Android.
*
* Generated code requires VFPv2 feature.
*
* -mfpu=vfpv3-d16
* Tell GCC to use VFPv3 instructions (using only 16 FPU registers).
* This should be generic code that runs on any CPU that supports the
* 'armeabi-v7a' Android ABI. Note that no ARMv6 CPU supports this.
*
* Generated code requires VFPv3 feature.
*
* -mfpu=vfpv3
* Tell GCC to use VFPv3 instructions with 32 FPU registers.
* Generated code requires VFPv3|VFP_D32 features.
*
* -mfpu=neon
* Tell GCC to use VFPv3 instructions with 32 FPU registers, and
* also support NEON intrinsics (see <arm_neon.h>).
* Generated code requires VFPv3|VFP_D32|NEON features.
*
* -mfpu=vfpv4-d16
* Generated code requires VFPv3|VFP_FP16|VFP_FMA features.
*
* -mfpu=vfpv4
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32 features.
*
* -mfpu=neon-vfpv4
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|NEON|NEON_FMA
* features.
*
* -mcpu=cortex-a7
* -mcpu=cortex-a15
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|
* NEON|NEON_FMA|IDIV_ARM|IDIV_THUMB2
* This flag implies -mfpu=neon-vfpv4.
*
* -mcpu=iwmmxt
* Allows the use of iWMMXt instrinsics with GCC.
*
* IMPORTANT NOTE: These flags should only be tested when
* android_getCpuFamily() returns ANDROID_CPU_FAMILY_ARM, i.e. this is a
* 32-bit process.
*
* When running a 64-bit ARM process on an ARMv8 CPU,
* android_getCpuFeatures() will return a different set of bitflags

/**
* The native activity interface provided by <android/native_activity.h>
* is based on a set of application-provided callbacks that will be called
* by the Activity's main thread when certain events occur.
*
* This means that each one of this callbacks _should_ _not_ block, or they
* risk having the system force-close the application. This programming
* model is direct, lightweight, but constraining.
*
* The 'android_native_app_glue' static library is used to provide a different
* execution model where the application can implement its own main event
* loop in a different thread instead. Here's how it works:
*
* 1/ The application must provide a function named "android_main()" that
* will be called when the activity is created, in a new thread that is
* distinct from the activity's main thread.
*
* 2/ android_main() receives a pointer to a valid "android_app" structure
* that contains references to other important objects, e.g. the
* ANativeActivity object instance the application is running in.
*
* 3/ the "android_app" object holds an ALooper instance that already
* listens to two important things:
*
* - activity lifecycle events (e.g. "pause", "resume"). See APP_CMD_XXX
* declarations below.
*
* - input events coming from the AInputQueue attached to the activity.
*
* Each of these correspond to an ALooper identifier returned by
* ALooper_pollOnce with values of LOOPER_ID_MAIN and LOOPER_ID_INPUT,
* respectively.
*
* Your application can use the same ALooper to listen to additional
* file-descriptors. They can either be callback based, or with return
* identifiers starting with LOOPER_ID_USER.
*
* 4/ Whenever you receive a LOOPER_ID_MAIN or LOOPER_ID_INPUT event,
* the returned data will point to an android_poll_source structure. You
* can call the process() function on it, and fill in android_app->onAppCmd
* and android_app->onInputEvent to be called for your own processing
* of the event.
*
* Alternatively, you can call the low-level functions to read and process
* the data directly... look at the process_cmd() and process_input()
* implementations in the glue to see how to do this.
*
* See the sample named "native-activity" that comes with the NDK with a
* full usage example. Also look at the JavaDoc of NativeActivity.

### Generic Build Instructions
#### Setup
To build GoogleTest and your tests that use it, you need to tell your build
system where to find its headers and source files. The exact way to do it
depends on which build system you use, and is usually straightforward.
### Build with CMake
GoogleTest comes with a CMake build script
([CMakeLists.txt](https://github.com/google/googletest/blob/main/CMakeLists.txt))
that can be used on a wide range of platforms ("C" stands for cross-platform.).
If you don't have CMake installed already, you can download it for free from
<https://cmake.org/>.
CMake works by generating native makefiles or build projects that can be used in
the compiler environment of your choice. You can either build GoogleTest as a
standalone project or it can be incorporated into an existing CMake build for
another project.
#### Standalone CMake Project
When building GoogleTest as a standalone project, the typical workflow starts
with
```
git clone https://github.com/google/googletest.git -b v1.14.0
cd googletest # Main directory of the cloned repository.
mkdir build # Create a directory to hold the build output.
cd build
cmake .. # Generate native build scripts for GoogleTest.
```
The above command also includes GoogleMock by default. And so, if you want to
build only GoogleTest, you should replace the last command with
```
cmake .. -DBUILD_GMOCK=OFF
```
If you are on a \*nix system, you should now see a Makefile in the current
directory. Just type `make` to build GoogleTest. And then you can simply install
GoogleTest if you are a system administrator.
```
make
sudo make install # Install in /usr/local/ by default
```
If you use Windows and have Visual Studio installed, a `gtest.sln` file and
several `.vcproj` files will be created. You can then build them using Visual
Studio.
On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
#### Incorporating Into An Existing CMake Project
If you want to use GoogleTest in a project which already uses CMake, the easiest
way is to get installed libraries and headers.
* Import GoogleTest by using `find_package` (or `pkg_check_modules`). For
example, if `find_package(GTest CONFIG REQUIRED)` succeeds, you can use the
libraries as `GTest::gtest`, `GTest::gmock`.
And a more robust and flexible approach is to build GoogleTest as part of that
project directly. This is done by making the GoogleTest source code available to
the main build and adding it using CMake's `add_subdirectory()` command. This
has the significant advantage that the same compiler and linker settings are
used between GoogleTest and the rest of your project, so issues associated with
using incompatible libraries (eg debug/release), etc. are avoided. This is
particularly useful on Windows. Making GoogleTest's source code available to the
main build can be done a few different ways:
* Download the GoogleTest source code manually and place it at a known
location. This is the least flexible approach and can make it more difficult
to use with continuous integration systems, etc.
* Embed the GoogleTest source code as a direct copy in the main project's
source tree. This is often the simplest approach, but is also the hardest to
keep up to date. Some organizations may not permit this method.
* Add GoogleTest as a git submodule or equivalent. This may not always be
possible or appropriate. Git submodules, for example, have their own set of
advantages and drawbacks.
* Use CMake to download GoogleTest as part of the build's configure step. This
approach doesn't have the limitations of the other methods.
The last of the above methods is implemented with a small piece of CMake code
that downloads and pulls the GoogleTest code into the main build.
Just add to your `CMakeLists.txt`:
```cmake
include(FetchContent)
FetchContent_Declare(
googletest
# Specify the commit you depend on and update it regularly.
URL https://github.com/google/googletest/archive/5376968f6948923e2411081fd9372e71a59d8e77.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
# Now simply link against gtest or gtest_main as needed. Eg
add_executable(example example.cpp)
target_link_libraries(example gtest_main)
add_test(NAME example_test COMMAND example)
```
Note that this approach requires CMake 3.14 or later due to its use of the
`FetchContent_MakeAvailable()` command.
##### Visual Studio Dynamic vs Static Runtimes
By default, new Visual Studio projects link the C runtimes dynamically but
GoogleTest links them statically. This will generate an error that looks
something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
'MDd_DynamicDebug' in main.obj
GoogleTest already has a CMake option for this: `gtest_force_shared_crt`
Enabling this option will make gtest link the runtimes dynamically too, and
match the project in which it is included.
#### C++ Standard Version
An environment that supports C++14 is required in order to successfully build
GoogleTest. One way to ensure this is to specify the standard in the top-level
project, for example by using the `set(CMAKE_CXX_STANDARD 14)` command along
with `set(CMAKE_CXX_STANDARD_REQUIRED ON)`. If this is not feasible, for example
in a C project using GoogleTest for validation, then it can be specified by
adding it to the options for cmake via the`-DCMAKE_CXX_FLAGS` option.
### Tweaking GoogleTest
GoogleTest can be used in diverse environments. The default configuration may
not work (or may not work well) out of the box in some environments. However,
you can easily tweak GoogleTest by defining control macros on the compiler
command line. Generally, these macros are named like `GTEST_XYZ` and you define
them to either 1 or 0 to enable or disable a certain feature.
We list the most frequently used macros below. For a complete list, see file
[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/main/googletest/include/gtest/internal/gtest-port.h).
### Multi-threaded Tests
GoogleTest is thread-safe where the pthread library is available. After
`#include <gtest/gtest.h>`, you can check the
`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
`#defined` to 1, no if it's undefined.).
If GoogleTest doesn't correctly detect whether pthread is available in your
environment, you can force it with
```
-DGTEST_HAS_PTHREAD=1
```
or
```
-DGTEST_HAS_PTHREAD=0
```
When GoogleTest uses pthread, you may need to add flags to your compiler and/or
linker to select the pthread library, or you'll get link errors. If you use the
CMake script, this is taken care of for you. If you use your own build script,
you'll need to read your compiler and linker's manual to figure out what flags
to add.
### As a Shared Library (DLL)
GoogleTest is compact, so most users can build and link it as a static library
for the simplicity. You can choose to use GoogleTest as a shared library (known
as a DLL on Windows) if you prefer.
To compile *gtest* as a shared library, add
```
-DGTEST_CREATE_SHARED_LIBRARY=1
```
to the compiler flags. You'll also need to tell the linker to produce a shared
library instead - consult your linker's manual for how to do it.
To compile your *tests* that use the gtest shared library, add
```
-DGTEST_LINKED_AS_SHARED_LIBRARY=1
```
to the compiler flags.
Note: while the above steps aren't technically necessary today when using some
compilers (e.g. GCC), they may become necessary in the future, if we decide to
improve the speed of loading the library (see
<https://gcc.gnu.org/wiki/Visibility> for details). Therefore you are
recommended to always add the above flags when using GoogleTest as a shared
library. Otherwise a future release of GoogleTest may break your build script.
### Avoiding Macro Name Clashes
In C++, macros don't obey namespaces. Therefore two libraries that both define a
macro of the same name will clash if you `#include` both definitions. In case a
GoogleTest macro clashes with another library, you can force GoogleTest to
rename its macro to avoid the conflict.
Specifically, if both GoogleTest and some other code define macro FOO, you can
add
```
-DGTEST_DONT_DEFINE_FOO=1
```
to the compiler flags to tell GoogleTest to change the macro's name from `FOO`
to `GTEST_FOO`. Currently `FOO` can be `ASSERT_EQ`, `ASSERT_FALSE`, `ASSERT_GE`,
`ASSERT_GT`, `ASSERT_LE`, `ASSERT_LT`, `ASSERT_NE`, `ASSERT_TRUE`,
`EXPECT_FALSE`, `EXPECT_TRUE`, `FAIL`, `SUCCEED`, `TEST`, or `TEST_F`. For
example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
```
GTEST_TEST(SomeTest, DoesThis) { ... }
```
instead of
```
TEST(SomeTest, DoesThis) { ... }
```
in order to define a test.

// A class for indicating whether an assertion was successful. When
// the assertion wasn't successful, the AssertionResult object
// remembers a non-empty message that describes how it failed.
//
// To create an instance of this class, use one of the factory functions
// (AssertionSuccess() and AssertionFailure()).
//
// This class is useful for two purposes:
// 1. Defining predicate functions to be used with Boolean test assertions
// EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
// 2. Defining predicate-format functions to be
// used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
//
// For example, if you define IsEven predicate:
//
// testing::AssertionResult IsEven(int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess();
// else
// return testing::AssertionFailure() << n << " is odd";
// }
//
// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
// will print the message
//
// Value of: IsEven(Fib(5))
// Actual: false (5 is odd)
// Expected: true
//
// instead of a more opaque
//
// Value of: IsEven(Fib(5))
// Actual: false
// Expected: true
//
// in case IsEven is a simple Boolean predicate.
//
// If you expect your predicate to be reused and want to support informative
// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
// about half as often as positive ones in our tests), supply messages for
// both success and failure cases:
//
// testing::AssertionResult IsEven(int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess() << n << " is even";
// else
// return testing::AssertionFailure() << n << " is odd";
// }
//
// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
//
// Value of: IsEven(Fib(6))
// Actual: true (8 is even)
// Expected: false
//
// NB: Predicates that support negative Boolean assertions have reduced
// performance in positive ones so be careful not to use them in tests
// that have lots (tens of thousands) of positive Boolean assertions.
//
// To use this class with EXPECT_PRED_FORMAT assertions such as:
//
// // Verifies that Foo() returns an even number.
// EXPECT_PRED_FORMAT1(IsEven, Foo());
//
// you need to define:
//
// testing::AssertionResult IsEven(const char* expr, int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess();
// else
// return testing::AssertionFailure()
// << "Expected: " << expr << " is even\n Actual: it's " << n;
// }
//
// If Foo() returns 5, you will see the following message:
//
// Expected: Foo() is even
// Actual: it's 5

// Examples:
//
// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
// for (int i = 0; i < 5; i++) {
// EXPECT_DEATH(server.ProcessRequest(i),
// "Invalid request .* in ProcessRequest()")
// << "Failed to die on request " << i;
// }
//
// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
//
// bool KilledBySIGHUP(int exit_code) {
// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
// }
//
// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
//
// The final parameter to each of these macros is a matcher applied to any data
// the sub-process wrote to stderr. For compatibility with existing tests, a
// bare string is interpreted as a regular expression matcher.
//
// On the regular expressions used in death tests:
//
// On POSIX-compliant systems (*nix), we use the <regex.h> library,
// which uses the POSIX extended regex syntax.
//
// On other platforms (e.g. Windows or Mac), we only support a simple regex
// syntax implemented as part of Google Test. This limited
// implementation should be enough most of the time when writing
// death tests; though it lacks many features you can find in PCRE
// or POSIX extended regex syntax. For example, we don't support
// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
// repetition count ("x{5,7}"), among others.
//
// Below is the syntax that we do support. We chose it to be a
// subset of both PCRE and POSIX extended regex, so it's easy to
// learn wherever you come from. In the following: 'A' denotes a
// literal character, period (.), or a single \\ escape sequence;
// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
// natural numbers.
//
// c matches any literal character c
// \\d matches any decimal digit
// \\D matches any character that's not a decimal digit
// \\f matches \f
// \\n matches \n
// \\r matches \r
// \\s matches any ASCII whitespace, including \n
// \\S matches any character that's not a whitespace
// \\t matches \t
// \\v matches \v
// \\w matches any letter, _, or decimal digit
// \\W matches any character that \\w doesn't match
// \\c matches any literal character c, which must be a punctuation
// . matches any single character except \n
// A? matches 0 or 1 occurrences of A
// A* matches 0 or many occurrences of A
// A+ matches 1 or many occurrences of A
// ^ matches the beginning of a string (not that of each line)
// $ matches the end of a string (not that of each line)
// xy matches x followed by y
//
// If you accidentally use PCRE or POSIX extended regex features
// not implemented by us, you will get a run-time failure. In that
// case, please try to rewrite your regular expression within the
// above syntax.
//
// This implementation is *not* meant to be as highly tuned or robust
// as a compiled regex library, but should perform well enough for a
// death test, which already incurs significant overhead by launching
// a child process.
//
// Known caveats:
//
// A "threadsafe" style death test obtains the path to the test
// program from argv[0] and re-executes it in the sub-process. For
// simplicity, the current implementation doesn't search the PATH
// when launching the sub-process. This means that the user must
// invoke the test program via a path that contains at least one
// path separator (e.g. path/to/foo_test and
// /absolute/path/to/bar_test are fine, but foo_test is not). This
// is rarely a problem as people usually don't put the test binary
// directory in PATH.

// This macro is used for implementing macros such as

// death tests are not supported. Those macros must compile on such systems
// if and only if EXPECT_DEATH and ASSERT_DEATH compile with the same parameters
// on systems that support death tests. This allows one to write such a macro on
// a system that does not support death tests and be sure that it will compile
// on a death-test supporting system. It is exposed publicly so that systems
// that have death-tests with stricter requirements than GTEST_HAS_DEATH_TEST
// can write their own equivalent of EXPECT_DEATH_IF_SUPPORTED and
// ASSERT_DEATH_IF_SUPPORTED.
//
// Parameters:
// statement - A statement that a macro such as EXPECT_DEATH would test
// for program termination. This macro has to make sure this
// statement is compiled but not executed, to ensure that
// EXPECT_DEATH_IF_SUPPORTED compiles with a certain
// parameter if and only if EXPECT_DEATH compiles with it.
// regex - A regex that a macro such as EXPECT_DEATH would use to test
// the output of statement. This parameter has to be
// compiled but not evaluated by this macro, to ensure that
// this macro only accepts expressions that a macro such as
// EXPECT_DEATH would accept.
// terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
// and a return statement for ASSERT_DEATH_IF_SUPPORTED.
// This ensures that ASSERT_DEATH_IF_SUPPORTED will not
// compile inside functions where ASSERT_DEATH doesn't
// compile.
//
// The branch that has an always false condition is used to ensure that
// statement and regex are compiled (and thus syntactically correct) but
// never executed. The unreachable code macro protects the terminator
// statement from generating an 'unreachable code' warning in case
// statement unconditionally returns or throws. The Message constructor at
// the end allows the syntax of streaming additional messages into the

// To distinguish different instances of the pattern, (yes, you

//
// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
// in the given test suite, whether their definitions come before or
// AFTER the INSTANTIATE_TEST_SUITE_P statement.
//
// Please also note that generator expressions (including parameters to the
// generators) are evaluated in InitGoogleTest(), after main() has started.
// This allows the user on one hand, to adjust generator parameters in order
// to dynamically determine a set of tests to run and on the other hand,
// give the user a chance to inspect the generated tests with Google Test
// reflection API before RUN_ALL_TESTS() is executed.
//
// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
// for more examples.
//
// In the future, we plan to publish the API for defining new parameter
// generators. But for now this interface remains part of the internal
// implementation and is subject to change.
//
//
// A parameterized test fixture must be derived from testing::Test and from
// testing::WithParamInterface<T>, where T is the type of the parameter
// values. Inheriting from TestWithParam<T> satisfies that requirement because
// TestWithParam<T> inherits from both Test and WithParamInterface. In more
// complicated hierarchies, however, it is occasionally useful to inherit
// separately from Test and WithParamInterface. For example:
class BaseTest : public ::testing::Test {
// You can inherit all the usual members for a non-parameterized test
// fixture here.
};
class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
// The usual test fixture members go here too.
};
TEST_F(BaseTest, HasFoo) {
// This is an ordinary non-parameterized test.
}

// This header implements typed tests and type-parameterized tests.
// Typed (aka type-driven) tests repeat the same test for types in a
// list. You must know which types you want to test with when writing
// typed tests. Here's how you do it:
#if 0
// First, define a fixture class template. It should be parameterized
// by a type. Remember to derive it from testing::Test.
template <typename T>
class FooTest : public testing::Test {
public:
...
typedef std::list<T> List;
static T shared_;
T value_;
};
// Next, associate a list of types with the test suite, which will be
// repeated for each type in the list. The typedef is necessary for
// the macro to parse correctly.
typedef testing::Types<char, int, unsigned int> MyTypes;
TYPED_TEST_SUITE(FooTest, MyTypes);
// If the type list contains only one type, you can write that type
// directly without Types<...>:
// TYPED_TEST_SUITE(FooTest, int);
// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
// tests for this test suite as you want.
TYPED_TEST(FooTest, DoesBlah) {
// Inside a test, refer to the special name TypeParam to get the type
// parameter. Since we are inside a derived class template, C++ requires
// us to visit the members of FooTest via 'this'.
TypeParam n = this->value_;
// To visit static members of the fixture, add the TestFixture::
// prefix.
n += TestFixture::shared_;
// To refer to typedefs in the fixture, add the "typename
// TestFixture::" prefix.
typename TestFixture::List values;
values.push_back(n);
...
}
TYPED_TEST(FooTest, HasPropertyA) { ... }
// TYPED_TEST_SUITE takes an optional third argument which allows to specify a
// class that generates custom test name suffixes based on the type. This should
// be a class which has a static template function GetName(int index) returning
// a string for each type. The provided integer index equals the index of the
// type in the provided type list. In many cases the index can be ignored.
//
// For example:
// class MyTypeNames {
// public:
// template <typename T>
// static std::string GetName(int) {
// if (std::is_same<T, char>()) return "char";
// if (std::is_same<T, int>()) return "int";
// if (std::is_same<T, unsigned int>()) return "unsignedInt";
// }
// };
// TYPED_TEST_SUITE(FooTest, MyTypes, MyTypeNames);
#endif // 0
// Type-parameterized tests are abstract test patterns parameterized
// by a type. Compared with typed tests, type-parameterized tests
// allow you to define the test pattern without knowing what the type
// parameters are. The defined pattern can be instantiated with
// different types any number of times, in any number of translation
// units.
//
// If you are designing an interface or concept, you can define a
// suite of type-parameterized tests to verify properties that any
// valid implementation of the interface/concept should have. Then,
// each implementation can easily instantiate the test suite to verify
// that it conforms to the requirements, without having to write
// similar tests repeatedly. Here's an example:
#if 0
// First, define a fixture class template. It should be parameterized
// by a type. Remember to derive it from testing::Test.
template <typename T>
class FooTest : public testing::Test {
...
};
// Next, declare that you will define a type-parameterized test suite
// (the _P suffix is for "parameterized" or "pattern", whichever you
// prefer):
TYPED_TEST_SUITE_P(FooTest);
// Then, use TYPED_TEST_P() to define as many type-parameterized tests
// for this type-parameterized test suite as you want.
TYPED_TEST_P(FooTest, DoesBlah) {
// Inside a test, refer to TypeParam to get the type parameter.
TypeParam n = 0;
...
}
TYPED_TEST_P(FooTest, HasPropertyA) { ... }
// Now the tricky part: you need to register all test patterns before
// you can instantiate them. The first argument of the macro is the
// test suite name; the rest are the names of the tests in this test
// case.
REGISTER_TYPED_TEST_SUITE_P(FooTest,
DoesBlah, HasPropertyA);
// Finally, you are free to instantiate the pattern with the types you
// want. If you put the above code in a header file, you can #include
// it in multiple C++ source files and instantiate it multiple times.
//
// To distinguish different instances of the pattern, the first
// argument to the INSTANTIATE_* macro is a prefix that will be added
// to the actual test suite name. Remember to pick unique prefixes for
// different instances.
typedef testing::Types<char, int, unsigned int> MyTypes;
INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, MyTypes);
// If the type list contains only one type, you can write that type
// directly without Types<...>:

//
// Similar to the optional argument of TYPED_TEST_SUITE above,

# Customization Points
The custom directory is an injection point for custom user configurations.
## Header `gtest.h`
### The following macros can be defined:
* `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
`OsStackTraceGetterInterface`.
* `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
`testing::TempDir` for semantics and signature.
## Header `gtest-port.h`
The following macros can be defined:
### Logging:
* `GTEST_LOG_(severity)`
* `GTEST_CHECK_(condition)`
* Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
### Threading:
* `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
* `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
* `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
* `GTEST_LOCK_EXCLUDED_(locks)`
### Underlying library support features
* `GTEST_HAS_CXXABI_H_`
### Exporting API symbols:
* `GTEST_API_` - Specifier for exported symbols.
## Header `gtest-printers.h`
* See documentation at `gtest/gtest-printers.h` for details on how to define a
custom printer.

// A sample program demonstrating using Google C++ testing framework.
// This sample shows how to write a simple unit test for a function,
// using Google C++ testing framework.
//
// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
// Step 1. Include necessary header files such that the stuff your
// test logic needs is declared.
//
// Don't forget gtest.h, which declares the testing framework.
#include "sample1.h"
#include <limits.h>
#include "gtest/gtest.h"
namespace {
// Step 2. Use the TEST macro to define your tests.
//
// TEST has two parameters: the test case name and the test name.
// After using the macro, you should define your test logic between a
// pair of braces. You can use a bunch of macros to indicate the
// success or failure of a test. EXPECT_TRUE and EXPECT_EQ are
// examples of such macros. For a complete list, see gtest.h.
//
// <TechnicalDetails>
//
// In Google Test, tests are grouped into test cases. This is how we
// keep test code organized. You should put logically related tests
// into the same test case.
//
// The test case name and the test name should both be valid C++
// identifiers. And you should not use underscore (_) in the names.
//
// Google Test guarantees that each test you define is run exactly
// once, but it makes no guarantee on the order the tests are
// executed. Therefore, you should write your tests in such a way
// that their results don't depend on their order.
//
// </TechnicalDetails>
// Tests Factorial().
// Tests factorial of negative numbers.
TEST(FactorialTest, Negative) {
// This test is named "Negative", and belongs to the "FactorialTest"
// test case.
EXPECT_EQ(1, Factorial(-5));
EXPECT_EQ(1, Factorial(-1));
EXPECT_GT(Factorial(-10), 0);
// <TechnicalDetails>
//
// EXPECT_EQ(expected, actual) is the same as
//
// EXPECT_TRUE((expected) == (actual))
//
// except that it will print both the expected value and the actual
// value when the assertion fails. This is very helpful for
// debugging. Therefore in this case EXPECT_EQ is preferred.
//
// On the other hand, EXPECT_TRUE accepts any Boolean expression,
// and is thus more general.
//
// </TechnicalDetails>
}
// Tests factorial of 0.
TEST(FactorialTest, Zero) { EXPECT_EQ(1, Factorial(0)); }
// Tests factorial of positive numbers.
TEST(FactorialTest, Positive) {
EXPECT_EQ(1, Factorial(1));
EXPECT_EQ(2, Factorial(2));
EXPECT_EQ(6, Factorial(3));
EXPECT_EQ(40320, Factorial(8));

// Tests negative input.
TEST(IsPrimeTest, Negative) {
// This test belongs to the IsPrimeTest test case.
EXPECT_FALSE(IsPrime(-1));
EXPECT_FALSE(IsPrime(-2));
EXPECT_FALSE(IsPrime(INT_MIN));
}
// Tests some trivial cases.
TEST(IsPrimeTest, Trivial) {
EXPECT_FALSE(IsPrime(0));
EXPECT_FALSE(IsPrime(1));
EXPECT_TRUE(IsPrime(2));
EXPECT_TRUE(IsPrime(3));
}
// Tests positive input.
TEST(IsPrimeTest, Positive) {
EXPECT_FALSE(IsPrime(4));
EXPECT_TRUE(IsPrime(5));
EXPECT_FALSE(IsPrime(6));
EXPECT_TRUE(IsPrime(23));
}
} // namespace
// Step 3. Call RUN_ALL_TESTS() in main().
//
// We do this by linking in src/gtest_main.cc file, which consists of
// a main() function which calls RUN_ALL_TESTS() for us.
//
// This runs all the tests you've defined, prints the result, and
// returns 0 if successful, or 1 otherwise.
//
// Did you notice that we didn't register the tests? The
// RUN_ALL_TESTS() macro magically knows about all the tests we
// defined. Isn't this convenient?

// A sample program demonstrating using Google C++ testing framework.
// In this example, we use a more advanced feature of Google Test called
// test fixture.
//
// A test fixture is a place to hold objects and functions shared by
// all tests in a test case. Using a test fixture avoids duplicating
// the test code necessary to initialize and cleanup those common
// objects for each test. It is also useful for defining sub-routines
// that your tests need to invoke a lot.
//
// <TechnicalDetails>
//
// The tests share the test fixture in the sense of code sharing, not
// data sharing. Each test is given its own fresh copy of the
// fixture. You cannot expect the data modified by one test to be
// passed on to another test, which is a bad idea.
//
// The reason for this design is that tests should be independent and
// repeatable. In particular, a test should not fail as the result of
// another test's failure. If one test depends on info produced by
// another test, then the two tests should really be one big test.
//
// The macros for indicating the success/failure of a test
// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
// (when Google Test prints the test result, it tells you which test
// each failure belongs to). Technically, these macros invoke a
// member function of the Test class. Therefore, you cannot use them
// in a global function. That's why you should put test sub-routines
// in a test fixture.
