Google Test Example

# google test
include(FetchContent)
FetchContent_Declare(
        googletest
        URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)


## testing
enable_testing()

add_executable(
        hello_test
        hello_test.cc
)
target_link_libraries(
        hello_test
        GTest::gtest_main
)

include(GoogleTest)
gtest_discover_tests(hello_test)

Quick Start

  1. Add scripts to CmakeLists.txt 
    # google test
include(FetchContent)
FetchContent_Declare(
googletest
URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)


## testing
enable_testing()

add_executable( # TODO: Change this
hello_test  
hello_test.cc
)
target_link_libraries(
hello_test  # TODO: Change this
GTest::gtest_main
)

include(GoogleTest)
gtest_discover_tests(hello_test)  # TODO: Change this
  2. Add test file(e.g. hello_test.cc) 
    #include <gtest/gtest.h>

// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
// Expect two strings not to be equal.
EXPECT_STRNE("hello", "world");
// Expect equality.
EXPECT_EQ(7 * 6, 42);
}
  3. Build and test 
    cmake -S . -B build
cmake --build build
cd build && ctest
