linux - GoogleTest CMake 无法识别 TEST_F : Like it's not recognizing GTest something

Question

好吧，我承认，这是个特例。当我们构建我们的应用程序时，我们正在使用 make，所以我将我的测试包含在 src 下的测试文件夹中。然后在与我们的发布文件夹相同的级别，我们创建了一个单元测试文件夹，其中包括我们所有的源文件和我们的测试源文件。

但我的 IDE 是 CLion，它使用 CMake。在我的 CMakeLists.txt 文件中，我包含:

enable_testing()
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIRS})

add_executable(TestProject ${SOURCE_FILES})

target_link_libraries(TestProject ${GTEST_BOTH_LIBRARIES})

我正在创建我的第一个测试夹具。这是代码:

#include "OPProperties.h"
#include "gtest/gtest.h"

namespace {
// The fixture for testing class OPPropertiesTestTest.
    class OPPropertiesTestTest : public ::testing::Test {
    protected:
        // You can remove any or all of the following functions if its body
        // is empty.

        OPPropertiesTestTest() {
            // You can do set-up work for each test here.
        }

        virtual ~OPPropertiesTestTest() {
            // You can do clean-up work that doesn't throw exceptions here.
        }

        // If the constructor and destructor are not enough for setting up
        // and cleaning up each test, you can define the following methods:

        virtual void SetUp() {
            // Code here will be called immediately after the constructor (right
            // before each test).
        }

        virtual void TearDown() {
            // Code here will be called immediately after each test (right
            // before the destructor).
        }

        // Objects declared here can be used by all tests in the test case for OPPropertiesTestTest.
    };


    TEST_F(OPPropertiesTestTest, ThisTestWillFail) {
        EXPECT_EQ(0, 2);
    }

}  // namespace


int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

这是一张截图:

请注意我的 TEST_F 函数中的语法检查器错误。当我开始键入 TEST_F 时，代码补全试图找到一个提升测试函数。

谁能告诉我我还需要添加什么到 CMakeLists.txt 文件中，或者我没有做哪些 GTest 函数没有被识别？

Answer 1

正如 πìντα ῥεῖ 指出的那样，我实际上并没有尝试构建代码。当我这样做时，我第一次收到 pthread 的链接器错误，因此我们在 CMakeLists.txt 文件中添加了以下行:

target_link_libraries(OnePrint pthread)

然后我再次尝试构建并收到这些错误:

/home/user/gtest-1.7.0/lib/.libs/libgtest.so: undefined reference to `pthread_key_create'
/home/user/gtest-1.7.0/lib/.libs/libgtest.so: undefined reference to `pthread_getspecific'
/home/user/gtest-1.7.0/lib/.libs/libgtest.so: undefined reference to `pthread_key_delete'
/home/user/gtest-1.7.0/lib/.libs/libgtest.so: undefined reference to `pthread_setspecific'
collect2: error: ld returned 1 exit status

因此，我搜索了这些错误并找到了 this question .
