c++ - Qt 中的 GMock 和 undefined reference 错误

Question

我正在尝试在 Windows 中使用 Qt Creator 进行谷歌模拟测试，但结果出现了很多不同的 undefined reference 错误。

我在 Linux 上试过了，它工作正常。我不知道在 Windows 方面我是否对 gmock 进行了错误设置。

这是在 MOCK_CONST_METHOD2、MOCK_METHOD2、MOCK_METHOD1 和前两个 EXPECT_CALL 上存在问题的代码。还有关于 gmock 头文件的问题。

也许您忘记在源代码中添加 gmock 的“.cc”文件。因为在你的.pro文件中，你只添加了gtest的“.cc”文件。

我通常做的是，“添加现有文件”，然后查找 gmock 的 src 文件夹。并添加 .cc 文件。

喜欢这个示例:

SOURCES += \
    ../calculator.cpp \
    ../button.cpp \
    main.cpp \
    gtest/src/gtest.cc \
    gtest/src/gtest-all.cc \
    gtest/src/gtest-death-test.cc \
    gtest/src/gtest-filepath.cc \
    gtest/src/gtest-port.cc \
    gtest/src/gtest-printers.cc \
    gtest/src/gtest-test-part.cc \
    gtest/src/gtest-typed-test.cc \
    gmock/src/gmock-spec-builders.cc \
    gmock/src/gmock-matchers.cc \
    gmock/src/gmock-internal-utils.cc \
    gmock/src/gmock-cardinalities.cc \
    gmock/src/gmock-all.cc \
    gmock/src/gmock.cc
