TestPlugInRunnerd.exe +格莫克

我们将 cppunit 单元测试构建为 dll 并将其加载到 TestPlugInRunnerd.exe 中以显示我们的结果。我们编写自己的模拟，但我想开始使用模拟框架，例如 gmock。

我下载了 gmock 并链接到它，没有出现太多问题。我使用 gmock 编写了一个模拟，它编译得很好。但后来我在 gmock 常见问题解答中读到了以下内容：

If you want to use something other than Google Test (e.g. CppUnit or CxxTest) as your testing framework, just change the main() function in the previous section to:

int main(int argc, char** argv) {
  // The following line causes Google Mock to throw an exception on failure,
  // which will be interpreted by your testing framework as a test failure.
  ::testing::GTEST_FLAG(throw_on_failure) = true;
  ::testing::InitGoogleMock(&argc, argv);
  ... whatever your testing framework requires ...
}

This approach has a catch: it makes Google Mock throw an exception from a mock object's destructor sometimes. With some compilers, this sometimes causes the test program to crash. You'll still be able to notice that the test has failed, but it's not a graceful failure.

我显然没有 main.c 文件。我需要做什么才能让 gmock 与我的 dll 一起工作？我应该考虑 gmock 的替代品吗？

谢谢，

We build our cppunit unittests as a dll and load it into TestPlugInRunnerd.exe to show our results. We write our own mocks but I'd like to start using a mocking framework such as gmock.

I downloaded gmock and linked against it without much in the way of problems. I have written a mock using gmock and it compiles fine. But then I read the following in the gmock faq:

If you want to use something other than Google Test (e.g. CppUnit or CxxTest) as your testing framework, just change the main() function in the previous section to:

int main(int argc, char** argv) {
  // The following line causes Google Mock to throw an exception on failure,
  // which will be interpreted by your testing framework as a test failure.
  ::testing::GTEST_FLAG(throw_on_failure) = true;
  ::testing::InitGoogleMock(&argc, argv);
  ... whatever your testing framework requires ...
}

This approach has a catch: it makes Google Mock throw an exception from a mock object's destructor sometimes. With some compilers, this sometimes causes the test program to crash. You'll still be able to notice that the test has failed, but it's not a graceful failure.

I obviously don't have a main. What do I need to do to get gmock to work with my dll? Should I consider alternatives to gmock?

Thanks,

Barry

首先，你不可能没有主电源。否则你将如何执行你的单元测试？

其次，您可以创建一个类的静态变量，在其中调用这两个函数，如下所示：

struct GmockInitializer
{
  GmockInitializer()
  {
    ::testing::GTEST_FLAG(throw_on_failure) = true;
    ::testing::InitGoogleMock(0,0);  // << not sure about this. might not work
  }
};
GmockInitializer gmockInitializer;

First, it is not possible that you don't have a main. Otherwise how would you execute your unit tests?

Second, you could create a static variable of a class where you call these two functions, like this :

struct GmockInitializer
{
  GmockInitializer()
  {
    ::testing::GTEST_FLAG(throw_on_failure) = true;
    ::testing::InitGoogleMock(0,0);  // << not sure about this. might not work
  }
};
GmockInitializer gmockInitializer;
