Google’s gtest not handling friend tests correctly

I was using Google’s gtest unit test framework today and I found an annoying problem – you can’t properly friend test methods that are in a different namespace than the class being tested.

Here is a typical situation:

namespace MyNamespace
{
   class MyClass
   {
      public:
         MyClass(int inData): data(inData){}
      private:
         int data;
   };
}//end namespace

namespace MyNamespace
{
namespace TEST
{
   class MyTestClassFixture
   {
      static const int fixtureData;
   }
   static const MyTestClassFixture::fixtureData = 5;

   TEST_F(MyTestClassFixture, TestEqual)
   {
      MyClass testClass(5);
      ASSERT_EQ(fixtureData, testClass.data);
   }
}
}
