| // This is a wrapper for gtest's FRIEND_TEST macro that friends |
| // test with all possible prefixes. This is very helpful when changing the test |
| // prefix, because the friend declarations don't need to be updated. |
| // |
| // Example usage: |
| // |
| // class MyClass { |
| // private: |
| // void MyMethod(); |
| // FRIEND_TEST_ALL_PREFIXES(MyClassTest, MyMethod); |
| // }; |
