// 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, TestName);
// };
#define FRIEND_TEST_ALL_PREFIXES(test_case_name, test_name) \
FRIEND_TEST(test_case_name, test_name); \
FRIEND_TEST(test_case_name, DISABLED_##test_name); \
FRIEND_TEST(test_case_name, FLAKY_##test_name)
// C++ compilers will refuse to compile the following code:
//
// namespace foo {
// class MyClass {
// private:
// FRIEND_TEST_ALL_PREFIXES(MyClassTest, TestName);
// bool private_var;
// };
// } // namespace foo
//
// class MyClassTest::TestName() {
// foo::MyClass foo_class;
// foo_class.private_var = true;
// }
//
// Unless you forward declare MyClassTest::TestName outside of namespace foo.
// Use FORWARD_DECLARE_TEST to do so for all possible prefixes.
//
// Example usage:
//
// FORWARD_DECLARE_TEST(MyClassTest, TestName);
//
// namespace foo {
// class MyClass {
// private:
// FRIEND_TEST_ALL_PREFIXES(::MyClassTest, TestName); // NOTE use of ::
// bool private_var;
// };
// } // namespace foo
//
// class MyClassTest::TestName() {
// foo::MyClass foo_class;
// foo_class.private_var = true;
// }
