A convenient wrapper for adding an environment for the test program. You should call this before RUN_ALL_TESTS() is called, probably in main(). If you use gtest_main, you need to call this before main() starts for it to take effect. For example, you can define a global variable like this: testing::Environment* const foo_env = testing::AddGlobalTestEnvironment(new FooEnvironment); However, we

inline Environment* AddGlobalTestEnvironment(Environment* env) {
  return UnitTest::GetInstance()->AddEnvironment(env);
}
