// The aura test suite is configured in such a way that Env is shared across
// all tests. If a test needs to install a fresh copy of env it can create an
// instance of this. The constructor destroys the global instance, and the
// destructor reinstates it.
// Typical usage is:
//    MyTest::SetUp() {
//      env_reinstaller_ = std::make_unique<EnvReinstaller>();
//      my_test_env_ = Env::CreateInstance()
//      AuraTestBase::SetUp();
//    }
//    MyTest::TearDown() {
//      AuraTestBase::TearDown();
//      my_test_env_.reset();
//      env_reinstaller_.reset();
//    }
// TODO(sky): this is ugly. Instead look into having each test install it's own
// Env. https://crbug.com/822968
