Public Member Functions inherited from flutter::testing::ThreadTest
	ThreadTest ()
fml::RefPtr< fml::TaskRunner >	GetCurrentTaskRunner ()
	Get the task runner for the thread that the current unit-test is running on. This creates a message loop as necessary.
fml::RefPtr< fml::TaskRunner >	CreateNewThread (const std::string &name="")
	Creates a new thread, initializes a message loop on it, and, returns its task runner to the unit-test. The message loop is terminated (and its thread joined) when the test ends. This allows tests to create multiple named threads as necessary.
