// additional test results within a single GTest.
//
// Arguments:
//
// - `name` may only contain alphanumeric characters or underscore (_).
// - `name` may not be an empty string.
// - `failure_message` has no character limitations.
// - If no `failure_message` is passed, the SubTestResult is considered
//   successful.
//
// Caveats:
//
// - Must be called on the thread where GTest is running the test case.
// - Only works on desktop, which uses the test launcher.
