/// This test opens Try Dart! in an iframe.  When opened the first time, Try
/// Dart! will display a simple hello-world example, color tokens, compile the
/// example, and run the result.  We've instrumented Try Dart! to use
/// window.parent.postMessage when the running program prints anything. So this
/// test just waits for a "Hello, World!" message.
