-/**
- * Test implementation of AsyncTaskExecutor.
- * <p>
- * This class is thread-safe. As per the contract of the AsyncTaskExecutor, the submit methods must
- * be called from the main ui thread, however the other public methods may be called from any thread
- * (most commonly the test thread).
- * <p>
- * Tasks submitted to this executor will not be run immediately. Rather they will be stored in a
- * list of submitted tasks, where they can be examined. They can also be run on-demand using the run
- * methods, so that different ordering of AsyncTask execution can be simulated.
- * <p>
- * The onPreExecute method of the submitted AsyncTask will be called synchronously during the
- * call to {@link #submit(Object, AsyncTask, Object...)}.
