Instruct QUnit to wait for an asynchronous operation.
DEPRECATED: Add an asynchronous test to run. The test must include a call to QUnit.start().
PARTIALLY DEPRECATED: Start running tests again after the testrunner was stopped. See QUnit.stop() and QUnit.config.autostart.
DEPRECATED: Increase the number of QUnit.start() calls the testrunner should wait for before continuing.
Add a test to run.
