16 // A helper class for completion callbacks, designed to make it easy to run
17 // tests involving asynchronous operations. Just call WaitForResult to wait
18 // for the asynchronous operation to complete.
19 //
20 // NOTE: Since this runs a message loop to wait for the completion callback,
21 // there could be other side-effects resulting from WaitForResult. For this
22 // reason, this class is probably not ideal for a general application.
