I want to add my +1 to the goal of unifying and streamlining the setting up of test flows and a common assertion syntax.
I know some of the issues you raise with Promises (like getting a useful stack on exceptions) are being discussed and addressed already. I dont have all the context, but ISTM the task/promise boat has already sailed, so step 1 in the unification effort is ferretting out and fixing issues created or not-solved by this approach before adoption is truly widespread. In the past I've seen real benefit from having some kind of Test or Fixture class/prototype, as well as for a group or suite of tests. It lets you easily share boilerplate for similar tests and gives you a place to hang state and other products of the steps in a test, where they can be tracked and cleaned up during teardown. In the (mochi)tests we'e been writing in browser/metro, we've found need for a few things to facilitate test writing and useful running and reporting behavior, including: * async setUp, i.e. setUp is itself a Task * various helpers for events, observers and other asynchrony tests need to navigate * method spies/stubs * try/catch hackery to allow a suite to complete and report all errors, rather than falling at the first hurdle The guts of the test runner-runner are here: https://mxr.mozilla.org/mozilla-central/source/browser/metro/base/tests/mochitest/head.js#668 .. I'm sure each module and project has some unique requirements but a lot of this stuff feels strongly like it should already exist. Count me in on any efforts to fill this gap. /Sam On Tuesday, May 7, 2013 2:49:49 PM UTC+1, Mike de Boer wrote: > TLDR; in bug 867742 I requested to adopt two JS modules, Async.jsm and > AsyncTest.jsm, in mozilla-central/toolkit/modules.
