Jochen Kemnade commented on TAP5-2239:
--------------------------------------

Can you think of a way to do this in a cross-browser fashion? Maybe we can exchange the {{t5/core/console}} module for the tests?

> I've been wondering why it wasn't possible for selenium-based tests to report back javascript errors as test failures, as they usually indicate some kind of error.
> Taking yet another swing at this a couple of days ago I stumbled upon a firefox plugin (https://github.com/mguillem/JSErrorCollector - Apache v2 licensed) for collecting javascript console errors.
> The plugin is made for webdriver, but it was trivial to get it going with selenium1.
> The attached patch registers a testng listener that after each successful selenium test checks to see if an error was registered in the browser console. In case an error happened; the test success is changed to a failure and some info from the console is set as the throwable.
> To get things going apply the attached patch, and drop the attached xpi into the tapestry-core/src/test/conf/ff_profile_template/extensions folder.
> Then run the core tests. The plugin can be used the other selenium tests by providing the extensions folder in their src/test/conf/ff_profile_template
> This test add-on exposes the ajaxformloop failure reported as TAP5-2228 and TAP5-2230, a place or two where something fails with requirejs related error and one or two other trivialities on my windows machine.
