JavaScript Unit Tests for Core

Recently WordPress added QUnit as a JavaScript unit testing framework and added its first JavaScript unit tests. I thought I would walk through how to run the tests and how to write tests so that we can increase our JavaScript test coverage. All of these are based upon using the develop.svn.wordpress.org checkout which is where the JS unit tests live.

Housekeeping

I’ll be posting a summary soon that covers Wednesday’s marathon meeting to scope out features for 3.5. In the meantime, some housekeeping:

make/core

This P2 blog has moved from wpdevel.wordpress.com to make.wordpress.org/core. The “make” network is still very young, but there are other P2 blogs already underway, including ui, accessibility, themes, and plugins. wppolyglots.wordpress.com also moved to make/polyglots.

Everything was migrated, including email and jabber subscriptions (using Jetpack). Being on the WordPress.org network opens up some possibilities, including custom features, better integration, and single sign-on.

New test framework

There will definitely be more to come on this, but in the last two weeks, the test suite was converted to a new test runner. You can read more about the effort on @maxcutler‘s blog. Tests are now easier and more straightforward to write, and the runner is also faster, leaner, and more stable. We’ve been working to increase our test coverage with every core commit, so this move was really important.

Unit tests and mailing lists

With the new test framework, we’re also looking to raise the visibility of our tests. We do plan to merge them into core’s Subversion repository in the future, but for now, we’ve merged some mailing lists. The wp-svn mailing list (every core commit, right in your inbox) now receives commits to the unit-tests repository as well. And wp-trac (every Trac ticket and comment — “the WordPress firehose”) now receives comments from the unit-tests Trac.

If you are mostly just interested in tests, the wp-unit-tests mailing list receives both commits and Trac notifications, as before. (Also, make yourself known!)

Daily Bug Scrubs

I’d like to continue having daily “office hours.” For now, we’ll continue them weekdays at 19:00 UTC (an hour before the dev chat usually is). A number of us are idling in IRC throughout the week anyway, but I think it has worked well to have a set time where you can stop by to help comb through Trac, bring up tickets for discussion, and pitch patches.
