Running tests

We use Karma for running our Qunit tests.

grunt test-debug

grunt test-dist

To test with a specific version of jquery, run:

bower install jquery#[jquery-version]

Raising issues

Raise bugs or feature requests in the AUI project.


Contributions to AUI are via pull request.

  • Create an issue in the AUI project. Creating an issue is a good place to talk the AUI team about whether anyone else is working on the same issue, what the best fix is, and if this is a new feature, whether it belongs in AUI. If you don't create an issue, we'll ask you to create one when you issue the PR and retag your commits with the issue key.
  • If you have write access to the AUI repo (ie if you work at Atlassian), you can create branches in the main AUI repo - name your branch as issue/{issue-key}-{description}, eg issue/AUI-1337-fix-the-contributor-guide. If you don't have write access, please fork AUI and issue a PR.
  • Ensure all commits are tagged with the issue key (AUI-1337 fixes to contributor guide).
  • Write tests. Unit tests are preferred over integration tests.
  • Most PRs will go into master, however you might want them to go into a stable branch. If so, set the target branch as the stable branch and the AUI team will manage merging stable into master after the PR is through.


AUI supports the following browsers:

  • Chrome latest stable
  • Firefox latest stable
  • Safari latest stable (on OS X only)
  • IE 8 / 9 / 10
