## Running tests

The VisualEditor plugins for MediaWiki can be tested within your MediaWiki install.

[Configure your wiki](https://www.mediawiki.org/wiki/Manual:JavaScript_unit_testing) to
allow running of tests. In `LocalSettings.php`, set:
```php
// https://www.mediawiki.org/wiki/Manual:JavaScript_unit_testing
$wgEnableJavaScriptTest = true;
```

Then open `http://URL_OF_MEDIAWIKI/index.php/Special:JavaScriptTest/qunit`
(for example, <http://localhost/w/index.php/Special:JavaScriptTest/qunit>).
