Matomo JavaScript Tracker Tests

Setup

JS Tracker tests require an installed Matomo and ensure the [database_tests] section in matomo/config/config.ini.php is set up correctly, i.e. with the correct password to prevent the following error: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: NO)

The tests will create a database named tracker_tests and store several tracking requests in it.

Running tests

Either open http://matomo.example.com/tests/javascript/ in a browser or execute phantomjs testrunner.js on the command line. You can download PhantomJS here.

To execute tests for a specific module use the module URL parameter, for example &module=core.

If you are developing multiple tracker plugin and want to only include tests for a specific tracker plugin (like Travis would do) use the URL parameter plugin as in &plugin=MyPluginName.

Adding tests

You can add additional JS tests by creating a file tests/javascript/index.php within your plugin directory. A test looks for example like this:

<div id="MyPlugin">
    <div id="elementWhichWillBeUsedInMyTest">

    </div>
</div>

<script type="text/javascript">
module('MyPlugin');

test("Matomo MyPlugin", function() {
    expect(2);

    equal( typeof Matomo.MyPlugin, 'object', 'MyPlugin' );

    var MyPlugin = Matomo.MyPlugin;
    equal( typeof MyPlugin.disableTracking, 'object', 'MyPlugin.disableTracking' );
});

test("Matomo MyPlugin enriches tracker", function() {
    expect(2);

    var tracker = Matomo.getAsyncTracker();

    equal( typeof tracker.MyPlugin, 'object', 'MyPlugin' );
    equal( typeof tracker.MyPlugin.trackme, 'function', 'Tracker MyPlugin.trackme');
});

</script>

You don't have to define any div elements or any other HTML except for the script element. However, you may need to add certain HTML elements to test the behaviour of your tracker plugin.
