Description

For Ext.js, ember, and perhaps other applications, the test runner could use a direct API for delaying the test suite from running. Here's my current work-around:

window.__testacular__.loaded = function(){};
someApp.on('init', function() {
  window.__testacular__.start();
});

And then add it to the files array in the test config. Haven't had a chance to think about the API for that yet.

Research direction
The issue requests a hook to delay the start of the test suite. The current workaround involves setting window. testacular .loaded and calling start() after an event. A proposed API could be a configuration option or a callback. Investigate the Karma source code to understand the startup sequence, particularly the 'loaded' and 'start' events. Consider adding an option like 'autoStart' or 'startDelay' and document the new feature.
