/**
 Pauses the current test - this is useful for debugging while testing or for test-driving.
 It allows you to inspect the state of your application at any point.
 Example (The test will pause before clicking the button):

 ```javascript
 visit('/')
 return pauseTest();
 click('.btn');
 ```

 You may want to turn off the timeout before pausing.

 qunit (timeout available to use as of 2.4.0):

 ```
 visit('/');
 assert.timeout(0);
 return pauseTest();
 click('.btn');
 ```

 mocha (timeout happens automatically as of ember-mocha v0.14.0):

 ```
 visit('/');
 this.timeout(0);
 return pauseTest();
 click('.btn');
 ```

 @return {Object} A promise that will never resolve
