@selul I've fixed all instances where this could happen. Basically for unit tests exit() was replaced by wp_die() so now I'm checking if its a unit test case instance or not.

please try to test more carefully, in order to avoid this back and forth.

@selul I tested it before I pushed in my changes. Please see: https://drive.google.com/file/d/0B_GLg3hHI3Azd0lPZEM5N0p6dlU/view

@contactashish13 and why this is not working ?

Thanks !

@selul ok so the problem was that if pro is on (like it was on my instance), it works properly. Only when pro is deactivated does it not work. Have fixed it. PR: #154

PS - the function visualizer_enable_track() in Module/Admin.php does not have comments so PHPCS is failing at my end. I'm still pushing in the changes.
