@wedaly The pause event will be triggered after 1 second (start time is 1, end time is 2). The waitsFor callback executes much more frequently - every 10ms https://github.com/pivotal/jasmine/blob/1_3_x/lib/jasmine-core/jasmine.js#L2560 . I am positive that there will be no problem with this test. Of course, I can increase the end time to 3 or 4 seconds to be sure.
