I have the same problem as @andremalan and I couldn’t find a solution yet. Someone proposed calling Ember.run.cancelTimers (not in the public API but in the code https://github.com/emberjs/ember.js/blob/v1.7.0/packages/ember-metal/lib/run_loop.js#L263) but that doesn’t work well for integration tests. Also, I’m a bit wary of disabling all timers globally. There are some timers I would like to keep active during testing. I’m curious what other people came up with to solve this problem. My solution up until now was to move the tests for the route with infinite timers to the Rails world in Capybara but this is clearly not satisfying.
