Ember is built for ambitious web apps and ember cli makes really easy to write tests, but I find that with the current setup, when the test suite growth over 500 unit tests, things to get quite slow, with assertions taking around 40ms each.
I know that a good way to speed up acceptance tests is to reduce animations length, and acceptance tests by necessity will take a considerable time anyway, but unit tests should run fast.
Are there any tricks for this? Did anyone investigate the bottlenecks? Could it be the resolver? The module helper? Any particular things to avoid?
