This is best explained by the video (or see gif below):
You will notice that the Karma progress reporter reports that the tests take milliseconds, but this obviously takes a lot of time ...
I tweeted about it and was told to
Try opening the debug page and open devtools to generate timings that should show you where the slowdown occurs.
So here is a video of this . I'm not sure what they mean by "generate timings ..."
Sometimes my karma tests run very fast, as I expected (and, as reported). Sometimes it works very slowly, but it says that it works in milliseconds. This can happen even if I use describe.onlyfor a small number of tests (but again, not all the time). I think this happens more often the longer the tests work for me (observer).
I use angular , webpack , es6 (with babel ), karma , mocha , chai and sinon .
I notice that even if I create my tests without the karma-webpack plugin and then run the karma on the result, I still see this problem (so I don’t think it is a karma-webpack plugin).
