We run our UI tests in parallel on 3 simulators, and I noticed, that the first one starts executing tests way faster then the rest (because others are still booting, I guess). Also we have our backend server running locally which is used in UI tests. And here comes the problem - I noticed that tests on first simulator are often failing because of the problems with local backend(requests take much more time than usual) exactly in period when other simulators are still booting(tests stop failing when all 3 simulators started running tests). When I tried running tests without parallel simulators problems with backend disappear. So my guess is that simulators booting they take some resources(CPU, memory) which interferes with backend. So my question is there some way to start executing tests only when all parallel simulators are booted?
