Yes. But it’s not possible out-of-the-box. See:

@Daniel_Lozynski - can you put some example code here how to run parallel test with this FBSSimulatorControl? And do you have any experience with running appium parallel iOS tests ?

Btw. Regarding your lastnam, are you from Poland? 🙂

@stefan My family is from Poland, yes 😉

To be precise, FBSimulatorControl won’t help you to establish an environment where you can run tests in parallel but it enables you to start multiple simulators. The problem is not to run tests in parallel, it’s about the limitation of instruments.

I will write more when I have time, but the short version:

- As far as I see it, it’s not possible to start the same simulator multiple times
- It is possible to start different simulators at the same time

Now I think it should be possible to run tests on those simulators via Selenium Grid. Regarding FBSimulatorControl, I have not tried it myself - but I think it should work…
