To have more confidence in our test suite, we need to maintain a stable suite and avoid flaky tests as much as we can. So we should fix them ideally or skip them until they're made stable.

This PR takes a look at the latest commits in master and skips the tests that are flaky.

I'm not sure this is a good fix, mainly a hunch to see if it fixes the instability.

stopDriver being undefined is usually the result of a failure with something else. But I understand that it causes confusion to see this error. I think it should be fine to have this change.

React native android test: see here and here for instance

The first iOS one seems to be related to GitHub servers returning a 500 error during an artifact upload. We did a few fixes (1, 2, 3) recently with iOS tests and they should be quite stable.

The second Android one is indeed flakiness, but stopDriver being undefined is not the real error. It's the one some lines before Appium Settings app is not running after 5000ms.

We're currently working on adding a different kind of e2e test for mobile here, some changes we introduce there should get rid of this Android flakiness. And this time we're making sure it's very robust before merging it by running them consecutively multiple times.

Thanks for looking at this. Flaky tests lead to apathy in regarding failures. It's better to quarantine tests that have hiccups and revisit them
