Hey @twnolan /@matskiv I'm cleanup all old opened PR we have on AeroGear. Do you think it still valid?

[matskiv]

@danielpassos I am not sure.

@psturc @mmusil @b1zzu @jhellar Do you think some part of this proposal are still relevant?

[jhellar]

IMHO this proposal is outdated now, it mainly describes appium and its clients, testing infrastructure and selectors. For information about appium, I don't think we need summary for it here. For clients, as we only test js based apps, I think we should keep using js based tests and appium clients. For integration tests we already use js, which is more readable for execute, which is widely used in those tests. For testing infrastructure, we use jenkins + browserstack (+ mac slave for ios building), but we are considering using circleci instead of jenkins in future. For selectors, as we only test js apps, we don't need to care about native selectors. @danielpassos @psturc @b1zzu @mmusil I will close this PR now, feel free to reopen if you think we should keep it.
