Run tests with different locales on each run

@galfisher Both locale and language can be achieved in JavaScript alone, by adding support for the following launch arguments: -AppleLanguages (<lang>) and -AppleLocale <lang>

Exactly, we should support this on both platforms though.

Is there an ETA on this? I need to be able to change the language of the app between detox tests for my use case.

It would be cool if this could be achieved by calling device.launchApp(language) in beforeEach(). It seems like this would be a pretty straightforward change to enable this on iOS at least (a great starting point).

Since I'm only running my tests on an iOS simulator, I think it's possible to hack this in for the meantime by somehow awaiting xcrun simctl launch booted <appid> -AppleLanguages "(en-GB)" in beforeEach like @LeoNatan alluded to. Please warn me if this is a bad idea or if I'm missing something :)

Just curious - is there already a public detox API for awaiting custom xcrum commands I can use in the meantime? I feel like I saw something like that somewhere while browsing through the GH issues.

I have a fork of Detox where I just passed a language parameter all the way down to AppleSimUtils where the app is magically launched with xcrun (haven't implemented on Android).

I haven't opened a PR because this issue doesn't have the help wanted tag. Do you want me to open a PR?

[rotemmiz]

Yes please!!!

BTW, seems like the Android solution is pretty straight forward as well, something like adb shell setprop persist.sys.language en;setprop persist.sys.country US;stop;start

[luisnaranjo733]

Cool! I went ahead and opened the PR.

This issue can be closed :)
