I was wondering if it's possible to have different apps being built out of a single repo in React Native. The reason I'm trying to do this would probably be a huge edge case, but it's basically for unit testing RN modules that I'm developing.
I know I can unit test individual components using Enzyme, but I have some modules that are part of a whole framework, and I need to do end-to-end unit tests on them. So my thinking is that I should build the app and run unit tests on it with Appium. But what if there are multiple unit tests? I guess we would need to build multiple separate apps? But there's only one index.js file.
I was reading that I could set up some app targets and schemes (iOS) and equivalent stuff in Android. But how would I handle that on the RN side? Where can I specify which .js file is the entry point for each target? And how does RN handle building different targets?
https://www.dev6.com/frameworks/building-multiple-apps-from-one-react-native-project/ Read this article about setting up multiple schemes and using those to set environment variables that could influence control flow in the app. However, this would mean that I would have to run the unit tests in serial, loading the same app up over and over with different env (not the end of the world, I guess).
I was thinking that if I had multiple index.js files, one for each unit test, I could maybe set up some separate app targets/schemes and use those, but I guess I would have to figure out how to build and run them concurrently for concurrent unit testing. I think that the react-native run-ios and run-android commands just build a single app though, so I'm not sure how I'd fit that into my unit testing workflow.
Any thoughts on this strategy or other possible strategies would be very welcome! Thanks :)
