Hello, I am quite curious about writing test cases of start-up and big companies.

In Case , We have an Mobile (Android/iOS) app and Backend ( Ktor ) :

1. Do you usually write UI Tests (End to End ) and Unit Tests (Local) or one of them for each platform? Why ?
2. How many percentage of code coverage and test coverage is enough to delivery ? Why?

In my opinion, I have to write Selenium/Appium instead Native Test ( Espresso for Android / XCTest for iOS /. Postman for API - Ktor ) to reduce cost and time of development.

How’s about your opinion ?
Thanks.

reduce cost and time of development

IMO this is a very believable lie we tell to ourselves. Writing tests with poorer quality in the name of speed almost always ends up in an unmaintainable system. "We'll rush now and write better tests/code later"
