hey guys. what testing architecture/libraries do you use?

Testing Arch? Mmm, think of TDD or something similar. Libs? Mm some: Spek, Junit, Mockito, Roboelectric, Truth assertions

thanks marlon. I have used Junit before, and they are pretty handy . we can test all business logics in the IDE only, which brings a good confidence in those niche logic functions. I am looking for solutions which could help me in gaining confidence over android components like views / recyclers /adapters etc. just to test weather a text is getting set correctly on the textview. i have to run an instrumentation test. Is it possible to run some tests in the IDE only which can help verify these stuff?

Mm, you can apply that using Espresso, which Is recommended by the android warlords ... Remember that such UI tests are placed in the src/androidTest/ java por kotlin folder

I'd recommend Kaspresso. The awesome wrapper over Espresso (not only) with cool Kotlin DSL.

Nice !!
