Hacking company product with reverse engineering ang bytecode instrumentation.

The project I had to write integration test for was really not meant/written for testing. I ended up bytecode instrumenting an internal library to intercept the needed states and results.

I guess everyone in their company knows how to write unit tests except us.

Every. Single. Time. I've tried to learn and implement proper Unit/Instrumentation testing, the main Android devs decide to go for something else or introduce some feature or Gradle plugin that breaks every tutorial out there. I find it way easier to just test everything manually than learning the new yearly trend. Am I the only one?

This is my hell right now.
Android Jetpack compose Instrumentation test with koin di, mockito, coil in a module with 20 other modules.

"Cannot mock/spy coil imagerequest"

Whats yours?
