Things to know about

Since Detox 18.0.0 there's some issue with Expo support. So till problem is resolved i stick to detox@17.14.3. and apply patch proposed in this post expo/detox-tools#1 (comment)

This project uses patch-package to append some code to detox-expo-helpers, it's done automatically after installing dependencies in step #3 ('How to run it?' section)
