App is working fine both in Android and iOS simulators. I am trying to setup Detox with Jest for end to end testing my react-native app. In simulator I can see some movement but app is not launched and I get following errors(apart from "device not defined" I am also getting "app-debug-androidTest.apk: No such file or directory" error, so not sure what is the root cause here).
Console
>detox test --configuration android.emu.debug
node_modules/.bin/jest e2e --config=e2e/config.json --runInBand
server listening on localhost:64281...
