How do I write tests?

[NorseGaud]

The CONTRIBUTING.md needs a bit of an update. I don't understand how to create the necessary demo app setup to then write tests for. Can someone please update the guide to go from start to finish through what I need to do to write tests?

MAE-199 How do I write tests?

It depends on what kind of functionality you want to test.

For e2e tests, there's https://github.com/mobile-dev-inc/demo_app which is used by the e2e testing GitHub Actions workflow

Thanks @bartekpacia , I'm trying to test #2117 so I'm guessing I'd need to have some sort of wheel picker added to the app. How do I run the demo app in a simulator locally and then make changes to it? I don't see any readme or instructions for this.

flutter pub get
flutter build apk

@NorseGaud the demo_app is a very simple Flutter app, so a bit of know-how of Flutter should be enough for you to run the app and add a wheel picker. Here you can see some prebuilt widgets: https://docs.flutter.dev/ui/widgets

Thanks @bartekpacia , I'm slowly inching that way. I should be able to add a test in the coming days or weeks.
