Ui flows are using Maestro, that allows to write UI E2E tests for Android.

The flows are located in the ui-utils folder with this structure:

• custom - flows that should not be committed to git
• shared - flows usable by other flows
• validate - flows that assert behavior of the app

• Android Pixel 2 emulator 5.0" screen with 1080x1920 resolution and 420dpi
• API 31
• English as system language

To be able to run the flows, you need to install the CLI tools

Ensure a device or emulator is running and execute:

• maestro test ui-flows/validate/compose_simple_message.yml
• maestro test ui-flows/validate/message_details_show_contact_names.yml

Have a look at the documentation on how to write flows.
