This setup runs iOS on a Mac mini instance and Android on a Linux instance, one workflow each, following the rules in Mobile jobs.

Agent prompt

Add Codemagic workflows that run this project's e2e tests on iOS and Android. Docs: https://e2e.tester.army/docs/ci/codemagic.md and https://e2e.tester.army/docs/ci.md

  1. Read both pages.
  2. Add the workflows to codemagic.yaml. Adapt the project paths, scheme, and Node version to this project.
  3. Ask me to add the model key to an e2e environment variable group, marked as secret.
  4. After I start a build, read the build log and fix errors until both workflows pass.

Workflow

The Ubuntu image has AVDs named emulator (API 34), emulator-35, and emulator-36. Linux instances need billing enabled. test_report sends junit.xml to the Tests tab of the build.

Model key

Put the model key in the e2e environment variable group, marked as secret. Each build that reads the group can read the key, untrusted pull request code included. Trigger pull request builds with this group only for contributors you trust. See Model credentials.
