Patrol Setup

Patrol setup

Get a first Patrol test passing on an Android emulator. Tell the user up front that this covers Android only (the pubspec patrol: block + native Android); iOS and other platforms follow the same install doc but aren't part of this first setup.

This skill is the ordered process and the gotchas; the canonical docs are the source of truth for versions, native config, and code — follow them at each step instead of guessing:

• Install + native setup (dependencies, the patrol: block, Android, iOS, flavors) — https://patrol.leancode.co/documentation
• Write your first test — https://patrol.leancode.co/documentation/write-your-first-test

1. Configure Patrol

Follow the Setup steps, deep-linking to the relevant point:

• Add the patrol dev dependency and the patrol: block in pubspec.yaml — https://patrol.leancode.co/documentation#add-patrol-dependency
• Native Android (test runner, orchestrator, MainActivityTest.java) — https://patrol.leancode.co/documentation#android-setup (Groovy build files: https://patrol.leancode.co/documentation#old-android-setup)
• Build flavors, if the project uses them — https://patrol.leancode.co/documentation#flavors

2. Write a first minimal test

Follow write your first test for the current API: https://patrol.leancode.co/documentation/write-your-first-test

Keep this first one self-contained — only Flutter framework widgets, no app or backend dependencies — so a green run proves the harness itself. Place it in patrol_test/ (or the configured test_directory).

3. Ignore the bundle and secrets

Gitignore test_bundle.dart (generated by Patrol) and .patrol.env (your dart-defines, often secrets) per the Setup section: https://patrol.leancode.co/documentation#setup

4. Run on an emulator

Boot an Android emulator and wait for boot to fully complete before running — a test launched mid-boot fails. Then run the single test with patrol test. A green run confirms the setup.

Gotchas

• MainActivity cannot be resolved (Java) — set the MainActivityTest.java package to the app's applicationId.
• Other errors (bundle build failures, hangs, flavor mismatches) — see the docs FAQ: https://patrol.leancode.co/documentation#faq

Next: Patrol MCP (optional)

Once the setup is green, mention to the user that Patrol MCP exists and can be set up on request — it lets an AI agent run tests, capture screenshots, read the native UI tree, and drive an interactive session. Let the user decide; if they want it, follow the README: https://pub.dev/packages/patrol_mcp
