BC aws-device-farm-migration-skill

Migrate test automation from AWS Device Farm to TestMu AI (formerly LambdaTest) in any language or framework. Covers Device Farm desktop browser testing (create_test_grid_url) and mobile runs with test spec YAML, DEVICEFARM_* env vars, device pools, Appium/Espresso/XCUITest/instrumentation uploads. Use this whenever someone wants to move, switch, port, migrate or point tests from AWS Device Farm to TestMu AI or LambdaTest, asks what the TestMu or LT:Options equivalent is for a capability, config, CLI flag or API from AWS Device Farm, mentions create_test_grid_url, CreateTestGridUrl, boto3 devicefarm, DEVICEFARM_DEVICE_NAME, DEVICEFARM_APP_PATH, test spec YAML with phases install/pre_test/test, appium --base-path, 127.0.0.1:4723 inside a Device Farm package, or wants a migration plan, estimate, PR or checklist for a repo currently on AWS Device Farm, even without the word migrate.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

  • 0Tools and files. 1 referenced file(s) missing: ../shared/testmu-cloud-reference.md
  • 0Inputs and preconditions. Does not say what the process needs to start

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
