| name | uloop-run-tests |
| description | Run Unity Test Runner and report detailed results. Use for EditMode/PlayMode tests, change verification, or failure diagnosis. |
npx --yes uloop-cli@2.2.0 run-tests
Execute Unity Test Runner. This command requires the Unity Test Framework package (com.unity.test-framework). If that package is not installed, the command returns Success: false with an unsupported message and does not affect the other Unity CLI Loop tools.
When tests fail, NUnit XML results with error messages and stack traces are automatically saved. Read the XML file at XmlPath for detailed failure diagnosis.
Before executing tests, npx --yes uloop-cli@2.2.0 run-tests checks for unsaved loaded Scene changes and unsaved current Prefab Stage changes. If any are found, it returns Success: false, keeps TestCount at 0, lists the unsaved items in Message, and does not start the Unity Test Runner. Save or discard those editor changes, then rerun the command. Use --save-before-run true only when the user explicitly asks to save editor changes before continuing.
Usage
npx --yes uloop-cli@2.2.0 run-tests [options]

Success (boolean): Whether all tests passed

CompletedAt (string): ISO timestamp when the run finished
TestCount (number): Total tests executed
PassedCount (number): Passed tests
FailedCount (number): Failed tests

XML Result File
When tests fail, NUnit XML results are automatically saved to {project_root}/.uloop/outputs/TestResults/<timestamp>.xml. The XML contains per-test-case results including:
- Test name and full name
- Pass/fail/skip status and duration
- For failed tests:
<message> (assertion error) and <stack-trace>
