uloop-run-tests

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]

npx --yes uloop-cli@2.2.0 run-tests --save-before-run true

# Run specific test
npx --yes uloop-cli@2.2.0 run-tests --filter-type exact --filter-value "MyTest.TestMethod"

npx --yes uloop-cli@2.2.0 run-tests --filter-type regex --filter-value ".*Integration.*"

Output

Returns JSON with:

• Success (boolean): Whether all tests passed
• Message (string): Summary message
• CompletedAt (string): ISO timestamp when the run finished
• TestCount (number): Total tests executed
• PassedCount (number): Passed tests
• FailedCount (number): Failed tests
• SkippedCount (number): Skipped tests
• XmlPath (string | null): Path to NUnit XML result file. null when no XML was saved; populated only when tests failed and the XML file exists on disk.

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>
