Running and reporting

Deep reference for unreal-automation-system SKILL.md - how to execute the authored tests (editor and command line), how to parse the JSON report, and how to wire the run into CI. Consult after the tests are written.

Session Frontend (Editor)

Per the Automation Test Framework documentation, open Window → Test Automation (or equivalent Session Frontend) inside the Editor. Tests appear as a tree keyed on the test path (the dot-separated string from the test macro). Click Run Tests for selected leaves; results show pass / fail

• log output inline.

Command line

Run tests from the command line by launching the editor / commandlet with -ExecCmds:

UnrealEditor-Cmd.exe MyGame.uproject \
    -ExecCmds="Automation RunTests MyGame.Inventory; Quit" \
    -unattended -nopause -testexit="Automation Test Queue Empty" \
    -ReportOutputPath="artifacts/automation" \
    -log

Variants:

• Automation RunTests <Filter> - run tests matching the path prefix.
• Automation RunAll - run every registered test.
• Automation Quit - quit when queue drains.

On Windows the editor binary is UnrealEditor-Cmd.exe; on macOS / Linux the launcher script is UnrealEditor with the same flags.

Gauntlet for build-farm runs

For full build-and-test pipelines (deploy a packaged build to a target devkit, run automation, collect artifacts), the next layer up is Gauntlet (Unreal's automation harness referenced on the Automation Test Framework page). Out of scope for this skill - gauntlet wraps the same Automation RunTests command-line surface internally.

Parsing results

The -ReportOutputPath directory contains a JSON index.json plus per-test JSON / HTML detail. Top-level shape:

{
  "devices": [{
    "deviceName": "WindowsEditor",
    "instance": "WindowsEditor"
  }],
  "reportCreatedOn": "2026-05-21T10:33:00Z",
  "succeeded": 38,
  "failed": 1,
  "succeededWithWarnings": 2,
  "notRun": 0,
  "totalDuration": 142.7,
  "tests": [
    {
      "fullTestPath": "MyGame.Inventory.AddItem should increase count by the stack amount",
      "testDisplayName": "should increase count by the stack amount",
      "state": "Success",
      "entries": [/* per-step log entries */]
    },
    {
      "fullTestPath": "MyGame.Inventory.AddItem should reject items past max stack",
      "state": "Fail",
      "entries": [/* assertion failure detail */]
    }
  ]
}

(Field names paraphrased from observed Unreal output; the precise schema ships with the engine version under Engine/Source/Runtime/AutomationController/. For CI gating, treat any "state": "Fail" as a failed build.)

There is no public common exit code; parse the JSON or scrape the log for LogAutomationController: Display: Test ...: Result: Fail lines.

CI integration

GitHub Actions example (paraphrased from common Unreal CI patterns; Unreal CI itself is documented inside the editor SDK):

jobs:
  unreal-automation:
    runs-on: windows-2022
    steps:
      - uses: actions/checkout@v4
        with:
          lfs: true
      - name: Run automation tests
        shell: pwsh
        run: |
          $UE = "C:\Program Files\Epic Games\UE_5.4\Engine\Binaries\Win64\UnrealEditor-Cmd.exe"
          & $UE "$PWD\MyGame.uproject" `
            -ExecCmds="Automation RunTests MyGame; Quit" `
            -unattended -nopause `
            -testexit="Automation Test Queue Empty" `
            -ReportOutputPath="$PWD\artifacts\automation" `
            -log
      - uses: actions/upload-artifact@v4
        if: always()
        with:
          name: automation-report
          path: artifacts/automation

CI pipelines typically split the test run into:

• PR job - EAutomationTestFlags::SmokeFilter only ("complete within 1 second" per the framework docs), for sub-minute PR feedback.
• Nightly job - ProductFilter | StressFilter plus screenshot comparison.
