Unity - Test runner

---

GitHub Action to run tests for any Unity project.

Part of the Unity Actions collection.

---

This is a recommended step to prepare your pipeline for using the Build action.

Documentation

See the Unity Actions collection repository for workflow documentation and reference implementation.

Usage

Setup test runner

By default the test runner will run all your playmode and editmode tests.

Create or edit the file called .github/workflows/main.yml and add a job to it.

Personal License

Personal licenses require a one-time manual activation step (per unity version).

Make sure you acquire and activate your license file and add it as a secret.

Then, define the test step as follows:

- uses: webbertakken/unity-test-runner@v1.4
  env:
    UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }}
  with:
    projectPath: path/to/your/project
    unityVersion: 20XX.X.XXXX

Professional license

Professional licenses do not need any manual steps.

Instead, three variables will need to be set.

• UNITY_EMAIL (should contain the email address for your Unity account)
• UNITY_PASSWORD (the password that you use to login to Unity)
• UNITY_SERIAL (the serial provided by Unity)

Define the test step as follows:

- uses: webbertakken/unity-test-runner@v1.4
  env:
    UNITY_EMAIL: ${{ secrets.UNITY_EMAIL }}
    UNITY_PASSWORD: ${{ secrets.UNITY_PASSWORD }}
    UNITY_SERIAL: ${{ secrets.UNITY_SERIAL }}
  with:
    projectPath: path/to/your/project
    unityVersion: 20XX.X.XXXX

That is all you need to test your project.

Storing test results

To be able to access the test results, they need to be uploaded as artifacts. To do this it is recommended to use Github Actions official upload artifact action after any test action.

Using defaults

By default, Test Runner outputs it's results to a folder named artifacts.

Example:

- uses: actions/upload-artifact@v1
  with:
    name: Test results
    path: artifacts

Test results can now be downloaded as Artifacts in the Actions tab.

Specifying artifacts folder

If a different artifactsPath was specified in the test runner, you can reference this path using the id of the test step.

Example:

- uses: webbertakken/unity-test-runner@v1.4
  id: myTestStep
  (...)

- uses: actions/upload-artifact@v1
  with:
    name: Test results
    path: ${{ steps.myTestStep.outputs.artifactsPath }}

Caching

In order to make test runs (and builds) faster, you can cache Library files from previous runs. To do so, simply add Github Actions' official cache action before any unity steps.

Example:

- uses: actions/cache@v1.1.0
  with:
    path: path/to/your/project/Library
    key: Library-MyProjectName-TargetPlatform
    restore-keys: |
      Library-MyProjectName-
      Library-      

This simple addition could speed up your test runs by more than 50%.

Complete example

A complete workflow that tests all modes separately could look like this:

name: Build project

on:
  pull_request: {}
  push: { branches: [master] }

env:
  UNITY_LICENSE: ${{ secrets.UNITY_LICENSE }}

jobs:
  testAllModes:
    name: Test in ${{ matrix.testMode }} on version ${{ matrix.unityVersion }}
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
      matrix:
        projectPath:
          - path/to/your/project
        unityVersion:
          - 2019.2.11f1
        testMode:
          - playmode
          - editmode
    steps:
      - uses: actions/checkout@v2
        with:
          lfs: true
      - uses: actions/cache@v1.1.0
        with:
          path: ${{ matrix.projectPath }}/Library
          key: Library-${{ matrix.projectPath }}
          restore-keys: |
            Library-            
      - uses: webbertakken/unity-test-runner@v1.4
        id: tests
        with:
          projectPath: ${{ matrix.projectPath }}
          unityVersion: ${{ matrix.unityVersion }}
          testMode: ${{ matrix.testMode }}
          artifactsPath: ${{ matrix.testMode }}-artifacts
      - uses: actions/upload-artifact@v1
        with:
          name: Test results for ${{ matrix.testMode }}
          path: ${{ steps.tests.outputs.artifactsPath }}

Note: Environment variables are set for all jobs in the workflow like this.

Configuration options

Below options can be specified under with: for the unity-test-runner action.

projectPath

Specify the path to your Unity project to be tested. The path should be relative to the root of your project.

required: false default: <your project root>

unityVersion

Version of Unity to use for testing the project.

required: false default: 2019.2.1f11

testMode

The type of tests to be run by the test runner.

Options are: "all", "playmode", "editmode"

required: false default: all

artifactsPath

Path where the test results should be stored.

In this folder a folder will be created for every test mode.

required: false default: artifacts

customParameters

Custom parameters to configure the test runner.

Parameters must start with a hyphen (-) and may be followed by a value (without hyphen).

Parameters without a value will be considered booleans (with a value of true).

example:

- uses: webbertakken/unity-test-runner@master
  with:
    customParameters: -profile SomeProfile -someBoolean -someValue exampleValue

required: false default: ""
