Issue with UnityTestTask@1 - The "path" argument must be of type string. Received type undefined

[IanMoroney]

So, trying to use the example in the docs, and I get the error: The "path" argument must be of type string. Received type undefined when trying to run the task.

This is the debug output from the task:

##[debug]Agent.ProxyUrl=undefined

According to the docs, there isn't an input called path. According to the code, unity-test.ts does refer to path and it joins it with task.json. However, in the above debug output, you can see the check path running which shows a full path to the task.json, so I don't know exactly what's going wrong here.

I assume i'm not missing any required input parameter, and my build environment is fine. If i'm missing something, can you let me know what it is?

YAML:

steps:
- task: UnityTestTask@1
  name: unitytest
  inputs:
    testMode: editMode
    unityProjectPath: $(System.DefaultWorkingDirectory)

@FejZa , have you seen this issue before?

Looks to be the same thing. Looking into it.

Any updates on this?

unityProjectPath is a relative path from the $(Build.SourcesDirectory) and a compile-time string. You can use a string, or compile time expansion syntax e.g. ${{variables.projectPath}}

NB: you should checkout your unity project in the pipeline... but you perhaps need to preserve the Unity Library files etc https://github.com/o-litnon/AzurePipelineUnityTasks/blob/350f90f974d34eaf8b781921a484f203b87019e6/azure-pipelines.yml#L33

Found a workaround in the discord by TheRpgEngineer#6915 You have to use the GetProjectVersion task first, and then pass the version as an argument to the tasks. Example:

- task: UnityGetProjectVersionTask@1
  name: projectversion

- task: UnityTestTask@1
  name: unitytest
  inputs:
    unityProjectPath: $(System.DefaultWorkingDirectory)
    testResultsPath: $(System.DefaultWorkingDirectory)/TestResults
    unityVersion: $(projectversion.projectVersion)
    testMode: editMode
    testCategory: '!PlayMode'

- task: UnityCMDTask@1
  name: unitycmd
  inputs:
    unityVersion: $(projectversion.projectVersion)
    unityProjectPath: $(System.DefaultWorkingDirectory)
    cmdArgs: -executeMethod FirstLight.Editor.EditorTools.BackendMenu.MoveBackendDlls

@FejZa , it doesn't look like unityVersion is a documented input for UnityTestTask, let alone a required field. Should this be added to the docs, and now marked as a required field?

I've also updated the docs here: https://github.com/Dinomite-Studios/unity-azure-pipelines-tasks-docs/pull/17

I’m seeing this same issue. Interestingly it works just fine on one Azure DevOps org and then fails in another with the exact same code 😐
