在 Azure DevOps 管道中运行 PyTest 任务无限期挂起

Question

I am adding a pipeline step to run unit tests - the test suite is small and should execute quickly. However, the Run PyTest task is timing out. I set the timeout to 15 minutes which should be far more than enough time for the test suite to run (it takes 2.5 seconds for them to run in the IDE)

The logs show the last command being run is:

python.exe -m pytest --color=no -q --test-run-title="Unit Tests" --basetemp="D:\a\1\s" --junitprefix="py%winver%" --cov=test_module_A --cov=test_module_B --cov-report=xml --cov-report=html --pylint "D:\a\1\s\tests\test_module_A.py" "D:\a\1\s\tests\test_module_B.py"

The YAML for my Run PyTest task:

steps:
- task: stevedower.python.PyTest.PyTest@2
  displayName: 'Run PyTest'
  inputs:
    title: 'Unit Tests'
    testroot: tests
    patterns: 'test_*.py'
    resultfile: tests
    doctests: false
    pylint: true
    codecoverage: 'test_module_A, test_module_B'
  timeoutInMinutes: 15

It seems that the tests are not actually executing despite the pytest command being run. I am not aware of any additional logs that I should be looking at for more detailed test run information.

Answer 1

My tests were (unbeknownst to me) attempting to log in to Azure, so the test run was hanging at the login prompt. Be sure to mock out Azure ML Workspace object, not just the GetWorkspace() calls

Answer 2

In the corresponding pipeline job, enabling:

Allow scripts to access the OAuth token

Solved the issue for me.
