Microsoft azure devops python pipeline fails with Bash exited with code '5'

Question

I'm following the tutorial at https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/python?view=azure-devops.

Here is my azure-pipelines.yml file:

# Python package
# Create and test a Python package on multiple Python versions.
# Add steps that analyze code, save the dist with the build record, publish to a PyPI-compatible index, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/python

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'
strategy:
  matrix:
    Python27:
      python.version: '2.7'
    Python35:
      python.version: '3.5'
    Python36:
      python.version: '3.6'
    Python37:
      python.version: '3.7'

steps:
- task: UsePythonVersion@0
  inputs:
    versionSpec: '$(python.version)'
  displayName: 'Use Python $(python.version)'

- script: |
    python -m pip install --upgrade pip
    pip install -r requirements.txt
  displayName: 'Install dependencies'

- script: |
    pip install pytest pytest-azurepipelines
    pytest
  displayName: 'pytest'

Running the pipeline fails with the following error message.

Bash exited with code '5'.

I enabled system diagnostics to add debug messages to the log.

The error occurs in the pytest phase of the pipeline.

The full log is available at https://github.com/michaelhochleitner/debug-azure-devops-python-pipeline/blob/master/log.txt.

How can I make the pipeline run without failing?

How can I make the pipeline run without failing?

Agree with phd, the issue comes cause 0 test items can be collected.

Check this detailed answer from cewing:

Pytest gathers tests according to a naming convention. By default any file that is to contain tests must be named starting with test_ and any function in a file that should be treated as a test must also start with test_.

So it's obvious that pytest command can't find any xx.py file whose name starts with test_. So for pytest, there's no available tests for it and this causes the 0 items collected=>Bash exited with code '5'.

I checked your tutorial above and reproduce same issue:

To resolve it and make the run succeed:

For me, I simply created a new test_anyname.py file with content(test_xx.py+test_xx method) below:

And my pipeline then run successfully without Bash exited with code '5':

So you should make sure at least one test item can be found, and the error would go away. Hope it helps :)
