How to publish python unittest results to azure pipeline - azure

Question

I am trying to build a pipeline azure DevOps. I build a basic Flask website and wrote a Unittest script for it. It basically all works perfect. When i commit to azure repos the pipeline will do his thing and the test will run. The thing i want is to see the test results, i see all these tutorials for Pytest but not for Unittest.
trigger:
- Development
jobs:
- job: 'Test'
pool:
vmImage: 'ubuntu-latest' # other options: 'macOS-latest', 'windows-latest'
strategy:
matrix:
Python37:
python.version: '3.7'
steps:
- task: UsePythonVersion#0
inputs:
versionSpec: '$(python.version)'
- script: |
python -m pip install --upgrade pip
python -m pip install -e .
displayName: 'Install dependencies'
- script: |
python -m unittest discover -p "*.py" > results.txt
displayName: unittesting
This is my Yaml file that runs the pipeline.
This is how my results look when running the pipeline.
Pipeline results
Is there a way to publish these results with Unittest and have them in azure pipeline.

Answer 1

You'll first need to make your test script generate results in a format that DevOps can understand, i.e. JUnit XML.
There's an example in MS docs (which includes coverage as well):
- script: |
pip install pytest pytest-azurepipelines
pip install pytest-cov
pytest --doctest-modules --junitxml=junit/test-results.xml --cov=. --cov-report=xml
displayName: 'pytest'
Alternatively, using unittest-xml-reporting should give you results in JUnit XML format as well.
Once you have that, then you can use Publish Test Results task to upload results and make them visible in DevOps UI, i.e.:
- task: PublishTestResults#2
inputs:
testResultsFormat: 'JUnit'
testResultsFiles: '**/test-*.xml'

If your unit tests are written using unittest module, dont worry
pytest can run unittest as well !!!
Add below yaml code snippet to your azure pipeline.
Run your unittest with pytest
Generate Junit XML output
Publish the output back to azure pipeline
- script: |
cd $(Build.Repository.LocalPath)
python -m pytest $(Build.Repository.LocalPath)/<unit_tests_path>/*.py --junitxml=test-unit.xml
displayName: 'Run Unit Tests'
- task: PublishTestResults#2
inputs:
testResultsFormat: 'JUnit'
testResultsFiles: 'test-unit.xml'
