python code-coverage sonarcloud sonarscanner

CodeCoverage not showing in SonarCloud in a Python project

I'm trying to include the codecoverage from my Python project.

First I executed the command py.test --cov=tests/ --cov-report xml:cov/coverage.xml to run the tests and report to cov/coverage.xml

My sonar-project.properties file:

sonar.exclusions=tests/**
sonar.python.coverage.reportPaths=cov/coverage.xml
sonar.python.xunit.reportPath=cov/coverage.xml # added this later, see below for the logs
sonar.verbose=true
sonar.python.version=3.8.2

After executing the sonar-scanner command sonar-scanner -Dsonar.organization=****** -Dsonar.projectKey=****** -Dsonar.sources=. -Dsonar.host.url=https://sonarcloud.io -Dsonar.login=********* the code coverage is not included.

In the logs I see it's looking for sonar.coverage.jacoco.xmlReportPaths. Anybody an idea what I'm doing wrong here?

EDIT:

These lines of logs are maybe useful:

Solution

The contents of the coverage.xml file turned out not to be good I think. By running the command coverage run -m pytest -rap --junitxml coverage.xml and afterwards the command coverage xml -i fixed the issue for me. The coverage.xml file is way bigger than the file before.

My sonar-project.properties file looks like this now:

sonar.exclusions=sonar-scanner-3.3.0.1492-linux/jre/**, tests/**, bot.py
sonar.python.coverage.reportPaths=./coverage.xml
sonar.python.version=3.8.2

And this is the sonar-scanner command I'm running:

sonar-scanner \                                     
  -Dsonar.organization=****** \
  -Dsonar.projectKey=****** \
  -Dsonar.sources=. \
  -Dsonar.host.url=https://sonarcloud.io \
  -Dsonar.login=******
