Pytest not finding tests on GitHub actions

Question

I'm trying to generate code coverage for a python package I work on and created a GitHub action to do this, which uses the codecov-action. The workflow looks like this:

name: Code Coverage
on: [push]

jobs:
  run:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest]
    steps:
    - uses: actions/checkout@master
    - name: Setup Python
      uses: actions/setup-python@master
      with:
        python-version: 3.7
    - name: Install dependencies
      run: |
        pip install pytest
        pip install pytest-cov
        pip install -r requirements.txt
    - name: Generate coverage report
      run: |
        pytest --cov=./epispot --cov-report=xml
    - name: Upload coverage to Codecov
      uses: codecov/codecov-action@v1
      with:
        verbose: true
        fail_ci_if_error: true

When it's run, it outputs an error, which you can view here. Pytest outputs error code 5 - meaning that no tests were found - but when I run it on my computer, it works properly. Why is this happening?

Answer 1

It may be not the case with you but I had this issue when I was adding a Python test in a branch but added a Github action with pytest to master branch. So, pytest was not finding any tests because there were in fact none.

After I merged master branch with the workflow into that branch with a test, Python build with pytest passed.
