GitHub Actions Issues

Problem Statement: make lint works locally, but not in the GA workflow

Users are experiencing issues where make lint runs successfully in a local environment but fails during the linting step in the GitHub Actions workflow.

Solution:

To resolve the discrepancies between local linting and GitHub Actions, users should update their workflow configuration to match the workflow.yml file provided in the β€œLab Flask TDD Workflow.” Additionally, they have two options for addressing the linting step.

Detailed Explanation:

Understanding the Problem:

  • Differences between local and CI/CD environments can cause inconsistencies in test results.
  • The GitHub Actions environment must be configured to mirror the local setup as closely as possible.
  • The make lint command must be standardized across environments to ensure that it uses the same parameters and dependencies.

Step-by-Step Solution:

  1. Update GitHub Actions Workflow:
    • Ensure that the .github/workflows/workflow.yml file is consistent with the one provided in the β€œLab Flask TDD Workflow.”
    • The workflow file should define the same environment and steps as used locally.
  2. Option 1 - Update workflow.yml:
    • Locate line 67 in the workflow.yml file and replace it with:

      yamlCopy code
      green -vvv --processes=1 --run-coverage --termcolor --minimum-coverage=95
      
      
    • This ensures that the GitHub Actions workflow uses the same linting command as the local environment.

  3. Option 2 - Update requirements.txt:
    • Include pytest and related packages in the requirements.txt file to match the local testing dependencies:

      
      # Testing dependencies
      pytest==7.4.0
      pytest-pspec==0.0.4
      pytest-cov==4.1.0
      
      
    • By doing so, you ensure that all necessary testing libraries are available in the GitHub Actions environment.

  4. Modify the Makefile:
    • If opting for the second solution, update line 37 in the Makefile to use pytest instead of the existing command:

      pytest --pspec --cov=service --cov-fail-under=95
      
    • This change aligns the local linting command with the one used in GitHub Actions, ensuring consistency.

  5. Re-run GitHub Actions:
    • Commit and push the changes to trigger the GitHub Actions workflow.
    • Monitor the Actions tab in the GitHub repository to ensure that the linting step passes successfully.
