Automated Testing with GitHub Actions

Suppose you have a test suite for your project. Whenever a collaborator makes changes and opens a Pull Request (PR), you want to ensure their code passes all tests before merging.

GitHub Actions allows you to automatically run your tests (e.g., pytest) every time code is pushed or a PR is created.

Reference Examples

• Demo Repository with Test Code
• GitHub Actions Workflow Setup (tests.yml)

How it Works

1. Local Testing
You write and run tests locally using tools like pytest.

pytest -v test

2. Automated Trigger
When code is pushed to GitHub, the workflow is automatically triggered.

3. Action Details

When you open a Pull Request or push new commits, GitHub Actions runs your test workflow and displays easy-to-spot colored status markers:

• 🟢 Green check: All tests passed—code is safe to merge!
• 🟡 Yellow dot: Tests are running or in progress.
• 🔴 Red x: Some tests failed—you should review and fix the errors before merging.
