Example of pytest playwright test automation project

Automation Testing Mission

• Make automated tests useful to the whole software development team, not only a test team.
• Make test results clear and visible to the team.
• make tests small, fast and independent of each other to run in parallel.
• Make tests easy to read, maintain and update.
• Run tests regularly. Preferably on every software change. Introduce different test workflows to achieve different test goals.
• Keep in mind the pyramid of testing. Normally there should not be more E2E tests then integration tests and unit tests.

Test Automation Possible goals

⚠️ If you not sure why do you need test automation, maybe you don't really need it. It is not a magic pill that will solve all your problems.

• Provide quick feedback on software quality on every build and/or deployment
• Automate regression testing to save time and resources and avoide testing routine
• Automate API testing for flawless integration
• Create automated quality gate before UAT testing

Test Automation limitations

Do not start automation testing if...

• You are doing a project with a lot of changes. You will spend more time updating tests than writing new features.
• You are doing a project with a lot of UI changes. UI tests are the most fragile and hard to maintain.
• You are doing a project with a lot of manual testing. Manual testing is still needed and should be done by a human. And it is usually cheaper ¯_(ツ)_/¯
• You don't have experts to do or to validate automation testing.
• You don't have time to do automation testing. It is not a quick task. It is a long term investment.

Installation

1. Install python 3.11 or higher
2. activate virtual environment
3. install poetry pip install poetry
4. run poetry install to install all dependencies
5. install Playwright browsers playwright install
6. to update dependecies if new versions are available or new dependencies are added run poetry update

Run tests

• Check test configuration in pyproject.toml file
  • Make sure tests are running in headless mode
  • Make sure tests are running in parallel
• run pytest to run all tests in the project
• run pytest -m mobile to run mobile tests only
• run pytest -m quality_gate to run QG tests only

Details

• There are examples of GitHub Actions workflows in .github/workflows folder
• There is integration with Testomat.io to sync the test case and to report test results
• Tests a prepared to run in parallel using pytest-xdsit
• Tests are utilizing page object pattern

Plans

• Add a report in CTRF format to generate nice report in the GitHub
