TestOps approach is my passion. I not only write automated tests but also design entire strategies. I want to share some basic tips with you.
- Parallel Test Execution with Distributed Agents: Run your test suite across multiple agents or machines in parallel. This reduces test execution time significantly, allowing faster feedback on code changes. Tools like Selenium Grid or cloud-based services enable efficient distribution and parallel execution of tests. You can run tests on different browsers/OS or just to run the tests in parallel (but please remember that your tests should be independent of each other).
- Smart Test Prioritisation with Risk-Based Testing: Use risk-based testing to prioritise tests based on the impact of a feature or code change. Critical functionality is tested thoroughly, while less critical parts are covered by fewer tests or even by none (it should be usually consulted with the product people). This ensures that the most important parts of your application are well-tested while optimising test coverage.
- Containerised Test Environments with Docker: Create isolated and reproducible test environments using Docker containers (you can do it using CI/CD tools like GitLab). This eliminates environment-related issues and ensures consistent test execution across various stages of the development pipeline. Containers also help in quickly setting up and tearing down environments.
- Automated Visual Testing for UI Changes: Integrate automated visual testing tools to capture and compare screenshots of your application’s UI. This helps detect unexpected visual changes caused by code changes and ensures a consistent user experience across different releases. Doing the visual regression by using a “traditional” way (e.g. e2e Selenium tests) is hard. There are good tools/libraries on the market, dedicated to the visual comparison.
- Intelligent Test Reporting and Analytics: Implement comprehensive test reporting with analytics to gain insights into the quality of your application. Track key metrics such as test pass rates, failure patterns, and test execution time. This data-driven approach helps in identifying bottlenecks and areas for improvement in the testing process.
Remember to tailor these tricks&tips to your specific context and tools, and ensure they align with your product, team’s goals and needs.
