Boosting Test Coverage for Microservices - Laura Vuorenoja
Boosting test coverage for microservices requires a comprehensive approach including code visualization, automated testing, and continuous integration and delivery.
- Automated testing is a crucial aspect of software development, and it’s essential to cover all aspects of the code, not just unit tests.
- Use code visualization tools to identify blind spots in your tests and improve code quality.
- The coverage percentage is meaningful only to project developers and determines how well tests cover the software.
- Automated testing helps prevent regression and ensures that new changes don’t break existing functionality.
- Microservices architecture can make testing more challenging, but tools like Docker and CI/CD pipelines can help.
- Use application tests to test interoperability and validate notifications between services.
- Monitoring code coverage with automated tooling helps improve code quality.
- Don’t rely solely on unit tests, as they may not cover all aspects of the code.
- Write tests first, then write the code to ensure testability.
- Test coverage data can be used to track progress and identify areas for improvement.
- CI/CD pipelines can help automate testing and ensure that tests are run with every change.
- CodeCop.io is a free tool that can be used to track test coverage and provide feedback.
- The coverage percentage is not a good indicator of test quality, and high coverage doesn’t always mean good test quality.
- It’s essential to keep tests simple, modular, and focused on specific code changes.
- Docker and CI/CD pipelines can help automate testing and ensure that tests are run with every change.
