Boosting Test Coverage for Microservices - Laura Vuorenoja

Testing

Boosting test coverage for microservices requires a comprehensive approach including code visualization, automated testing, and continuous integration and delivery.

Key takeaways

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.
