Mastering Code Coverage

Achieving high code coverage isn't just about throwing tests at your codebase. This use case empowers you to become a code coverage ninja, leveraging data to strategically identify gaps and write effective tests that truly matter. By understanding where coverage is lacking and focusing your efforts on critical areas, you'll boost overall code quality, minimize blind spots, and build software with confidence.

Step-by-Step Tutorial

1. Analyze Your Coverage Landscape

• Utilize SeaLights' Test Gaps Analysis to visualize covered and uncovered sections of your codebase.

• Identify modules, functions, or conditions with low coverage, prioritizing areas based on business logic, risk assessments, and historical bug trends.

2. Dive Deeper with Granularity

• Drill down into uncovered methods to understand their purpose and potential impact.

• Analyze historical defect data to identify areas historically prone to issues, even with existing coverage.

3. Craft Targeted Tests

• Design test cases specifically addressing the identified coverage gaps, ensuring thorough testing of functionality and edge cases.

• Consider different testing techniques (component, integration, etc.) depending on the specific gap and context.

4. Monitor & Iterate

• Rerun test gaps report after writing new tests to track progress and visualize improvement.

• Continuously analyze new code additions and refactorings, identifying new potential coverage gaps as your code evolves.

5. Share & Collaborate

• Communicate coverage insights and progress with fellow developers and testers, fostering team ownership of code quality.

• Encourage knowledge sharing and collaboration on test automation strategies for efficient ongoing coverage maintenance.

Remember, data is your guide, empowering you to write tests that make a real difference for quality and user experience.
