?? Boosting Code Coverage with Productive Coverage: A Game-Changer! ??

Code coverage is key for software quality, but traditional methods lack actionability. Productive Coverage steps in to make coverage more focused and effective.

Unlike typical metrics, Productive Coverage prioritizes untested sections similar to well-tested code. This approach helps developers focus on what matters most. ??

1?? Prioritise Similarity in Untested Code:

- Action: Identify untested code that resembles well-tested or frequently executed code.

- Tool: Use AST tools to analyse code patterns across the codebase.

- Impact: This targets high-priority code instead of simply adding more tests.

2?? Set Up a Testedness Scoring Model:

- Action: Create a scoring system combining code coverage and mutation testing data.

- Tip: Calculate scores for each function based on coverage and mutation rates.

- Benefit: Helps focus on impactful tests, not just meeting coverage metrics.

3?? Use Production Data to Prioritise Tests:

- Action: Use CPU or execution metrics to identify critical code paths.

- Steps: Check production logs to see how often code sections run.

- Result: Testing frequently used code catches issues early, boosting reliability.

4?? Make Coverage Suggestions in Code Reviews:

- Action: Provide targeted feedback directly in code reviews with Productive Coverage.

- Best Practice: Only flag high-priority untested lines to avoid overwhelming developers.

- Outcome: This keeps reviews focused, improving test quality and speeding up reviews.

5?? Collect Developer Feedback to Improve:

- Action: Gather developer feedback on coverage suggestions for continuous improvement.

- How: Add quick feedback options (e.g., thumbs-up/down) in reviews.

- Long-Term: Refine scoring models based on feedback for better insights.

Benefits Developers Can Expect:

- Faster Reviews: Reviewers focus on gaps that matter, saving time.

- Better Test Quality: Actionable guidance ensures critical paths are well-tested.

- Fewer Defects: By targeting frequently used code, Productive Coverage helps catch bugs early.
