FAQPage Schema

How do I check test coverage for specific code symbols before making changes?▼

To check test coverage before changes, this Skill analyzes coverage data from your testing framework to determine which tests cover specific code symbols, preventing regressions before edits are applied.

Why do I need to verify code coverage before modifying a function?▼

Verifying code coverage before modifying a function prevents regressions by ensuring that all code changes are covered by existing tests, stopping edits to uncovered code and maintaining software quality.

Can I use this pre-commit coverage check with any codebase?▼

Yes, this coverage check applies to any codebase, but it requires existing coverage data generated from a supported testing framework to analyze which tests cover the affected code symbols.

What is the best way to prevent regressions when editing uncovered code?▼

The best way to prevent regressions is to check code coverage before changes. If this Skill finds uncovered code, you route it to the appropriate sub-skill for handling to ensure no new bugs are introduced.

How does a pre-commit test coverage analysis work?▼

Pre-commit test coverage analysis works by checking which tests cover each specific code symbol before edits are made, halting changes to uncovered code and ensuring no new bugs are introduced into the codebase.
