FAQPage Schema

How do I identify low test coverage modules in JavaScript and Erlang projects?▼

To identify low test coverage, analyze code coverage reports to surface modules with insufficient tests. This process reads coverage outputs and interprets module percentages across JavaScript and Erlang targets to pinpoint testing gaps.

What is the best way to prioritize writing tests for critical paths and public APIs?▼

Prioritize writing tests by ranking uncovered modules according to risk. Analyzing coverage metrics helps guide testing priorities toward public APIs and critical paths where failures have the highest impact.

Can I use coverage analysis to generate remediation recommendations for my codebase?▼

Yes, coverage analysis produces actionable remediation recommendations by evaluating module-level metrics. It interprets coverage data to identify gaps and provides specific guidance on where to focus test-writing efforts.

Does code coverage analysis work for both Erlang and JavaScript targets?▼

Yes, code coverage analysis works across both Erlang and JavaScript targets. It reads coverage outputs from both environments and applies consistent risk ranking to identify testing gaps in either language.

How do I analyze existing coverage reports to find testing gaps quickly?▼

Analyze existing coverage reports by reading the generated outputs and interpreting module-level percentages. This highlights low-coverage areas and ranks targets by risk, allowing you to quickly identify and address testing gaps.
