SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reviews what is not tested and prioritizes the highest-risk missing scenarios. This enables teams to focus quality efforts where they matter most.

Core Features & Use Cases

  • Gap detection across unit/integration/end-to-end tests from coverage reports (Codecov, Istanbul, Pytest, etc.)
  • Risk-based prioritization guidance for remediation and test improvements
  • Use during code reviews, audits, or post-incident reviews to surface blind spots

Quick Start

Analyze your test coverage to surface gaps and propose a remediation plan.

FAQPage Schema
How do I identify untested code paths from coverage reports during a code review?

To identify untested code paths, you evaluate coverage reports to surface gaps across unit, integration, and end-to-end tests, then prioritize remediation based on the risk level of those missing scenarios.

What is risk-based testing for prioritizing missing test coverage?

Risk-based testing prioritizes remediation by evaluating the potential impact of untested code paths, enabling teams to focus quality efforts and test improvements where they matter most during audits or code reviews.

Can I use this test coverage analysis with Python Pytest or Codecov reports?

Yes, this test coverage analysis works with reports from Codecov, Istanbul, and Pytest to detect gaps across unit, integration, and end-to-end tests, guiding risk-based testing decisions for your specific stack.

How do I find critical test coverage gaps after a production incident?

You find critical test coverage gaps post-incident by evaluating coverage reports to flag untested code paths, prioritizing remediation based on risk to reveal blind spots and prevent future failures.

What is the best way to prioritize unit and integration test improvements?

The best way to prioritize test improvements is through risk-based testing, which evaluates coverage reports to flag critical gaps and guides remediation efforts toward the highest-risk missing scenarios.

Does this coverage gap detection work for end-to-end tests or only unit tests?

This coverage gap detection works across all test layers, evaluating reports to surface untested paths and prioritize remediation for unit, integration, and end-to-end test coverage simultaneously.
