What problem does it solve?

Helps engineering teams determine whether a codebase's tests provide real, maintainable confidence by identifying missing coverage, weak assertions, and unreliable test architecture that could allow regressions to slip into production.

Core Features & Use Cases

• Coverage adequacy: Detect missing tests for new code paths, untested error cases, and absent regression tests for bug fixes.
• Test quality & assertions: Evaluate whether tests assert behaviour (not implementation), are specific, meaningful, and would fail under simple mutation.
• Test architecture & reliability: Assess pyramid balance, isolation, mock strategy, flakiness, and whether tests are practical for CI pipelines.
• Use Case: Before merging a feature branch, produce a prioritized report of missing or weak tests, estimate confidence, and recommend concrete tests to add.

Quick Start

Review the test suite for the proposed changes and produce a prioritized list of missing tests, flaky areas, and specific recommendations.
