Testing tools
Flakiness, coverage gaps, test pyramids, and mock strategy - the health of your test suite, measured.
Load Testing Capacity Calculator
Concurrent users and response time to required req/sec.
Test Flakiness Rate Calculator
Total runs and failures to a flakiness score - peaks near a 50/50 split, not a consistent failure.
Test Coverage Gap Calculator
Total lines, covered lines, and a target % to exactly how many more lines need coverage.
Test Selector Robustness Checker
Paste a CSS or test selector - flagged robust, moderate, or fragile based on what breaks in CI.
Test Pyramid Ratio Calculator
Unit, integration, and e2e counts - your test shape, and whether it inverted into the ice cream cone.
Flaky Test CI Cost Calculator
Flake rate, retry count, and CI cost per minute - the real monthly cost flaky tests are burning.
Jest Mock Reset Strategy Explainer
clearMocks vs resetMocks vs restoreMocks - what each does, cumulative not alternative.
