For engineering teams who ship fast
Valid Test Coverage Confidence.
Smart coverage - Terminate software bugs
TestCoverNet builds deterministic, mutation-validated tests that prove effectiveness, not just line coverage. Every published test verifies actual bug detection through mutation scoring, spanning unit, integration and API tests — including tests with real DB/queue dependencies — and arrives as a reviewable pull request: secure isolated execution, no code or snapshots retained after a run.
Zero flake by construction: unlike line-coverage metrics that ship meaningless assertions, mutation coverage captures what actually matters — whether tests catch real bugs. Runs on every pull request, climbs coverage where it counts, and catches regressions before merge.

How it works
Connect your repo
Point TestCoverNet at your codebase with read-only access — GitHub, GitLab, Gitea or Bitbucket. Activate onboarding (optional) and continuous pull request coverage.
AI maps and writes tests
It works methodically through every code path, finds what's untested, and generates focused tests that are pushed to pull request for you review.
Terminate bugs on every Pull-Request
Coverage climbs, while bugs and regressions are caught before merge. Always on, no manual triggering.
