Zerocheck records failure cause, run history, screenshots, recordings, and trend data so engineers can separate likely product regressions from noisy runs.
“At Google, we found that 84% of pass-to-fail transitions are caused by flaky tests - not real bugs.”

“We completely lost trust in our build, and red builds no longer meant anything. Before releases, we would spend about 3 days looking at all the failures and fixing them.”

“To our users, a postmortem without subsequent action is indistinguishable from no postmortem.”
Ben Treynor Sloss, Google VP for 24/7 Operationssource
“Your team had the same incident 3 times. The fix was in the postmortem every time. Nobody did it.”

84% of pass-to-fail transitions at Google are caused by flaky tests, not actual bugs
800 million seconds (25 years) of flaky tests re-run monthly on Buildkite alone
60% of post-incident action items never get completed
Flaky test dashboards show patterns, but engineers still need enough run evidence to decide whether a failure blocks merge. Zerocheck focuses on failure details, run history, screenshots, recordings, and blocking status.
The incident-to-regression gap is worse. The intended flow: incident → root cause → regression test → prevention. In practice, postmortem action items rot in Jira. No tool automates the path from production error to executable regression test.
Developer PRs a typo fix. CI: 5 tests fail. Re-run: 3 pass, 2 still fail. QA investigates for 2 hours. 1 real failure (unrelated), 1 known flake. EM: “Merge it, fix the flake next sprint.” Never fixed. Flake rate hits 40%. Meanwhile: production incident at 2am, postmortem generates “add regression test,” Jira ticket created, deprioritized. 3 months later: same incident recurs.
PR comment and dashboard evidence show the failure cause, screenshots, recording, step trace, and recent run history. Engineers can separate likely product regressions from noisy runs without guessing from a red check alone.
CI failure includes evidence and run history
PR comment shows failure details, blocking status, and evidence
Failure history and trend data make noisy tests visible for repair
Suggested regression tests can be reviewed and approved after incidents
Other tools prove their own platform is secure. Zerocheck produces JSON evidence from your executed application tests.
Get coverage on the flows customers will notice when they break, without turning testing into a quarter-long infrastructure project.
Guard the only code path where a bug is measured in lost dollars per minute.
It records failure cause, run history, screenshots, recordings, and step traces. Engineers can see what happened and whether a pattern looks noisy without relying on a bare red/green check.
Only approved tests configured with blocks_merge can fail the PR status. Non-blocking tests and suggested tests are reported without blocking merge.
Teams can add or approve suggested regression tests after an incident. Those tests only become active PR checks after review and approval.
Know if a failure is real in 30 seconds. Turn every incident into a permanent regression test.
