ClickGap autonomous QA files roughly 500 issues and around 200 pull requests in five months
↗
ClickGap is an autonomous QA agent that reviews every merged ClickHouse pull request, designs and executes tests, and files issues and pull requests without human approval.
ClickGap catches defects that survive ClickHouse's existing review and CI, including silent performance regressions and undeclared semantic changes. It attributes each regression to the commit that introduced it, so maintainers can fix issues within hours. This matters because ClickHouse merges 50-100 pull requests daily, and any merged code can ship a bug before a release.
