Spirolo reads the tests your green checkmark doesn’t
An alpha command-line tool that analyzes JavaScript and TypeScript test suites, setup files, and CI configuration without running the tests.
- For
- JavaScript and TypeScript test-suite maintainers
- Worth noticing
- The page labels findings advisory, not confirmed bugs, and says benchmark runs used pinned commits on one Linux machine.
Field notes
The example output names concrete test descriptions and shows categories including weak assertions, missing setup guards, skipped tests, and duplicates. Spirolo says a ratchet can make CI reject only newly introduced findings, avoiding a required cleanup of existing results; the page also presents its rules and scores publicly. The performance figures are described as repeated runs on one Linux machine at pinned commits, and the findings are explicitly advisory.
