Oh No!

Mutasaurus was unable to generate Mutations for these projects.

Maybe you can help us out! Join the excavation, help dig up better ways to test Deno applications!

Mutations are not run by their respective open source project maintainers. Just like traditional test coverage, the mutation score does not tell the full story of a test suite, and while it may be a better proxy that traditional test coverage for quality, scores should be used as a guide, not a definitive measure. Scores across different projects should not be compared. Projects that did not generate mutations typically indicate an issue with Mutasaurus, not the project under mutation, please report these issues to Mutasaurus maintainers.

Request a run for your project.

I will use your email to update you when your run is complete, then one extra follow up email when I launch the ability to claim accounts.
