Rovo Dev CLI and Mutation Testing to Write Better Tests

Rovo Dev CLI combines powerful AI with mutation testing tools like Pitest to automatically write high‑quality tests, improve mutation coverage, and raise PRs for you.

Do you want to improve your test suite but find it hard to prioritise the time? Read on to learn how the powerful AI capabilities in Rovo Dev CLI combined with mutation testing can be used to automate writing better tests for you.

In Jira we have been rolling out mutation testing based on Pitest in the backend code bases. This is part of Atlassian’s framework for testing at scale. Our focus has been on improving testing for new code, and code that is being changed, by setting a mutation coverage threshold gate in pull requests. The pull request must pass the threshold to be able to be merged.
