Automating with GitLab Duo, Part 3: Validating testing

What this post added

This post details a validation test for GitLab Duo's impact on automated testing. The experiment involved removing all existing tests (reducing coverage to 0%) and then using GitLab Duo to regenerate tests. The team measured test coverage and generation time. The results showed an increase in test coverage from 74% to 84% in approximately two days by one engineer, compared to the previous four weeks for multiple engineers. Coverage has since increased to 89%. The post highlights the efficiency gains and the ability for developers with less context to contribute effectively to testing.
