Really enjoyed listening to @maintainable.fm with @jayroh.dev. My highlights:
- retroactively added tests often skim over real code flaws
- high test coverage != quality
- understanding why a test is difficult to write guides you to a better architecture

Currently working with two Claude Code's on a plugin that sets up and effectively uses undercover for coverage feedback loops.
Claude A is developing the skill. Claude B is a mock project that uses it with --plugin dir. It's been a struggle!
Does this mean we need a skill-writing skill?
Undercover 0.8.4 just dropped with an important bugfix to coverage reported for branched statements spanning multiple lines β¨

"Absolutely essential for ensuring our AI agent-written PRs have the coverage we require."
This is why I build tools, thanks for the shoutout @jaytennier.bsky.social π
Thanks Jay, that means a lot coming from you! More AI workflow stuff is in the works, stay tuned.
Been running ads for Undercover lately with a simple message: your 90% coverage is hiding untested methods, especially in AI-generated code changes.
Undercover catches what coverage percentages miss, right in your PRs and local workflow.
If you saw them, I'd love to hear how the message landed!
Just pushed pronto-undercover 0.4.0 to RubyGems! π ICYMI, it's a great way to integrate undercover with any SCM and any CI workflow and now it supports latest undercover again

Sponsoring @shortruby.com this week again, with updated messaging.
It's now easier than ever to produce thousands lines of code at speeds that make automatic review needed even more.
Undercover guides your coding agent to write complete and higher quality tests.
And lastly, massive performance improvements for analysing large pull requests.
And a Pro plan (279/mo) suitable for large teams with thousands of PRs per month. No changes to open source - Undercover CI remains free to use for public repositories.
LFG! π
Dedicated SimpleCov::Formatter::Undercover.
:nocov: syntax support is fixed, and SimpleCov's add_filter now respects files outside of test coverage reports
Better relative path support allows running undercover in subdirectories and subprojects of monorepos.
Timeline UI with aggregated pull requests stats for your GitHub Org π
Undercover CI repository configuration view
More configs!π οΈ
Ability to skip builds on specific branches via regex.
GitHub status modes: choose between "failure" β to fail builds with coverage warnings (default), or "neutral" π‘ to just get coverage annotations without failing the parent build status.
2025 has brought significant development to both Undercover CI and the undercover gem currently at 0.8.0. Thanks for the feedback and please keep it coming. Here are a few noteworthy changes π§΅
