Worked on the chenrui333/homebrew-core repository to improve the stability and reliability of Neovide and Neovim test integration. Addressed a persistent timing issue by modifying the test harness to wait for actual UI attachment using the Neovim API’s nvim_list_uis() function, rather than inferring readiness from channel status. This adjustment prevented premature server shutdowns and reduced false positives in test results. Introduced explicit timeouts to ensure deterministic test outcomes and cleaner failures, enhancing the reliability of continuous integration pipelines. Utilized Ruby and DevOps skills with a focus on testing, resulting in fewer flaky tests and faster, more reliable feedback cycles.
