We improved our testing infrastructure, refactored the backend to use VS Code upstream, and welcomed a handful of new contributors! ## Major Wins We’d love to share the wins with you. Here they are: ### 📈 Added Test Coverage and Increased from 46.86% → 66% In January, we migrated our unit tests from [Mocha to Jest](https://coder.com/%5Bhttps://github.com/cdr/code-server/pull/2564%5D(https://github.com/cdr/code-server/pull/2564)). The switch allows us to move quicker since the team has more experience with Jest. We added [Codecov in April](https://github.com/cdr/code-server/pull/3194) to track coverage. We started at 46.86% coverage and have since then increased it to 66%. It currently leads the way in terms of highest coverage across `coder` repos. ### ↔️ Added End-to-End Testing In February, we [added end-to-end testing](https://github.com/cdr/code-server/pull/2643) with Playwright. This has allowed us to become more confident when releasing.

As of Dec. 14, this has 317 forks. ![](https://www.datocms-assets.com/19109/1642784431-image3.png?fit=clip&fm=webp&w=3840&q=90) ### 🔨 Rewrote VS Code Integration to Lean on Upstream In November, we [rewrote our VS Code integration](https://github.com/cdr/code-server/pull/4414) to lean more heavily on their server. This means fewer patches. We're still working on reducing our patches, but as of right now, there are [only 51 changes](https://github.com/microsoft/vscode/compare/main...cdr:main) that have been changed compared to upstream. ![](https://www.datocms-assets.com/19109/1642784472-image2.png?fit=clip&fm=webp&w=3840&q=90) ### 🌟 +13,173 New GitHub Stars On December 11th, 2020, `coder/code-server` had 37,290 stars.
