GUIDED BY THE BEAUTY OF OUR TEST SUITE

Summary from the TLDR Web Dev newsletter

This developer improved his software project with a comprehensive testing suite. This involved setting up GitHub Actions for cross-platform CI testing, introducing snapshot testing to visually verify screen renders, and using a novel static panic prevention technique. He also used cargo-fuzz to compare his Rust interpreter with a hand-written assembly version, which helped reveal and fix several discrepancies and bugs.
