A VS Code extension that automatically plays a sound whenever any test case fails in the integrated terminal — no matter what language or framework you use.
Features
🎵 Plays your custom sound the moment a test failure is detected
🌍 Works with all languages and frameworks: Jest, Pytest, Go test, Cargo/Rust, RSpec, PHPUnit, JUnit, Mocha, Vitest, Cypress, Playwright, dotnet test, ExUnit, and more
⚡ Zero configuration — works out of the box
🔇 Configurable: enable/disable and adjust volume from VS Code settings
🛑 Auto-stops after the sound finishes playing
Requirements
VS Code 1.93.0 or later (Shell Integration must be enabled — it is by default)
How It Works
The extension uses VS Code's Shell Integration API to stream terminal output for every command you run. It scans the output for failure patterns (like FAILED, AssertionError, test(s) failed, ✕, etc.) and plays the sound as soon as a failure is detected.

Sound plays in a hidden WebView panel — if VS Code is in a restricted environment without WebViews, sound won't play
