What problem does it solve?

This skill guides developers in writing tests for hot-reloading (HMR) and dev-server behavior, ensuring reliability in development workflows.

Core Features & Use Cases

  • Test harness utilities: Provides patterns and utilities (devTest, bake harness, Client) used to drive end-to-end dev-server tests.
  • Coverage of dev-server aspects: Includes tests for bundling, CSS handling, plugins, React refresh, server components, and source maps.
  • Use Case: When creating or modifying a dev server or its hot reload logic, use these tests to validate behavior before release.

Quick Start

Use the dev-server test harness to create a new test under test/bake and run it with your standard test runner to verify hot reload and bundling behaviors.
