Mocha to Node.js Test Runner

This migrates Mocha 8.x tests to Node.js (22.x, 24.x) test runner

Features

  • Automatically adds node:test imports/requires
  • Converts global describe, it, and hooks to imported versions
  • Transforms done callbacks to (t, done) signature
  • Converts this.skip() to t.skip()
  • Converts this.timeout(N) to { timeout: N } options
  • Preserves function styles (doesn't convert between function() and arrow functions)
  • Supports both CommonJS and ESM

Examples

Example 1: Basic

Example 2: Async

Example 3: Hooks

Example 4: Done

Example 5: Skipped

Caveats

  • node:test doesn't support the retry option that Mocha has, so any tests using that will need to be handled separately.
