fwa

English | Русский | 简体中文

Compiled TypeScript test runner for Node.js®.

fwa runs JavaScript tests emitted by TypeScript, while keeping recursive test discovery deterministic and independent from shell glob behavior.

It does not replace node:test. It prepares a safe file list before delegating execution to the native Node.js test runner.

Installation

npm install --save-dev fwa

fwa does not impose a TypeScript version on the project and does not load the consumer's typescript package.

Quick Start

Recommended script:

{
  "scripts": {
    "build": "tsc",
    "test": "fwa"
  }
}

Run:

npm run build
npm test

fwa does not compile TypeScript. It expects compiled JavaScript tests to already exist in outDir.

When To Use

Use fwa when a project needs a runner that:

• reads rootDir and outDir from TypeScript config;
• recursively finds compiled *.test.js and *.spec.js files;
• blocks compiled tests whose source files no longer exist;
• prunes those files only when --prune is used;
• fails when source tests are newer than compiled tests;
• passes the final file list to native node:test.
