tddf

WARNING: this is a very early and probably very unstable version.

Overview

Testing framework focused on developer ergonomics.

Highlights

• API 100% compatible (tests run without any modifications) with node-tap, tape and AVA. Migrating to Jest possible via codemod.

• Tests are easily debuggable (just set a breakpoint and run!).

• Does not require a dedicated test runner. Test files are directly runnable (eg. node test.js).

• Includes a test runner anyways, for your convenience.

• Supports async tests (and they run concurrently!).

• Includes a tiny assertion library, but you can use any other you want.

• No dependencies.

• Fast!

Installing

npm install tddf

Then set your test script to tddf in your project's package.json.

Usage

Write your tests

Create a test file anywhere in your project (eg. silly.test.js).

import test from "tddf";
 
test("Stuff", t => {
    t.assert("Things");
});
 
test("Async stuff", async t => {
  const expected = "I come from the future!";
    const result = Promise.resolve(expected);
    t.is(await result, expected);
});

Run your tests

npm test

Other Notes

• Requires Node.js v12.17+ (for ES modules support).
