Minimal test runner

Documentation - API · Source

Install

npm install --save-dev testra

Overview

1. Create tests with title and callback (can be async).
2. Call asserts inside test: is, ok, not, throws.
3. Run the tests with run.

import { test, is, ok, run, throws } from 'testra'

test('Test 1', () => {
  ok(true, 'truthy')
  is({ a: 1 }, { b: 2 }, 'deep equal')
  throws(() => someFn(), 'should throw')
})

test('Test 2', async () => {
  await new Promise(resolve => setTimeout(resolve, 1000))
  ok(true, 'async')
})

run()

Universal

The test report uses console to display the results with visual structure.

• In the browser it uses console.group and CSS to style some text.
• On the server it uses ANSI color sequences for the terminal. It also exits with code 1 when any test fails, for use in build and test pipeline.
