ought

This module combines your underlying Node.js runtime's assert module's assertions with the pleasant diffing output from the ava test runner (which is actually powered by concordance).

To avoid adding unnecessary overhead to your tests, ought goes out of its way to not require any of its diffing and printing dependencies unless one of your assertions has actually failed.

Usage

Install it:

npm install -D ought

Use it:

const ought = require('ought')

module.exports = function myTest () {
  const result = 34 + 43

  ought.equal(result, 77)
}

The other method is ought.notEqual.

API

Assertions

• ought.equal(actual, expected, message) - Other than the pretty failure message, behavior should exactly match assert.deepStrictEqual
• ought.notEqual(actual, expected, message) - This one just calls assert.notDeepStrictEqual

We would've kept the original assertion names, but we hate typing.

Configuration

You can configure ought with ought.config. Defaults follow:

ought.config({
  color: true
})

Output

What does the output look like? The theme's colors need some tweaking, but for now the output of test.js's failing test looks like this:
