dud.js v0.0.2

dud.js

Experimental JavaScript testing library.

With this testing library you can comment your functions with simple test cases. When dud.js is executed it will run your tests from the comments.

A side effect is that the test cases usually gives you a pretty good documentation of the function (instead of writing long comments)

Here's an example of a function with four tests.

/*
5, true     ➞ "*6*"
20, true    ➞ "*21*"
10, false   ➞ "11"
15, false   ➞ "16"
*/

function warmup2(a, b) {
    if (b)
        return `*${a + 1}*`
    else
        return `${a + 1}`
}

Usage

Install the package:

npm install @happybits/dud

Create a file example.js with this code:

const dud = require('@happybits/dud')

dud.run(

    { path: 'tests/' },

    ['warmup1'],
    ['warmup2', 'oneline'],
    ['warmup3', 'filter', 'oneline'],
    ['warmup4', 'regex'],
)

In the folder tests add the files warmup1.js, warmup2.js, warmup3.js, warmup4.js.

Run example.js
