testeq

A stupid simple test library.

• Basic assertions: assert, equal, deepEqual
• Only supports ES6 modules in tests/ folder
• Outputs TAP compliant test results
• Tries to encourage Functional Programming
• Avoids exception based testing
• A splash of colour for the red/green brigade
• No dependencies
• Should work with any of the reporters from (https://github.com/substack/tape) Just be sure to add --no-color
• Follows Standard JS style guide

Caveats

• It cheats a bit by using JSON.stringify to easily do deep comparisons
• Output is sent to STDOUT once all tests have run but I intend to scale this as needed
• I'm still learning FP and realise that some parts are far from it right now

Motivation

• Limited API to force better testing practices
• Only support ES6 modules to keep it minimal
• It's designed not to run with module bundlers I find it (now) an unnecessary step in the test phase

TODO

• Handle async
• Other stuff as needed
• Stream output rather than waiting until the end (Observable?)
• May support TAP version 13 at some point

Usage

Run all .mjs module files under tests/ folder:

bin/testeq [--no-color]

Specify --no-color if you get garbled output or want to plug it into a TAP parser.

all_sorts_test.mjs

import { assert, equal } from '../index.mjs'

export default () => {
  return {
    'the truth is out there': () => {
      return assert(true)
    },

    'all things being equal': () => {
      return equal('matches', 'matches')
    }
  }
}

outputs

1..2
ok 1 the truth is out there
ok 2 all things being equal
