tollo

javascript testing library AAA schema

This project is under development

Purpose

Write declarative, massive, maintenable unit test

Install

$ npm i tollo --save
$ npm i tap -g

tollo use tap as test engine

Quick start

see example/basic.js

const tollo = require('tollo')
 
// sync pure function
function sum (a, b) {
  return a + b
}
 
tollo.add({
  'function sum': {
    describe: 'sum two numbers and get result',
    mode: tollo.mode.SYNC,
 
    act: sum,
 
    cases: [
      {
        describe: 'basic case',
        input: [1, 2],
        output: 3
      },
      {
        input: [1, 5],
        output: 6
      }
    ]
  }
})
 
// sync mutation function
function pop (array) {
  array.pop()
}
 
tollo.add({
  'function pop': {
    describe: 'pop the last element of the given array',
    mode: tollo.mode.SYNC,
 
    act: pop,
    assert: tollo.assert.mutation,
 
    cases: [
      {
        input: [[1, 2]],
        output: [1]
      },
      {
        input: [[1, 2, 3]],
        output: [1, 2]
      },
      // fail
      {
        input: [[4, 5, 6]],
        output: [4]
      }      
    ]
  }
})
 
// async - Promise
const fs = require('fs-extra')
const tools = require('a-toolbox')
 
tollo.add({
  'fs.chmod': {
    mode: tollo.mode.PROMISE,
 
    arrange: async (input, sandbox) => {
      await tools.fs.unlink('/tmp/chmod', true)
      await tools.fs.touch('/tmp/chmod', 0o666)
    },
    act: fs.chmod,
 
    cases: [
      {
        input: ['/tmp/chmod', 0o444]
      },
      {
        input: ['/var/path/none', 0o444],
        throw: new Error('ENOENT')
      }
    ]
  }
})
 
tollo.run()

then run by tap

tap example/basic.js

See documentation for further informations.

TODO

• documentation doc/README.md
• unit test
• PROMISE mode (doc, example, test)
• CALLBACK mode (engine, doc, example, test)
