Benchmark-lib NPM

Benchmark-lib

A function for computing and logging benchmarks React component to render computed benchmarks

npm install benchmark-lib --save

benchmark

import { benchmark } from 'benchmark-lib'

benchmark(foo, bar)
benchmark([foo, bar, baz])

Other arguments (null can be passed to skip argument)

benchmark(
  foo, bar, 'benchName',
  ['test1Name', 'test2Name'], iterations,
  {beforeAll, afterAll, beforeEach, afterEach},
  logEach
)

benchmark([foo, bar, baz], null, 'benchName')

To return results as an object with summary info and an array of objects with computed results

const b = benchmark([foo, bar, baz])

b.fastestTest - string - test name
b.slowestTest - string - test name
b.fastestMS - number
b.slowestMS - number
b.opt - object
- b.opt.benchName
- b.opt.benchStart - Date
- b.opt.benchEnd - Date
- b.opt.benchDuration - ms
- b.opt.iterations - number
- b.opt.callbacks - object - {beforeAll...}
b.res - object - computed results
- b.res.t1 - number - test time in ms
- b.res.t2

Default test names is t1, t2...

Callbacks args

afterAll(result)
beforeEach(testName, testCounter)
afterEach(testName, ms)

Example

for, forEach

let fiboSeq = [1, 1]

const beforeAll = function () {
  for (let i = 2; i < 99; i++) {
    fiboSeq.push(fiboSeq[i-1]+fiboSeq[i-2])
  }
}

const forLoop = function () {
  let clone = fiboSeq.slice()
  for (let i = 0; i < clone.length; i++) {
    clone[i] /= 2
  }
}

const forEachLoop = function () {
  let clone = fiboSeq.slice()
  clone.forEach((o, i) => {
    clone[i] = o / 2
  })
}

benchmark(forLoop, forEachLoop, 'for, forEach benchmark', ['for', 'forEach'])

Benchmark component

import { Bench } from 'benchmark-lib'
import 'benchmark-lib/dist/style.css'

<Bench
  firstTest={foo}
  secondTest={bar}
/>

<Bench
  tests={[foo, bar, baz]}
  benchName='benchmark'
  testNames={['foo', 'bar', 'baz']}
  iterations={500}
  callbacks={{beforeAll, afterAll, beforeEach, afterEach}}
/>
