grade v0.1.0

grade

Run benchmark files and gather reports.

Install

Install with npm:

npm i -g grade

Usage

Create a new benchmark file in the benchmark folder and setup some benchmarks:

var grade = require('grade');

// create a new instance of Benchmark
var Benchmark = grade.Benchmark;
var benchmark = new Benchmark();

// create a method that will run before the method under test
var beforeI = 0;
function before () {
  beforeI++;
}

// create a method that will run after the method under test
var afterI = 0;
function after () {
  afterI++;
}

// create the actual method under test
var total = 0;
var test = function () {
  var i = 0;
  while ((i++) < 50000) {}
  total += (beforeI + afterI);
};

// add the actual benchmark to the list of benchmarks to run
benchmark.add('main', test, before, after);

// export the benchmark object so the runner knows what to run
module.exports = benchmark;

Grade

Grade the benchmarks and return the results

• options {Object}: Options containing files
• return {Array} List of results

Benchmark

Create a new instance of Benchmark. Use this to add benchmarks in a file.

• options {Object}: Additional options to pass to timer.execute

Add a new benchmark to the run.

• title {String}: Describe the benchmark.
• fn {Function}: The actual function to run.
• before {Function}: A function to call before the benchmark is run.
• after {Function}: A function to call after the benchmark is run.

Run the registered benchmarks and return timings.

• return {Array} List of timings.

Timer

Execute a benchmark for the specified number of seconds. Seconds is an accumulation of the actual run time of the function under test. This ensures the timing and setup/teardown steps don't interfer with the actual benchmark.

• max {number}: Number of seconds to run the tests for.
• fn {Function}: Function under test
• beforeFn {Function}: Function to run before running the test
• afterFn {Function}: Function to run after running the test
• return {Object} Results of the benchmark
