Karma Benchmark.js Reporter

A configurable Karma reporter for the karma-benchmark plugin.

Installation

npm install karma-benchmark karma-benchmarkjs-reporter --save-dev

Karma Configuration

Add benchmark to your frameworks and reporters arrays. Optionally, specify

module.exports = function(config) {
  config.set({
    // ...
    frameworks: ["benchmark"],
    reporters: ["benchmark"],
    // optional configuration object :
    benchmarkReporter: {
      colors: config.colors,
      style: style,
      decorator: "-",
      terminalWidth: 60,
      hzWidth: 4,
      hzUnits: "ops/sec",
      browserWidth: 40,
      showBrowser: false,
      showSuiteSummary: false,
      formatBenchmark: formatBenchmark,
      formatSuiteHeading: formatSuiteHeading,
      formatSuiteSummary: formatSuiteSummary
    }
  });
};

Options

colors

default: true

This value is inherited from Karma, but you can override it by specifying a boolean.

style

default:

{
  benchmark: chalk.stripColor,
  summaryBenchmark: chalk.underline,
  summaryEmphasis: chalk.bold.underline,
  browser: chalk.blue,
  decorator: chalk.cyan,
  hz: chalk.green,
  hzUnits: chalk.italic.dim,
  suite: chalk.bold.magenta
}

The style object contains the styling functions for piece of data. The default uses chalk for styling and color.

decorator

default: "-"

The decorator for the beginning of each benchmark row.

terminalWidth

default: 60

The default formatting functions attempt to match this column width for each row. There is still possibility for overflow.

hzWidth

default: 4

The default formatting functions use this to pad the formatted hz string.

hzUnits

default: "ops/sec"

The string placed after the hz as units.

browserWidth

default: 40

The default formatting functions use this to pad the browser name.

showBrowser

default: false

The default formatting functions only output the browser name if set to true. It is useful if you are benchmarking multiple browsers.

showSuiteSummary

default: false

Specify if you want to call the formatSuiteSummary function at the end of a suite.

Formatting functions

If you override the default formatting functions, you must ensure that your functions take into account the other configuration values (if you want to use them).
