desired-capabilities

Tools for generating Selenium browser specs from shorthand strings and objects.

Installation

npm install desired-capabilities

Usage

capabilities(str) or capabilities.parse(str)

Parses the a string in the form:

browser(@versions)?(:platforms)?

where:

• versions can either be a single version or an inclusive numeric range in

the form start..end.

• platforms can be one or more comma-separated platform names or

shorthands, such as xp or win7.

Examples

var caps = require('desired-capabilities');
var assert = require('assert');

assert.deepEqual(caps.parse('ie@8:xp'), {
  browserName: 'internet explorer',
  browserVersion: '8',
  platform: 'Windows XP'
});

Consult the Sauce Labs or BrowserStack docs for a list of available browsers and platforms.

capabilities(obj) or capabilities.expand(object)

Returns an array of variations of the provided capabilities object for each of the browserVersion and platform values, using the same logic as the string parser.

Examples

var caps = require('desired-capabilities');
var assert = require('assert');

assert.deepEqual(caps({
  browserName: 'Chrome',
  browserVersion: '8..9'
}), [
  {
    browserName: 'Chrome',
    browserVersion: 8,
    platform: 'any'
  },
  {
    browserName: 'Chrome',
    browserVersion: 9,
    platform: 'any'
  }
]);

capabilities(array)

Expands or parses all of the values in the array to produce one big list of capabilities. The values in the array may be either strings, objects, or nested arrays.

Examples

var caps = require('desired-capabilities');
var assert = require('assert');

assert.deepEqual(
  caps(['phantomjs', 'ie@8..9', 'chrome@40', {
      browserName: 'ff',
      browserVersion: 36
  }]),
  [
    {
      browserName: 'phantomjs',
      browserVersion: 'any',
      platform: 'any'
    },
    {
      browserName: 'internet explorer',
      browserVersion: 8,
      platform: 'any'
    },
    {
      browserName: 'internet explorer',
      browserVersion: 9,
      platform: 'any'
    },
    {
      browserName: 'chrome',
      browserVersion: '40',
      platform: 'any'
    },
    {
      browserName: 'firefox',
      browserVersion: '36'
      platform: 'any'
    },
  ]
);
