browser-manifest

An informal specification to describe the basic properties of a browser (in the broadest sense) as well as the features it wants and supports. Includes some code for validating and normalizing a manifest.

Specification

Example

manifest = {
  name: 'chrome',
  version: '26',
  platform: 'windows 2012',
  title: 'Sauce Labs Google Chrome 26 on Windows 2012',
  wants: {
    tunnel: true
  },
  supports: {
    headless: false
  }
}

Properties

name

Required, one of browser-names. Must be a non-empty, lowercase string.

version

Optional but recommended. If defined, it must be a non-empty string. Does not have to be fully qualified, as long as the version is unique among a set of browsers with the same properties. May also be a non-numeric prerelease version like "beta" or "dev". Examples:

  • 6
  • 13.2
  • 11.00.18362.1 (IE)
  • 80.0a1 (Firefox Nightly)
  • beta

title

Optional but recommended. A string for display purposes, for humans to identify this browser among others. Examples:

  • Sauce Labs Google Chrome 27 on Mac 10.12
  • Playwright Firefox
  • System ie 11.00.18362.1

wants

An optional object describing (airtap) features that a browser wants, by the following optional properties:

  • tunnel (boolean): browser needs a tunnel to connect to local test server
  • loopback (boolean): browser needs a hostname other than localhost in order to route 127.0.0.1 traffic through a tunnel.

supports

An optional object describing features supported by a browser, by the following optional properties:

  • headless (boolean): browser can be configured to be headless (TBD: is this distinct from a root headless property that would indicate that the browser is always or never headless?)

options

An optional object with arbitrary properties that exists to customize the browser behavior. Define defaults here, to communicate available options. The options property is ignored in airtap-match-browsers.

provider

Name of the browser-provider that provided this manifest. Not necessary to set, handled internally by Airtap 4.

Additional properties

The manifest may contain additional properties not described here, including nested objects. Such properties can be used by whatever tool launches a browser and by airtap-match-browsers for more specific matching.
