edp-browser-launcher2

Detect the browser versions available on your system and launch them in an isolated profile for automated testing purposes.

You can launch browsers headlessly (using Xvfb or with PhantomJS) and set the proxy configuration on the fly.

It's a fork of benderjs/browser-launcher2.

Differences from browser-launcher2

• config directory relies on package name
• change plist.parseFile to plist.parse

Example

Browser launch

var launcher = require( 'edp-browser-launcher2' );

launcher( function( err, launch ) {
	if ( err ) {
		return console.error( err );
	}

	launch( 'http://cksource.com/', 'chrome', function( err, instance ) {
		if ( err ) {
			return console.error( err );
		}

		console.log( 'Instance started with PID:', instance.pid );

		instance.on( 'stop', function( code ) {
			console.log( 'Instance stopped with exit code:', code );
		} );
	} );
} );

Outputs:

$ node example/launch.js
Instance started with PID: 12345
Instance stopped with exit code: 0

Browser detection

var launcher = require( '../' );

launcher.detect( function( available ) {
	console.log( 'Available browsers:' );
	console.dir( available );
} );

Outputs:
