Webdriver/selenium 2.0 javascript bindings for nodejs

This library is a webdriver module for nodejs. It makes it possible to write super easy selenium tests in your favorite BDD or TDD test framework. Even Cucumber tests are supported. Take a look into the example directory for test samples.

How to install it

Either download it from github or use npm:

npm install webdriverjs

To run tests on your local machine, you have to download a selenium standalone server which executes the selenium commands. You find the latest version here. It is also possible to run the tests in the cloud (e.g. on BrowserStack, Sauce Labs or TestingBot). For more informations, see below.

Example of webdriverjs

Run selenium server first:

java -jar path/to/your/selenium-server-standalone-2.35.0.jar

Webdriverjs has just a few methods. Most of the methods you will use regurarly are the methods available from the client. To begin using Webdriverjs you just need to create a client.

example using Mocha and Chai

var webdriverjs = require('webdriverjs'),
    client = {};

describe('my webdriverjs tests', function(){
    this.timeout(99999999);
    before(function(){
            client = webdriverjs.remote(options);
            client.init();
    });

    it('Github test',function(done) {
        client
            .url('https://github.com/')
            .getElementSize('.header-logo-wordmark', function(err, result) {
                expect(err).to.be.null;
                assert.strictEqual(result.height , 30);
                assert.strictEqual(result.width, 94);
            })
            .getTitle(function(err, title) {
                expect(err).to.be.null;
                assert.strictEqual(title,'GitHub · Build software better, together.');
            })
            .getElementCssProperty('class name','subheading', 'color', function(err, result){
                expect(err).to.be.null;
                assert.strictEqual(result, 'rgba(136, 136, 136, 1)');
            })
            .call(done);
    });

    after(function(done) {
        client.end(done);
    });
});

Sauce Labs support

To run your tests via Sauce Labs, add the following attributes to your option object. If you are using Webdriverjs in a public repository, never publish your Sauce Labs key! Export these informations as enviroment variables.

host: 'ondemand.saucelabs.com', // Sauce Labs remote host
user: '<username>',             // your username
key:  '<access-key>',           // your access key
port: 80

BrowserStack support

You can also run your tests with BrowserStack on a remote machine.

host: 'hub.browserstack.com', // Browserstack remote host
user: '<username>',           // your username
key:  '<access-key>',         // your access key
port: 80

TestingBot support

You can also run your tests with TestingBot on a remote machine.

host: 'hub.testingbot.com', // TestingBot remote host
user: '<client_key>',       // your client key
key:  '<client_secret>',    // your client secret
port: 80

webdriverjs.endAll

If you wish to end all sessions, you can call the endAll method:

require("webdriverjs").endAll(callback);

Where callback is an optional parameter. This method can be used if you run lots of tests, and you want to make sure that all sessions on your selenium server are closed when you are done. Usually its enough to close each client with its end() method, but if you, for some reason, want to make sure that no sessions are open, use endAll(). (note: this method is also available from the client returned from .remote() as well, but its the same as webdriverjs.endAll())

webdriverjs.sessions

To get a list of all open sessions, you can call:

require("webdriverjs").sessions(callback);

which wil return an array with all sessions from selenium (note: this method is also available from the client returned from .remote() as well, but its the same as webdriverjs.sessions()).

Extending

If you which to extend with your own set of commands there is a method called addCommand available from the client object:

var client = require("webdriverjs").remote();

// create a command the returns the current url and title as one result
// just to show an example
client.addCommand("getUrlAndTitle", function(callback) {
    this.url(function(err,urlResult) {
        this.getTitle(function(err,titleResult) {
            var specialResult = {url: urlResult.value, title: titleResult};
            if (typeof callback == "function") {
                callback(err,specialResult);
            }
        })
    });
});

client
    .init()
    .url('http://www.github.com')
    .getUrlAndTitle(function(err,result){
        expect(err).to.be.null;
        assert.strictEqual(result.url,'https://github.com/');
        assert.strictEqual(result.title,'GitHub · Build software better, together.');
    })
    .end();
