Webdriver/selenium 2.0 javascript bindings for nodejs Build Status

A WebDriver module for nodejs. Either use the super easy help commands or use the base Webdriver wire protocol commands.

It is written so its easy to add new protocol implementations and add helper commands so make testing easier. Each command resides as one file inside the node module folder which makes it easy to extend.

The two main reasons for this projects are:

  1. Ease of use - Writing tests with webdriver should be very easy

  2. Easy to extend - Adding helper functions, or more complicated sets and combinations of existing commands, should also be very easy.

How to install it

Either download it from github or use npm:

npm install webdriverjs

Example of webdriverjs

Run selenium server first:

java -jar node_modules/webdriverjs/bin/selenium-server-standalone-2.31.0.jar

You can use any nodejs test framework as well as any BDD/TDD assertion library.

example using Mocha and Chai

describe('my webdriverjs tests', function(){

    this.timeout(99999999);
    var client = {};

    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, 68);
            })
            .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);
    });
});

See more examples with other libraries in the example directory.

Extending

If you want to extend with your own set of commands there is a method called addCommand:

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();

Options

desiredCapabilities

Type: Object
Default capabilities:

browserName: 'firefox',  // options: firefox, chrome, opera, safari
version: '',
javascriptEnabled: true,
platform: 'ANY'

If selenium can't find the browser binary, add the path as attribute in your desiredCapabilities object.

for Firefox:

'firefox_binary': <path to binary>
//e.g. '/Applications/Firefox.app/Contents/MacOS/firefox'

for Chrome:

'chrome.binary': <path to binary>

for Opera:

'opera.binary': <path to binary>

for Safari:

'safari.binary': <path to binary>

logLevel

Type: String
Default: verbose
Options: verbose | silent | command | data | result
