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.

Have a look at the many examples.

For news or announcements follow @webdriverjs on Twitter.

How to install it

npm install webdriverjs

Disclaimer

This is not the official WebdriverJS driver, for differences between this and the official driver, please take a look on this issue post.

Usage

webdriverjs implements most of selenium's JsonWireProtocol.

Make sure you have a running selenium standalone/grid/hub.

Or use selenium-standalone package to run one easily.

var webdriverjs = require('../index');
var options = {
    desiredCapabilities: {
        browserName: 'chrome'
    }
};

webdriverjs
    .remote(options)
    .init()
    .url('http://www.google.com')
    .title(function(err, res) {
        console.log('Title was: ' + res.value);
    })
    .end();

See the full list of options you can pass to .remote(options)

See helpers and protocol methods.

Options

desiredCapabilities

Type: Object

Example:

browserName: 'chrome',  // options: firefox, chrome, opera, safari
version: '27.0',        // browser version
platform: 'XP',         // OS platform
tags: ['tag1','tag2'],  // specify some tags (e.g. if you use Sauce Labs)
name: 'my test'         // set name for test (e.g. if you use Sauce Labs)

See the selenium documentation for a list of the available capabilities.

logLevel

Type: String

Default: silent

Options: verbose | silent | command | data | result

screenshotPath

Saves a screenshot to a given path if selenium driver crashes

Type: String|null

Default: null

singleton

Type: Boolean

Default: false

Set to true if you always want to reuse the same remote

Selector API

The JsonWireProtocol provides several strategies to query an element. WebdriverJS simplifies these to make it more familiar with the common existing selector libraries like Sizzle. The following selector types are supported:

CSS query selector
e.g. client.click('h2.subheading a', function(err,res) {...}) etc.
link text
To get an anchor element with a specific text in it (f.i. <a href="http://webdriver.io">WebdriverJS</a>) query the text starting with an equal (=) sign. In this example use =WebdriverJS
partial link text
To find a anchor element whose visible text partially matches your search value, query it by using *= in front of the query string (e.g. *=driver)
tag name
To query an element with a specific tag name use <tag> or <tag />
name attribute
For quering elements with a specific name attribute you can eather use a normal CSS3 selector or the provided name strategy from the JsonWireProtocol by passing something like [name="some-name"] as selector parameter
xPath
It is also possible to query elements via a specific xPath. The selector has to have a format like for example //BODY/DIV[6]/DIV[1]/SPAN[1]

In near future WebdriverJS will cover more selector features like form selector (e.g. :password,:file etc) or positional selectors like :first or :nth.

Adding custom commands

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(cb) {
    this.url(function(err,urlResult) {
        this.getTitle(function(err,titleResult) {
            var specialResult = {url: urlResult.value, title: titleResult};
            cb(err,specialResult);
        })
    });
});

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

Local testing

If you want to help us in developing webdriverjs, you can easily add mocha tests and run them locally:

npm install -g selenium-standalone http-server phantomjs

# start a local selenium instances
start-selenium

# serves the test directory holding the test files
http-server

# runs tests !
npm test

List of current helper methods

These are the current implemented helper methods. All methods take from 0 to a couple of parameters. Also all methods accept a callback so that we can assert values or have more logic when the callback is called.

addValue(String selector, String|String[] value, Function callback)
adds a value to an object found by a selector. You can also use unicode characters like Left arrow or Back space. You'll find all supported characters here. To do that, the value has to correspond to a key from the table.
call(callback)
call given function in async order of current command queue
chooseFile(String selector, String localFilePath, Function callback)
Given a selector corresponding to an <input type=file>, will upload the local file to the browser machine and fill the form accordingly. It does not submit the form for you.
clearElement(String selector, Function callback)
clear an element of text
click(String selector, Function callback)
Clicks on an element based on a selector.
close([String tab ID to focus on,] Function callback)
Close the current window (optional: and switch focus to opended tab)

Delete a cookie for current page.
doubleClick(String selector, Function callback)

drag(String selector, Number startX, Number startY, Number endX, Number endY, Number touchCount, Number duration, Function callback)
Perform a drag on the screen or an element (works only on Appium)
dragAndDrop(String sourceCssSelector, String destinationCssSelector, Function callback)
