Webdriver/selenium 2.0 javascript bindings for nodejs

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 webdriver with queued commands locally:

Run selenium server first:

java -jar selenium-server-standalone-2.11.0.jar

Then run this with nodejs:

var webdriverjs = require("webdriverjs");
var client = webdriverjs.remote();
//var client = webdriverjs.remote({host: "xx.xx.xx.xx"}); // to run it on a remote webdriver/selenium server
//var client = webdriverjs.remote({desiredCapabilities:{browserName:"chrome"}}); // to run in chrome

client
    .init()
    .url("https://github.com/")
    .getElementSize("id", "header", function(result){ console.log(result);  })
    .getTitle(function(title) { console.log(title) })
    .getElementCssProperty("id", "header", "color", function(result){ console.log(result);  })
    .end(); 

Submitting a form

To submit a form, pick any elemtn inside the form (or the form itself) and call .submitForm

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

client
    .init()
    .url("http://www.google.com")
    .setValue("#lst-ib", "webdriver")
    .submitForm("#tsf")
    .end();

More examples in the examples folder

Other options

To make webdriverjs be silent (omit all logs):

var client = require("webdriverjs").remote({logLevel: 'silent'}); // if you use it as part of other app and the logs arent interesting

client
    .init()
    .url("https://github.com/")
    .getTitle(
        function(result)
        {
            console.log(result)
        }
    )
    .end();

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(urlResult)
        {
            this.getTitle(
                function(titleResult)
                {
                    var specialResult = {url: urlResult.value, title: titleResult};
                    if (typeof callback == "function")
                    {
                        callback(specialResult);
                    }
                }
            )
        }
    );
});

client
    .init()
    .url("http://www.google.com")
    .getUrlAndTitle(function(result)
    {
        console.log(result);
    })
    .end();

Example of using webdriverjs for testing locally

Run selenium server first:

java -jar selenium-server-standalone-2.5.0.jar

Then run this with nodjs:

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

client
    .testMode()
    .init()
    .url("https://github.com")
    .tests.cssPropertyEquals(".login a", "color", "#4183c4", "Color of .login a is #4183c4")
    .tests.titleEquals("Secure source code hosting and collaborative development - GitHub", "Title of the page is 'Secure source code hosting and collaborative development - GitHub'")
    .click(".pricing a")
    .tests.titleEquals("Plans & Pricing - GitHub", "Title of the page is 'Plans & Pricing - GitHub'")
    .tests.visible(".pagehead", true, ".pagehead is visible after click")
    .end();

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.

  • dragAndDrop(sourceCssSelector, destinationCssSelector, [callback]) - Drags an item to a destination
  • click(css selector, [callback]) - Clicks on an element based on a css selector
  • doubleClick(css selector, [callback]) - Clicks on an element based on a css selector
  • end([callback]) - Ends a sessions (closes the browser)
  • getAttribute(css selector, attribute name, [callback]) - Get an attribute from an dom obj based on the css selector and attribute name
  • getCssProperty(css selector, css property name, [callback]) - Gets a css property from a dom object selected with a css selector
  • getElementCssProperty(find by, finder, css property name, [callback]) - Gets a css property from a dom object selected with one of the base selecting mechanisms in the webdriver protocol (class name, css selector, id, name, link text, partial link text, tag name, xpath)
  • getElementSize(css selector, [callback]) - Get the elements size. The element is found with a css selector
  • getLocation(css selector, [callback]) - Gets the x and y coordinate for an object based on the css selector
  • getLocationInView(css selector, [callback]) - Gets the x and y coordinate for an object based on the css selector in the view
  • getSize(css selector, [callback]) - Gets the width and height for an object based on the css selector
  • getText(css selector, [callback]) - Gets the text content from a dom obj found by the css selector
  • getTagName(css selector, [callback]) - Gets the tag name of a dom obj found by the css selector
  • getTitle([callback]) - Gets the title of the page
  • getSource([callback]) - Gets source code of the page
  • getValue(css selector, [callback]) - Gets the value of a dom obj found by css selector
  • isVisible(css selector, [callback]) - Return true or false if the selected dom obj is visible (found by css selector)
  • isSelected(css selector, [callback]) - Return true or false if an OPTION element, or an INPUT element of type checkbox or radiobutton is currently selected (found by css selector).
  • moveToObject(css selector, [callback]) - Moves the page to the selected dom object
  • pause(milliseconds, [callback]) - Pauses the commands by the provided milliseconds
  • saveScreenshot(path to file, [callback]) - Saves a screenshot as a png from the current state of the browser
  • setValue(css selector, value, [callback]) - Sets a value to an object found by a css selector
  • submitForm(css selector, [callback]) - Submits a form found by the css selector
  • waitFor(css selector, milliseconds, [callback]) - Waits for an object in the dom (selected by css selector) for the amount of milliseconds provided. the callback is called with false if the object isnt found.
  • buttonClick(css selector, [callback]) - click on a button using a css selector
  • clearElement(css selector, [callback]) - clear an element of text

List of current implemented wire protocol bindings

Here are the implemented bindings (and links to the official json protocol binding)

FAQ

Which protocol parts are done?

Well, not all of them but a couple and more to come.

Are there more things than "just the protocol"?

Yes, the implementation is done so that more complicated sets of protocol elements can be chained. I will explain more about this soon
