Usage

): wd shell
> x = wd.remote() or wd.remote("ondemand.saucelabs.com", 80, "username", "apikey")

> x.init() or x.init({desired capabilities override})
> x.get("http://www.url.com")
> x.eval("window.location.href", function(e, o) { console.log(o) })
> x.quit()

Writing a test!

var wd = require('wd')
  , assert = require('assert')
  , colors = require('colors')
  , browser = wd.remote();

browser.on('status', function(info) {
  console.log(info.cyan);
});

browser.on('command', function(meth, path, data) {
  console.log(' > ' + meth.yellow, path.grey, data || '');
});

browser.init({
    browserName:'chrome'
    , tags : ["examples"]
    , name: "This is an example test"
  }, function() {

  browser.get("http://admc.io/wd/test-pages/guinea-pig.html", function() {
    browser.title(function(err, title) {
      assert.ok(~title.indexOf('I am a page title - Sauce Labs'), 'Wrong title!');
      browser.elementById('i am a link', function(err, el) {
        browser.clickElement(el, function() {
          browser.eval("window.location.href", function(err, href) {
            assert.ok(~href.indexOf('guinea-pig2'));
            browser.quit();
          });
        });
      });
    });
  });
});

Browser initialization

Indexed parameters

var browser = wd.remote();
// or
var browser = wd.remote('localhost');
// or
var browser = wd.remote('localhost', 8888);
// or
var browser = wd.remote("ondemand.saucelabs.com", 80, "username", "apikey");

Named parameters

The parameters used are similar to those in the url module.

var browser = wd.remote()
// or
var browser = wd.remote({
  hostname: '127.0.0.1',
  port: 4444,
  user: 'username',
  pwd: 'password',
});
// or
var browser = wd.remote({
  hostname: '127.0.0.1',
  port: 4444,
  auth: 'username:password',
});

The following parameters may also be used (as in earlier versions):

var browser = wd.remote({
  host: '127.0.0.1',
  port: 4444,
  username: 'username',
  accessKey: 'password',
});

Url string

var browser = wd.remote('http://localhost:4444/wd/hub');
// or
var browser = wd.remote('http://user:[email protected]/wd/hub');

Url object created via url.parse

URL module documentation

var url = require('url');
var browser = wd.remote(url.parse('http://localhost:4444/wd/hub'));
// or
var browser = wd.remote(url.parse('http://user:[email protected]:80/wd/hub'));

Defaults

{
    protocol: 'http:'
    hostname: '127.0.0.1',
    port: '4444'
    path: '/wd/hub'
}

Environment variables for Saucelabs

When connecting to Saucelabs, the user and pwd fields can also be set through the SAUCE_USERNAME and SAUCE_ACCESS_KEY environment variables.

Promises Api

A promise api using q is available. Code sample is here.

Generators Api

Yiewd is a wrapper around Wd.js that uses generators in order to avoid nested callbacks, like so:

wd.remote(function*() {
  yield this.init(desiredCaps);
  yield this.get("http://mysite.com");
  el = yield this.elementById("someId");
  yield el.click();
  el2 = yield this.elementById("anotherThing")
  text = yield el2.text();
  text.should.equal("What the text should be");
  yield this.quit();
});

Chain Api

A chain api is also available. Code sample is here.

Injecting command to the chain

As queue implementation that we're using has some limitations, a special helper method next was added. It allows you to inject new calls to the execution chain inside callbacks.

Example 1 - the problem

browser
  .chain()
  // ...
  .elementById('i am a link', function(err, el) {
    // following call will be executed apart from the current execution chain
    // you won't be able to pass results further in chain
    // and it may cause racing conditions in your script
    browser.clickElement(el, function() {
      console.log("did the click!");
    });
  })
  // ...

Example 2 - solution, use next

browser
  .chain()
  // ...
  .elementById('i am a link', function(err, el) {
    // call to clickElement will be injected to the queue
    // and will be executed sequentially after current function finishes
    browser.next('clickElement', el, function() {
      console.log("did the click!");
    });
  })
  // ...

Inserting async code with queueAddAsync

browser
  .chain()
  // ...
  .elementById('i am a link', function(err, el) {
    // following call will be executed apart from the current execution chain
    // you won't be able to pass results further in chain
    // and it may cause racing conditions in your script
  })
  .queueAddAsync( function(cb) {
    // your code here
    cb(null);
  })
  .clickElement(el, function() {
    console.log("did the click!");
  })
  // ...

Monkey patching

You may want to monkey patch the webdriver class in order to add custom functionalities. There is an example here.

Adding new method / Contributing

If the method you want to use is not yet implemented, that should be easy to add it to lib/webdriver.js. You can use the doubleclick method as a template for methods not returning data, and getOrientation for methods which returns data. No need to modify README as the doc generation is automated. Other contributions are welcomed.

Doc

The JsonWire mappings in the README and mapping files are generated from code comments using dox.

To update the mappings run the following commands:

  - make mapping > doc/jsonwire-mapping.md
  - make full_mapping > doc/jsonwire-full-mapping.md
  - make unsupported_mapping > doc/jsonwire-unsupported-mapping.md

The content of doc/jsonwire-mapping.md should then be manually integrated into README.md.

Safe Methods

The safeExecute and safeEval methods are equivalent to execute and eval but the code is executed within a eval block. They are safe in the sense that eventual code syntax issues are tackled earlier returning as syntax error and avoiding browser hanging in some cases.

An example below of expression hanging Chrome:

browser.eval("wrong!!!", function(err, res) { // hangs
browser.safeEval("wrong!!!", function(err, res) { // returns
browser.execute("wrong!!!", function(err, res) { //hangs
browser.safeExecute("wrong!!!", function(err, res) { //returns
