## Writing a test!

<pre>
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();
          });
        });
      });
    });
  });
});
</pre>

## Promises Api

A promise api using [q](https://github.com/kriskowal/q) is
available. Code sample is
[here](https://github.com/admc/wd/blob/master/examples/example.promise.chrome.js).

## Chain Api

A chain api is also available. Code sample is [here](https://github.com/admc/wd/blob/master/examples/example.chain.chrome.js).

### Injecting command to the chain

As [queue](https://github.com/caolan/async#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

```javascript
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 codnitions in your script
    browser.clickElement(el, function() {
      console.log("did the click!");
    });
  })
  // ...
```

#### Example 2 - solution, use *next*

```javascript
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!");
    });
  })
  // ...
```

## JsonWireProtocol mapping

[supported mapping](https://github.com/admc/wd/blob/master/doc/jsonwire-mapping.md)

[full mapping](https://github.com/admc/wd/blob/master/doc/jsonwire-full-mapping.md)

## More docs!
<pre>
WD is simply implementing the Selenium JsonWireProtocol, for more details see the official docs:
 - <a href="http://code.google.com/p/selenium/wiki/JsonWireProtocol">http://code.google.com/p/selenium/wiki/JsonWireProtocol</a>
</pre>

## Run the tests!
<pre>
  - Install the Selenium server and Chromedriver
      node_modules/.bin/install_selenium
      node_modules/.bin/install_chromedriver
  - Run the selenium server with chromedriver:
      node_modules/.bin/start_selenium_with_chromedriver
  - cd wd
  - npm install .
  - make test
  - look at the results!
</pre>

## Run the tests on Sauce Labs cloud!
<pre>
  - cd wd
  - npm install .
  - make test_saucelabs
</pre>

## 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](https://github.com/visionmedia/dox).

To update the mappings run the following commands:

<pre>
  - make mapping > doc/jsonwire-mapping.md
  - make full_mapping > doc/jsonwire-full-mapping.md
</pre>

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