Usage

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

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

Writing a test!

var webdriver = require('wd')
  , assert = require('assert');

var browser = webdriver.remote();

browser.on('status', function(info){
  console.log('\x1b[36m%s\x1b[0m', info);
});
browser.on('command', function(meth, path){
  console.log(' > \x1b[33m%s\x1b[0m: %s', meth, path);
});

desired = {
  browserName:'chrome'
  , tags: ["examples"]
  , name: "This is an example test"
};

browser.init(desired, 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, location) {
            assert.ok(~location.indexOf('guinea-pig2'));
            browser.quit();
          });
        });
      });
    });
  });
});

More docs!

WD is simply implementing the Selenium JsonWireProtocol, for more details see the official docs:
 - http://code.google.com/p/selenium/wiki/JsonWireProtocol

Run the tests!

  - Run the selenium server with chromedriver:
      java -jar selenium-server-standalone-2.21.0.jar -Dwebdriver.chrome.driver=<PATH>/chromedriver
  - cd wd
  - npm install .
  - make test
  - look at the results!

Run the tests on Sauce Labs cloud!

  - cd wd
  - npm install .
  - make test_saucelabs

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

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