#wd-tractor

A port of Protractor to the wd driver.

Credits

  • Thanks to the Protractor project. A lot of ideas and code have been lifted from there.

Install

npm install wd-tractor

You also need to have Selenium running, or use Saucelabs.

Choose your style

Promises

...

browser
  .init({browserName: 'chrome'})
  .get('http://www.angularjs.org')
  .elementByNgInput('yourName').type('Bozzo')
  .elementByNgBinding('{{yourName}}')
    .text().should.become('Hello Bozzo!')
  .get('http://www.angularjs.org')
  .elementByNgRepeaterRow('todo in todos', 2)
    .text().should.become('build an angular app')
  .quit()
  .done();

Regular async code

...

async.waterfall([
  function(done) { browser.init({browserName: 'chrome'}, done); },
  function(session, done) { browser.get('http://www.angularjs.org', done );},
  // Displaying your name
  function(done) { browser.elementByNgInput('yourName', done);},
  function(input ,done) { input.type('Bozzo', done); },
  function(done) { browser.elementByNgBinding('{{yourName}}', done );},
  function(name, done) { name.text(done); },
  function(name, done) { name.should.equal('Hello Bozzo!'); done(); },
  // Getting todo list
  function(done) { browser.get('http://www.angularjs.org', done );},
  function(done) {
    browser.elementByNgRepeaterRow('todo in todos', 2, done);
  }, function(todo, done) { todo.text(done); },
  function(todo, done) { todo.should.equal('build an angular app'); done(); },
], function(err) {
  if(err) {throw err;}
  browser.quit();
});

Tests

  • Start Selenium with Chromedriver
  • Start the test app cd testapp && node ./scripts/web-server.js
  • mocha test

Todo

  • Add debugging functionality.
