Using Node.js for UI Testing

By: Pedro Teixeira

Overview of this book

<p>Automating tests for your user interfaces has always been the holy grail of programming. Now, using Zombie.js and Mocha you can create and quickly run your tests, allowing you to test even small changes. Increase your confidence in the code and minimize the number of times you have to use a real browser while you develop.</p> <p>"Using Node.js for UI Testing" is a quick and thorough guide on how to automatically test your web app, keeping it rock solid and bug-free. You will learn how to simulate complex user behaviour and verify that your application behaves correctly.</p> <p>You will create a web app in Node.js that uses complex user interactions and AJAX; by the end you will be able to fully test it from the command-line. Then you will start creating the user interface tests for this application using Mocha as a framework and Zombie.js as a headless browser.</p> <p>You will also create a complete test suite, module by module, testing simple and complex user interactions.</p>

Dumping the whole document


If at any time you need to inspect the entire contents of your document, you can inspect the return value of browser.html(). For instance, if you want to inspect the document's state right before the browser is reloaded, you can add the following line to the test/todo.js file, in place of browser.dump():

...
            browser.choose('Use Alarm', function(err) {
              if (err) throw err;

              assert.equal(container.style.display, '');

              browser.choose('No Alarm', function(err) {
                if (err) throw err;

                console.log(browser.html());

                assert.equal(container.style.display, 'none');

                done();
              });
            });
...

You can now run the test and observe the output:

$ node_modules/.bin/mocha -g 'alarm' test/todos
...
  <html style=""><head>
