JavaScript unit test tools for TDD

Question

I ve looked into and considered many JavaScript unit tests and testing tools  but have been unable to find a suitable option to remain fully TDD compliant  So  is there a JavaScript unit test tool that is fully TDD compliant

BusterJS

There is also BusterJS from Christian Johansen, the author of Test Driven Javascript Development and the Sinon framework. From the site:

Buster.JS is a new JavaScript testing framework. It does browser testing by automating test runs in actual browsers (think JsTestDriver), as well as Node.js testing.

You should have a look at env js  See my blog for an example how to write unit tests with env js

We added JUnit integration to our Java to Javascript code generator ST-JS (http://st-js.org). The framework generates to corresponding Javascript for both the tested code and the unit tests and sends the code to different browsers.

There is no need for a separate server as the unit test runner opens the needed http port (and closes it once the tests finished). The framework manipulates the Java stacktrace so that the failed asserts are correctly displayed by the JUnit Eclipse plugin. Here is a simple example with jQuery and Mockjax:

@RunWith(STJSTestDriverRunner.class)
@HTMLFixture("<div id='fortune'></div>")

@Scripts({ "classpath://jquery.js",
       "classpath://jquery.mockjax.js", "classpath://json2.js" })
public class MockjaxExampleTest {
  @Test
  public void myTest() {
    $.ajaxSetup($map("async", false));
    $.mockjax(new MockjaxOptions() {
      {
        url = "/restful/fortune";
        responseText = new Fortune() {
          {
            status = "success";
            fortune = "Are you a turtle?";
          }
        };
      }
    });

    $.getJSON("/restful/fortune", null, new Callback3<Fortune, String, JQueryXHR>() {
      @Override
      public void $invoke(Fortune response, String p2, JQueryXHR p3) {
        if (response.status.equals("success")) {
          $("#fortune").html("Your fortune is: " + response.fortune);
        } else {
          $("#fortune").html("Things do not look good, no fortune was told");
        }

      }
    });
    assertEquals("Your fortune is: Are you a turtle?", $("#fortune").html());
  }

  private static class Fortune {
    public String status;
    public String fortune;
  }
}

You might also be interested in the unit testing framework that is part of qooxdoo, an open source RIA framework similar to Dojo, ExtJS, etc. but with quite a comprehensive tool chain.

Try the online version of the testrunner. Hint: hit the gray arrow at the top left (should be made more obvious). It's a "play" button that runs the selected tests.

To find out more about the JS classes that let you define your unit tests, see the online API viewer.
