A simple test file failed with JUTE and here is the output:

This XML file does not appear to have any style information associated with it. The document tree is shown below.


Test Timed Out: Most likely a Javascript parsing error - try loading /test/simple.html in your browser

Just opening the test page works fine:

And here is the test page:

Simple Test 1

        var suite = new Y.Test.Suite("Simple Suite");
        suite.add(new Y.Test.Case({
            testSomething: function() {
                Y.Assert.areEqual("1", "1", "failed - different");
            }
        }));

        Y.Test.Runner.add(suite);
        Y.Test.Runner.run();
    });
