Qunit tests are not working on visual studio 2012 as they work on browser

I have developed an SPA application using knockout and breeze, I have been using qunitJS for unit testing which works well on browser for my project. Recently I have found a plugin "Chutzpah" for VS2012, which can work well for testing qunit, which can check the test cases and respond for the Test though I am using breeze my test cases includes:

Creating, Deleting, Modifying entities on client side

Save changes on server side using breeze controller to SQLServer

Here the problem is the breeze test cases fails when I am testing in Chutzpah because they are not getting client side information like(Metadata/ ControllerMethods) which is called by the browser through the url defined in Breezeconfig. My question is that how can we perform unit test on breeze on server side like real unit test cases do. Suggestions for using new plugins or libraries which can actually make me do the unit testing of breeze are welcome

Here is the snippet for my testing project:

 asyncTest("can save nothing", function () {
  expect(1);
  newEm().saveChanges()
      .then(function(saveResult) {
          equal(saveResult.entities.length, 0, 'succeeded in saving nothing');
      })
      .catch(handleFail).finally(start);
});

asyncTest("can save a new Customer entity", function () {
  expect(1);

    // Create and initialize entity to save
    var em = newEm();
    var customer = em.createEntity('Customer', {
        CustomerID: newGuidComb(),
        CompanyName: 'Test1 ' + new Date().toISOString()
    });

    em.saveChanges()
        .then(function (saveResults) {
            ok(!!saveResults.entities[0], ' should have saved new Customer with CustomerID ' +
                customer.getProperty('CustomerID'));
        })
        .catch(handleFail).finally(start);
});

asyncTest("can modify my own Customer entity", function () {
    expect(2);
    var timestamp = new Date().toISOString();
    var em = newEm();

    var customer = em.createEntity('Customer', {
        CustomerID: newGuidComb(),
        CompanyName: "Test2A " + timestamp
    });

    em.saveChanges().then(modifyCustomer).fail(handleSaveFailed).fin(start);

    function modifyCustomer(saveResults) {
        var saved = saveResults.entities[0];
        ok(saved && saved === customer,
            "save of added customer should have succeeded");
        customer.CompanyName("Test2M " + timestamp);
        return em.saveChanges()
        .then(confirmCustomerSaved);
    }

    function confirmCustomerSaved(saveResults) {
        var saved = saveResults.entities[0];
        ok(saved && saved === customer,
            "save of modified customer, '{0}', should have succeeded"
            .format(saved && saved.CompanyName()));
    }

});
