Cannot run multiple test case class through PyUnit in Eclipse

[pittip]

I have 2 classes in python and both of them extend the unittest.TestCase class. Hence I have 2 test cases. These test cases (classes) are:

class Test_ID_94017(unittest.TestCase):
    ex = Excel()

    def setUp(self):
        self.driver = Browser().createBrowserDriver()
        self.driver.maximize_window()
        self.driver.implicitly_wait(15)
        self.ex.setUpASheetInExcel('Login')

    def test_CCPD_Regression001_PER_Custom_Check(self):
        ccp = CCPLogin(self.driver)
        loginDetails = self.ex.getLoginDetailsForATestCaseFromExcel('Login', '94017')
        ccp.login(loginDetails[0], loginDetails[1], loginDetails[2])

        wait = WebDriverWait(self.driver, 20)

        wait.until(lambda driver:self.driver.title.startswith('Harland Clarke'))
        self.assertIn("Harland Clarke Checks Online Catalog", self.driver.title, "Failed on CHECKS ONLINE CATALOG PAGE")

        Home().clickOrderButton(self.driver)
        PersonalHurdle().clickProceedWithNoChangeLink(self.driver)
        pc = ProductConfig()
        pc.confirmAddress(self.driver, False)
        pc.clickContinueButton(self.driver)

        wait.until(lambda driver:self.driver.title.startswith('Customize Your Check'))     
        self.assertIn("Customize Your Check", self.driver.title)

        try:
            updateButtonHidden = self.driver.find_element_by_xpath(CustomizeYourCheckPage.UPDATE_BUTTON)
            self.assertIn("hidden", updateButtonHidden.get_attribute('style'))
        except NoSuchElementException:
            assert 0, "Can't find hidden button"

        self.driver.find_element_by_xpath(CustomizeYourCheckPage.SECOND_FONT).click()
        updateButtonVisible = self.driver.find_element_by_xpath(CustomizeYourCheckPage.UPDATE_BUTTON)

        self.assertIn("visible", updateButtonVisible.get_attribute('style'))

        CustomizeYourCheck().clickAddToCartButton(self.driver)
        time.sleep(5)
        OrderExtraTodayPopup().clickNoThanksButton(self.driver)

        wait.until(lambda driver:self.driver.title.startswith('Shopping Cart'))
        assert "Shopping Cart" in self.driver.title

        sc = ShoppingCart()
        sc.selectItemQuantity(self.driver)
        sc.clickProceedToCheckoutButton(self.driver)

        wait.until(lambda driver:self.driver.title.startswith('Checkout'))
        self.assertIn("Checkout", self.driver.title)

        wait.until(lambda driver:self.driver.find_element_by_xpath(CheckoutStep1Page.SELECT_SHIPPING_METHOD_LINK).is_displayed())
        self.driver.find_element_by_xpath(CheckoutStep1Page.SELECT_SHIPPING_METHOD_LINK).click()

        time.sleep(10)

        ShippingMethod().selectAShippingMethod(self.driver)
        cs1 = CheckoutStep1()
        cs1.enterEmailAddress(self.driver, "[e-mail]")
        cs1.clickProceedToOrderSummary(self.driver)

        wait.until(lambda driver:self.driver.title.startswith('Order Summary'))
        self.assertIn("Order Summary", self.driver.title)

        OrderSummary().clickSubmitOrderButton(self.driver)

        wait.until(lambda driver:self.driver.title.startswith('Order Confirmation'))
        self.assertIn("Order Confirmation", self.driver.title)

        OrderConfirmation().clickLogoutLink(self.driver)

        wait.until(lambda driver:self.driver.find_element_by_css_selector(LogoutPopupWindow.YES_BUTTON).is_displayed())
        self.driver.find_element_by_css_selector(LogoutPopupWindow.YES_BUTTON).click()

**Problem is when I try to run it in Eclipse through PyUnit, only the first test case executes, passes and gives me the result. The second test case does not execute at all. I remember, it was executing both the test cases earlier but I'm not sure why it is not executing both of them now. Please advice. Need help here as I am blocked now!
***This is my first attempt at Daniweb and I am not sure if I am posting my doubt at the correct forum. Please bear with me*
