Selenium C# finding alert and verifying text

I am looking for an example for a verification that a javascript alert has taken place. I have a script that goes to a login page, and attempts to login to the system. I have a test case for a successful login, and I am trying to work on a failed login case. Any suggestions for automation best practices would be appreciated. So to boil my question down it is simply "How to I verify that this alert has happened on my webpage?"

HTML

<div class="alert">
The username and/or password entered are invalid.</div>

Test

    [Test]
    public void failedCustomerLogin()
    {
        //Finding the customer login link and clicking it
        var customerLogin = driver.FindElement(By.Id("Homepage_r2_c14"));
        customerLogin.Click();

        Assert.AreEqual("http://stage.blank.net/login", driver.Url);

        var userName = driver.FindElement(By.Id("username"));
        userName.SendKeys("badCustomerName");

        var Pasw = driver.FindElement(By.Id("password"));
        Pasw.SendKeys("BadPassword");

        var submit = driver.FindElement(By.Id("btnSubmit"));
        submit.Click();

        //TODO: need to find failed method
        string errorText = driver.SwitchTo().Alert().Text;
        Assert.IsTrue(errorText.Contains("The username and/or password entered are invalid."));
    }

Wait Selenium

        //Waiting for error to display
        driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(60));

This is the code that actually worked for the given alert, as Saifur pointed out the alert isn't really an alert. I was able to dig down to the class level and verify that the text appears on screen with the following code.

        var errorMessage = driver.FindElement(By.XPath("//div[contains(@class, 'alert')]"));
        Assert.IsTrue(driver.PageSource.Contains("The username and/or password entered are invalid."));

Try the following and assert if the expected text exists depending on the Testing framework and assertions you use.

string text = Driver.SwitchTo().Alert().Text;

I use NUnit assertion and in my case it looks like the following

string text = Driver.SwitchTo().Alert().Text;

Assert.IsTrue(text.Contains("The username and/or password entered are invalid."));

2nd edit: adding explicit wait

Try adding explicit wait

Driver.FindElement(By.TagName("test")).Click();

//Make sure the click above generates the alert
String text = (new WebDriverWait(Driver, TimeSpan.FromSeconds(10))).Until(d => d.SwitchTo().Alert().Text);
Assert.IsTrue(text.Contains("The username and/or password entered are invalid."));
