Automated asp.net web application testing using Selenium

ASP.Net Web Application Integration testing using Selenium 2.0

Selenium primarily used for automating web applications for testing purposes. You can create browser based regression tests using Selenium WebDriver. 

Selenium WebDriver provides a concise programming interface. It drives the browser much more effectively. Selenium WebDriver makes direct calls to browser using each browser's native support for automation. 

This articles deals with running tests against the application all running on the same machine. WebDriver will run the browser directly. *This article doesn't cover test distribution over multiple machine*. The article covers running tests for IE browser.

Setup:

To create and run Selenium tests using IE or chrome browser, we need to set up and reference few things before we hit the ground running.

Note: Following instructions are specific to IE browser.

DriverServer Setup:

1) Based on your computer architecture, please download 32bit or 64 bit IEDriverServer from here.

2) UnZip the contents of download and you can run the Driver in the two ways

                       a) Designate Driver.exe as part of your Test project test settings as deployable item so it                                    copied to test project output every time you run the tests

                        b) Instead, set the IEDriverServer.Exe path as part of PATH environment variable.

 3) The point is IEDriverServer should be running when executing tests using selenium

Assembly References in VS2012:

1) Please download the latest version of Selenium-dotnet-(version).zip which includes .Net bindings and            WebDriver programming API from here

2) UnZip the contents of download and reference the "WebDriver.dll" based on your target .net Framework      to your testing project as shown below.

3) You're all set now

Running the tests:

Following are the simple tests designed for a pseudo website with two pages. First test automates the login function and second test automates user details on the home page.

When you run the tests, you'll see IEDriverServer console running up and your sample site being run by Selenium in the web browser as shown below:

 second test results

namespace SeleniumAutomatedTests
{
    [TestClass]
    public class SeleniumUnitTests
    {
        private static InternetExplorerDriver _webDriver;

        [TestMethod]
        public void TestSiteLoginFunction()
        {
            //initialize internet explorer driver and you can set up options for driver 
            _webDriver = new InternetExplorerDriver(new InternetExplorerOptions()
            {
                InitialBrowserUrl = "http://localhost/TestSite/Login.aspx",
                
            });
            //find the desired elements by id, css class or name, xpath 
            _webDriver.FindElement((By.Id("userNameTxtBox"))).SendKeys("Selenium");
            _webDriver.FindElement(By.Id("passwordTxtBox")).SendKeys("selenium");

            var logInButton = _webDriver.FindElement(By.Id("signInBtn"));
            //simulating the button click
            logInButton.Click();

            //wait for 5 seconds for the page to load
            _webDriver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 5));

            var welcomeLabel = _webDriver.FindElement(By.Id("WelcomeLabel"));
            //interface to execute javascript code on the host page
            var js = (IJavaScriptExecutor) _webDriver;
            //you can also execute on fly javascript code or predefined javascript functions attached to host page.
            js.ExecuteScript("alert('you successfully signed in.')");
            //finally, some asserting
            Assert.IsNotNull(welcomeLabel.Text);
           
        }

        [TestMethod]
        public void TestHomePageSubmitFunction()
        {
            _webDriver = new InternetExplorerDriver();
            _webDriver.Navigate().GoToUrl("http://localhost/TestSite/Home.aspx");
            _webDriver.FindElement((By.Id("ageTxtBox"))).SendKeys("29");
            _webDriver.FindElement(By.Id("cityTxtBox")).SendKeys("Los Angeles");
            //submitting the form using selenium
            var form = _webDriver.FindElement(By.Id("detailsForm"));
           form.Submit();

            _webDriver.Manage().Timeouts().ImplicitlyWait(new TimeSpan(0, 0, 5));
            var welcomeLabel = _webDriver.FindElement(By.Id("WelcomeLabel"));
            Assert.IsTrue(welcomeLabel.Text.Contains("Los Angeles") && welcomeLabel.Text.Contains("29"));
        }


    }

   
}

Hope this helps..
