Unit Testing and Test Automation in VS2012 Part 2: Integrating Selenium with Visual Studio

4 Jul

In the first part of this series we discussed about integrating NUnit with Visual Studio 2012. One of NUnit’s strong points is its extensibility which has been used to expand unit testing even further — as far up as the user interface in fact. This is where Selenium comes in.

Selenium runs on top of NUnit so that it can run tests against instances of web browsers. With the new testing features of Visual Studio 2012 we can now use it to test web applications.

If you haven’t read the first part of this series and haven’t followed the steps given there, I suggest reading it now and following the steps to install NUnit on Visual Studio 2012 first. They are a prerequisite to the next steps in this article.

Integating Selenium into Visual Studio 2012

Since we’ve already integrated NUnit to our Visual Studio solution, why not go all the way and use Selenium as well? Selenium uses the NUnit Framework for its tests anyway — it’s just a matter of adding several more components to allow Selenium’s Webdriver to fire up a web browser and start executing tests.

To do this we need to extend our project a bit:

  1. Open up the Manage NuGet Packages window again (right-click on References under the project -> Manage NuGet Packages) and in the search box type “Selenium”
  2. Select “Selenium Webdriver” and click Install to add Selenium references to your project.
  3. Select “Selenium Webdriver Support Classes” and click Install — these are some additional references necessary to run Selenium tests in your Visual Studio solution.
  4. Download IE Webdriver from the Selenium download page (choose the appropriate 32 or 64 bit version) and unzip.
  5. Righ-click on the project name and click “Add existing item…”
  6. Browse to the folder containing IEDriverServer.exe and choose that file to add to the project
  7. Under the project tree right-click on the file and click Properties
  8. Set the value of the field “Copy to Output Directory” to “Copy if newer”

The steps regarding the web driver ensure that the exe required to open up a browser is always copied to the /bin/Debug folder, from where it will in turn be used to call on the browser executables and open up the browser.

We can use the project we already set up above to test this. Add a new class and set it to have the following code. Note the additional OpenQA using declarations, aside from the NUnit.Framework that we’ve used before:

{

    public class Driver
    {
        IWebDriver driver;
        [SetUp]
        public void Setup()
        {
            // Create a new instance of the Firefox driver
            driver = new InternetExplorerDriver();
        }
        [TearDown]
        public void Teardown()
        {
            driver.Quit();
        }
        [Test]
        public void GoogleSearch()
        {
            //Navigate to the site
            driver.Navigate().GoToUrl("http://www.google.com");
            // Find the text input element by its name
            IWebElement query = driver.FindElement(By.Name("q"));
 
            // Enter something to search for
            query.SendKeys("Selenium");
 
            // Now submit the form
            query.Submit();
 
            // Google's search is rendered dynamically with JavaScript.
            // Wait for the page to load, timeout after 5 seconds
            WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5));
            wait.Until((d) => { return d.Title.StartsWith("selenium"); });
 
            //Check that the Title is what we are expecting
            Assert.AreEqual("selenium - Google Search", driver.Title);
        }
    }
}

Run the tests again. The test should open Internet Explorer and then open up Google. The result in the Test Explorer would look like this, just like our NUnit test:

Conclusion

With the capability to tightly integrate NUnit and Selenium in Visual Studio 2012 solutions and projects, Microsoft redeems itself by rectifying the ghosts of MSTest: it brings unit testing much closer to coding, it finally allows test-first/test driven development, and it opens up the capability for third-party unit testing frameworks to run in Visual Studio as first class citizens. This allows other open source testing frameworks like xUnit.net, QUnit/Jasmine, and MbUnit to run seamlessly with Visual Studio 2012.

I’d like to point out Anoop Shetty’s blog post on Selenium integration from which I took the steps and code for the Selenium test used in this post. While his post was applicable to Visual Studio 2010 the steps were practically the same for Visual Studio 2012.

How to write effective GUI test automation code using Selenium and Java

12 Jun

Just searching on Internet and got this document. In this presentation, you can get some useful information about how to write effective GUI test automation code using Selenium and Java

1. Introduction: What’s Selenium
2. What we achieved
3. 7 good practices using Capture Replay Tools

– GUI element repository.

– Division of data and script.
– Model the test objects.
– Establish standard functions and methods using “speaking” names.
– Central management of environment information.
– Divide common from project specific stuff. Use layering.
– Generate a useful test report
4. What’s missing in Selenium and how we closed the gap
5. Forecast

Experiences of Test Automation – Case studies of Software Test Automation

31 May

Software test automation has moved beyond a luxury to become a necessity. Applications and systems have grown ever larger and more complex, and manual testing simply cannot keep up. As technology changes, and more organizations move into agile development, testing must adapt—and quickly. Test automation is essential, but poor automation is wasteful—how do you know where your efforts will take you?

Authors Dorothy Graham and Mark Fewster wrote the field’s seminal text, Software Test Automation, which has guided many organizations toward success. Now, in Experiences of Test Automation, they reveal test automation at work in a wide spectrum of organizations and projects, from complex government systems to medical devices, SAP business process development to Android mobile apps and cloud migrations. This book addresses both management and technical issues, describing failures and successes, brilliant ideas and disastrous decisions and, above all, offers specific lessons you can use.

Coverage includes
Test automation in agile development
How management support can make or break successful automation
The importance of a good testware architecture and abstraction levels
Measuring benefits and Return on Investment (ROI)
Management issues, including skills, planning, scope, and expectations
Model-Based Testing (MBT), monkey testing, and exploratory test automation
The importance of standards, communication, documentation, and flexibility in enterprise-wide automation
Automating support activities
Which tests to automate, and what not to automate
Hidden costs of automation: maintenance and failure analysis
The right objectives for test automation: why “finding bugs” may not be a good objective
Highlights, consisting of lessons learned, good points, and helpful tips

Experiences of Test Automation will be invaluable to everyone considering, implementing, using, or managing test automation. Testers, analysts, developers, automators and automation architects, test managers, project managers, QA professionals, and technical directors will all benefit from reading this book.

You can get this book with sample (only chapter 29. Test Automat ion Anecdote s is available )  in here
