Selenium

 Automate web application using selenium

1.Add unit test project in Visual Studio 

2.Add NuGet packages 

Right click on the project name (Ex: MyTestProject) under Solution Explorer and click on Manage NuGet Package 

 

Figure 1 

Type the Selenium under Browse tab and search, then select Selenium.WebDriver and install 

 

Figure 2

Figure 3 

Same way add following NuGet package

Selenium.Support 

3.Let’s automate google search 

Write the test method as follow, 

   [TestMethod] 

Line 1   public void TestMethod1() 

Line 2   { 

Line 3      var Driver = new ChromeDriver(); 

Line 4      Driver.Navigate().GoToUrl("https://www.google.com/"); 

Line 5      Driver.Manage().Window.Maximize();    

Line 6      Driver.FindElementByName("q").SendKeys("Hello"); 

Line 7   } 

Line 3 

First it will initialize the Chrome web driver which can be used to load the web URL. 

Line 4  

Load the google.com url 

Line 5 

Maximums the web browser 

Line 6  

Type the test in search text box 

In C# test project we can have TestInitialize() attribute to initialize the test case and TestCleanup() to close the driver. See example below

FindElements Commands in C# 

Driver.FindElementById("Id"); 

Driver.FindElementByClassName("ClassName"); 

Driver.FindElementByCssSelector("CssSelector"); 

Driver.FindElementByLinkText("LinkTest"); 

Driver.FindElementByName("Name"); 

Driver.FindElementByPartialLinkText("PartialLinkTest"); 

Driver.FindElementByTagName("Name"); 

Driver.FindElementByXPath("Xpath"); 

  

Ex: 

 

Figure 5 

Above html code we can see the button attribut as below 

ID = submit 

Name = submit 

Class = btn 

So, our find element can as below 

Driver.FindElementById("submit"); 

Driver.FindElementByClassName("btn"); 

Driver.FindElementByName("submit"); 

5.How to find XPath in chrome. 

Right click on the element (Google search box) that you want to find the element. 

 

Then right click on the element code and go to Copy >> Copy XPath 

 

Then your Xpath will as below, 

//*[@id="q"] 

Driver.FindElementByXPath("//*[@id=’q’]");
