Selenium and NUnit framework:
Integration of selenium with NUnit framework allows a tester to differentiate between various test classes. NUnit also allows testers to use annotations such as SetUp, Test, and TearDown to perform actions before and after running the test.
NUnit framework can be integrated with Selenium by creating a NUnit test class and running the test class using NUnit framework.
The below are the steps needed to create and run a test class using NUnit framework.
Steps to create a NUnit Test class in Selenium:
Step 1) In the Solution Explorer, Right click on project > Add > Class

To resolve this Got to Project > Properties and change Output Type to 'Class Library.' The default is 'Console Application.'
Step 5) Once the build is successful, we need to open the Test Explorer window. Click on Test -> Windows -> Test Explorer
Step 6) Test Explorer window opens with the list of available tests. Right-click on Test Explorer and select Run Selected Tests
Step 7) Selenium must open the browser with specified URL and close the browser. Test case status will be changed to 'Pass' on the Test Explorer window.
Selenium WebDriver Commands in C#:
C# uses the interface 'IWebDriver' for browser interactions. The following are the category of commands available in C#.
Let's study them one by one
Browser commands:The following are the list of browser commands available in C#.
Webelement Commands:
A Webelement represents all the elements on a web page. They are represented by HTML tags. Each of the buttons, textboxes, links, images, tables, and frames fall under Webelements. Operations on web elements can be triggered using the IWebelement interface. To interact with a Webelement, we need to find the element on the webpage and then perform operations on it. Tools like Firebug and Firepath can be used to identify the Xpath of Webelement.
The following are the list of Webelement commands available in C#.
Dropdown Commands:
Dropdown operations in C# can be achieved using the SelectElement class.
The following are the various dropdown operations available in C#.
