Complete Guide To Install Selenium Webdriver With C# with Visual Studio

Selenium is a portable software testing suite for web applications. Primarily, it is for automating web applications for testing purpose, but it certainly not limited to just that. Selenium is open source. Selenium is highly flexible. There are many ways you can add functionality to both Selenium test scripts and Selenium’s framework to customize your test automation i.e. We can modify the built-in selenium functions based on our requirement. This is perhaps Selenium’s greatest strength when compared with other automation tools. Selenium is a set of different software tools each with a different approach to supporting test automation. It has 4 components.

1. Selenium Integrated Development Environment (IDE).
2. Selenium Remote Control (RC).
3. Selenium WebDriver.
4. Selenium Grid.

Selenium Scripts can be written in any programming languages like C#, Groovy, Java, Perl, PHP, Python, Ruby, JavaScript. Selenium Scripts can run on any browser like Mozilla Firefox, Internet Explorer, Google Chrome, Microsoft Edge, Safari or Opera. Selenium Scripts can run on OS like Windows, Mac, Android or Linux.

1. Differences between Selenium with C# and Selenium with Java?

There is no Major differences between Selenium with Java and Selenium with C#.

Selenium with Java	Selenium with C#
In Selenium with Java we have WebDriver to create web browser instance.	In Selenium with C# we have IWebDriver to create web browser instance.
In Selenium with Java we use WebElement to find out web elements in the application.	In Selenium with C# we use IWebElement to find out web elements in the application.
In Selenium with Java we use @FindBy annotation is used in Page Objects in Selenium tests to specify the object location strategy for a WebElement or a list of WebElements.	In Selenium with C# we use [FindBy] annotation is used in Page Objects in Selenium tests to specify the object location strategy for a WebElement or a list of WebElements.

IDE used for C#

C# development can be done using many IDEs like Visual Studio, MonoDevelop, #develop, Rider and Many more. In this tutorial we will develop C# in Visual Studio.

2. Downloading Selenium via NuGet Package Manager.

  Let’s see installation of selenium with Visual studio by downloading via NuGet Package Manager with an example. Create C# project by using steps mentioned in Section 7. Step 1: Create a new project called FirstProgram using above mentioned steps.  Step 2: Navigate to Tools-> NuGet Package Manager-> Manager NuGet Packages for Solution…  Step 3: In next screen

1. Select Browse tab.
2. Enter Selenium in search field.
3. Selenium latest Selenium.WebDriver available.
4. Select the project created in step 1(i.e FirstProgram)
5. Click on Install.

Step 4: In next screen click on OK button.Step 5: Once WebDriver is installed. We should get following message.Step 6: Once WebDriver is installed let’s install ChromeDriver. Tools-> NuGet Package Manager-> Manager NuGet Packages for Solution…

1. Enter ChromeDriver in search field.
2. Select the ChromeDriver.
3. Select the project created.
4. Click on Install.

In Next screen click on OK button.Once ChromeDriver is installed. We will get the following message.  Step 7: Selenium is installed to FirstProgram. Now let’s write code to perform goggle search.Code Explanation.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

// Create a driver instance for chromedriver             IWebDriver driver = new ChromeDriver();             //Navigate to google page             driver.Navigate().GoToUrl("http:www.google.com");             //Maximize the window             driver.Manage().Window.Maximize();             //Find the Search text box using xpath             IWebElement element = driver.FindElement(By.XPath("//*[@title='Search']"));             //Enter some text in search text box             element.SendKeys("learn-automation");             //Close the browser             driver.Close();

Navigate to Start button on the top and click on it. It will launch console 1^st and after few seconds it will launch ChromeDriver and will perform action mentioned in the code.We will get output as shown below.
