I have already posted Selenium WebDrier Tutorials posts how to setup web driver with eclipse and Run first test with webdriver, how to configure junit with eclipse to generate webdriver test report. We have also learn different methods of locating elements of software web application in webdriver. In this video we will discuss Selenium WebDriver with C#. Selenium is one of the most popular automation tool in market. Selenium with C# also has high deman. Selenium is a free automation testing tool for web applications. It is able to work with different browsers like Chrome, Firefox, IE, Opera and simulate human like behavior. Selenium is able to interact with all the different elements in a webpage. It can click on them, input text, extract text and much more.

What is Selenium?

Selenium is an open-source testing tool, which means it can be downloaded from the internet without spending anything. Selenium is a functional testing tool and also compatible with non-functional testing tools as well.

For further information about Selenium, refer the below link: https://www.javatpoint.com/selenium-tutorial

Why we use Selenium for automation testing?

Selenium is one of the most popular automation testing tools. Here automation testing is a process of converting any manual test case into the test scripts using automation tools such as Selenium.

Following are some aspects that, why we prefer Selenium for automation testing:

• The Selenium test scripts can be written in any programming languages like Java, Python, C#, Ruby, Perl, as so on.
• The Selenium test scripts can be executed in many operating system platforms such as Windows, Mac, Linux, etc.
• And the test scripts can be implemented on different browsers like Google Chrome, Mozilla Firefox, Internet Explorer, Safari, etc.
• The Selenium testing tool can be associated with other testing tools such as TestNG, Junit for managing the test cases, and generating test reports.
• To achieve continuous testing, Selenium is integrated with Maven, Jenkins, and Docker testing tools.

What is Python?

• Python supports the Object-Oriented Programming approach to establish the applications. It is simple and easy to learn and provides lots of high-level data structures. It is an open-source language.
• It is a high-level and interpreter scripting programing language.
• Python makes the development and debugging fastbecause there is no compilation step included in Python development.

For further details about Python language, refer the below link: https://www.javatpoint.com/Python-tutorial

Why is Python useful for automation testing?

• Python is very useful for automation testing because it supports multiple programming patterns.
• Python has many built-in testing frameworks such as Pytest and Robot, which covers the debugging and faster workflow.
• It is an interpreted language means the interpreter implements the code line by line at a time that's makes debugging easy.
• Python is Cross-platform Language; that's why it can run on different platforms like Windows, Linux, UNIX, and Macintosh,
• Python can be easily implemented with other programming languages such as C, C++, JAVA, etc.

Selenium with Python

There are two ways to run a Selenium test scripts with the help of Python:

1. Configure Selenium using Python
2. Configure PyDev in Eclipse.

Let us see how we configure Selenium with the help of Python programing language:

Configure Selenium using Python

There are following steps to configure Selenium using Python:

• Download and install Python on Windows
• Install Selenium libraries in Python
• Download and install PyCharm
• Create a new project and write the Selenium test script

• First, open the PyCharm by Double-click on it, and click on the Create New Project as we can see in the below image:

• After that, we will provide the project name as SeleniumTest, and click on the Create button as we can see in the below image:

• After clicking on the Create button, we will get the below window:

Adding Selenium Test Scripts

For adding the Selenium test scripts in the PyCharm, follow the below process:

• Right-click on the SeleniumTest project, then go to New, and we can add any of the options in the given list according to our requirements.
• But, here we are adding the Python file, so for this, we will add the Directory which helps us to manage them separately as we can see in the below screenshot:

• And, provide the Directory name, in our case we give it as Demo
• After that, press the Enter key as we can see in the below screenshot:

• After creating a Directory, we will right-click on the Demo Directory then go to New, and select Python File from the pop-up menu as we can see in the below image:
  Demo → New → Python File

• And, we provide a name to python file as Sample1.
• Then, press the Enter key as we can see in the below image:

• After that, we got the IDE where we can create or write our Selenium test Scripts.

Write the Selenium test script

For our testing purpose, we will first go to the Google Home page and search javatpoint from there.

We are creating our sample test script step by step to give you a complete understanding of how we write a Selenium test script in Python programming language.

Selenium Webdriver Tutorial Python

For this, follow the below steps:

Step1

In the first step, we will type the following statement to import the web driver:

Step2

After that, we will open the Google Chrome browser.

As we can see in the below screenshot, we have multiple types of browsers options available, and we can select any browser from the list like Chrome, Edge, firefox, Internet Explorer, opera, safari, etc.

Following are the sample code for opening the Google Chrome browser:

Step3

In the next step, we will be maximizing our browser window size, and the sample code is as below:

Step4

Then, we will navigate to the given URL.

The sample code is as below:

Note: As we know that Python is a very easy language to write code because we don't have to write multiple statements like as we did it java. Or if we want to comment out something, we just simply put a hash[#] in our statements, or we can directly press Ctrl+ Forward slash [/] from our keyboard.

Step5

In this step, we are trying to locate the Google search text box with the help of its Name attribute value.

• Right-click on the Google search text box, and select the Inspect option in the pop-up menu as we can see in the below image:

• The developer tool window will be launched with all the specific codes used in the development of the Google search text box.
• And, copy the value of its Name attribute, that is 'q' as we can see in the below image:

Here the sample code:

Step6

Once we identify the Google search text box, and we will identify the Google Search button.

So for this, follow the below process:

• Right-click on the Google searchbutton, and select the Inspect option from the given pop-up menu as we can see in the below image:

• The developer tool window will be launched with having all the specific codes used in the development of the Google search button.
• Then, copy the value of its name attribute that is 'btnK' as we can see in the below image:

And, the sample code is as following:

Step7

In the last step, we are closing the browser.

And, the sample code for closing the browser is as follows:

Our final test script will look like this, after completing all the above steps:

Note:
Import time: Time is a Python module, which is used to handle the time-related tasks such as time.sleep().

from Selenium.webdriver.common.keys import Keys:

Here, we are adding Keys libraries from Selenium, like in the above code, we are using the Enter key instead of click() method to perform a particular scenario.

Run and validate the test scripts

Once we are done with writing the Selenium test script, we will run our test scripts.

Here we will run our test scripts in two ways:

• Run in Python IDE
• Run in Command Prompt

Run in Python IDE

So, for this first, we will see how to run the Selenium test script in Python IDE.

• Right-click on the code, and select Run 'Sample1' from the popup menu as we can see in the below screenshot:

• When we run this script it will give an exception because we don't have the Chrome driver executable file as we can in the below image:

To overcome this exception, we will download the chrome driver executable from below link: https://chromedriver.storage.googleapis.com/index.html?path=79.0.3945.36/

• Once we click on the above link, we will click on the zip file based upon our operating system platform. Like we have Windows platform that's why we clicked on thezip to download the Executable file as we can see in the below screenshot:

• After downloading the exe file, we can paste this file to the Python folder and unzip it.
• Then, we will create one more folder called libraries as Browsers in the Python IDE.
• Right-click on the Project(SeleniumTest) → New → Directory as we can see in the below screenshot:

• And, we will add all the driver's executable files in the Browsers folder manually.
• For this, we will copy the chrome driver exe file from the Python folder, and paste in the Browser folder as we can see in the below image:

• Now go to PyCharm IDE, and copy the Absolute path of chromdriver.exe file as we can see in the below screenshot:

• Replace the statement 'driver = webdriver.Chrome()' with a statement given below:

Note: Here, we will use 'r' to overcome the Unicode error.

As we can see in the below screenshot, if we do not put r in the code, it will generate the Syntax Error.

• After that, we will run the sample1 once again, and it will execute the code successfully as we can see in the below image:

The above test script will launch the Google Chrome browser and automate all the test scenarios.

Run in Command Prompt

To run the above test script in the Command prompt, follow the below process:

• Copy the location of the Sample1.py file as we can see in the below image:

• And paste in the command Prompt, first go to the particular folder then enter the below command:
  Python Sample1.py
• Then, press the Enter key as we can see in the below screenshot that the sample test case stared.
• And after automating all the scenarios, it will show the message as a sample test case successfully completed.

Configure PyDev in Eclipse

This is another way to execute the Selenium test script using Python.

In this section, we will install PyDev in Eclipse, then implement the Selenium test scripts on it.
