Sep 21, 2019 Selenium Webdriver using Python: Tutorial with Example Selenium supports Python and thus can be utilized with Selenium for testing. Python is easy compared to other programming languages, having far less verbose. The Python APIs empower you to connect with the browser through Selenium. This is not an official documentation. If you would like to contribute to this documentation, you can fork this project in Github and send pull requests.You can also send your feedback to my email: baiju.m.mail AT gmail DOT com. Selenium: Selenium Python bindings provide a convenient API to access Selenium Web Driver like Firefox, Chrome, etc. What is webdriver? Selenium WebDriver is an automation testing tool. When I say automation, it means it automates test scripts written in Selenium.
WebDriver is a tool for automating testing web applications. It is popularly known as Selenium 2.0. WebDriver uses a different underlying framework, while Selenium RC uses JavaScript Selenium-Core embedded within the browser which has got some limitations. WebDriver interacts directly with the browser without any intermediary, unlike Selenium RC that depends on a server. It is used in the following context −
Architecture
WebDriver is best explained with a simple architecture diagram as shown below.

Scripting using WebDriver
Atif aslam songs download free mp3 sad songs. Let us understand how to work with WebDriver. For demonstration, we would use https://www.calculator.net/. We will perform a 'Percent Calculator' which is located under 'Math Calculator'. We have already downloaded the required WebDriver JAR's. Refer the chapter 'Environmental Setup' for details.
Step 1 − Launch 'Eclipse' from the Extracted Eclipse folder.
Step 2 − Select the Workspace by clicking the 'Browse' button.
Step 3 − Now create a 'New Project' from 'File' menu.
Step 4 − Enter the Project Name and Click 'Next'.
Step 5 − Go to Libraries Tab and select all the JAR's that we have downloaded. Add reference to all the JAR's of Selenium WebDriver Library folder and also selenium-java-2.42.2.jar and selenium-java-2.42.2-srcs.jar.
Step 6 − The Package is created as shown below.
Step 7 − Now right-click on the package and select 'New' >> 'Class' to create a 'class'.
Step 8 − Now name the class and make it the main function.
Step 9 − The class outline is shown as below.
Step 10 − Now it is time to code. The following script is easier to understand, as it has comments embedded in it to explain the steps clearly. Please take a look at the chapter 'Locators' to understand how to capture object properties.
Step 11 − The output of the above script would be printed in Console.

Cross-browser testing is deemed to be an indispensable task for the modern-day release cycle. However, manual cross-browser testing could turn out to be very strenuous and time-consuming. This is a major hindrance that developers and testers face while performing browser compatibility testing for their website or web application across different operating systems, browsers, etc. This is where Selenium, a free and open source software, steps in!

Selenium is a popular automation testing framework for browser compatibility testing and is utilized for performing automated functional testing with less/minimal learning curve with respect to implementation. Selenium and Python: Getting Started — Installation, Configuration, and MoreSelenium supports the most popular programming languages for testers, namely C#, Java, Ruby, Python, Javascript, PHP, etc., but many developers and testers are opting for Python with Selenium since Python is less verbose than other programming languages. Also, Python libraries are very extensive and help you get more work done by writing clean and better automation code. Now that you have understood the advantages of using Selenium with Python for automation testing, we explain the basic steps for installation and configuration. Note: In this blog, we use the Windows Environment, Python version 3.6, and Eclipse as Selenium IDE. Let's get started:
Selenium requires the geckodriver in order to communicate with the Firefox browser. For performing parallel testing in Selenium, WebDriver and various browsers can be downloaded from the following locations:
Option 2 [Line 11] can also be used in case you plan to manually invoke geckodriver.exe, which, in turn, starts a Firefox instance. The usage of Selenium Web Server is optional, and it all depends on the manner in which you want to use the Selenium WebDriver. If you are planning to perform parallel testing in Selenium WebDriver with Python, or any other language through your local machine, where you have web browsers on which you intend to use for browser-compatibility testing, WebDriver API would suffice for your requirements. Selenium WebDriver would directly run the browser. Below are the ideal scenarios where you would require the Selenium Web Server:
Selenium Webdriver ExampleThe Selenium Web Server can be downloaded here. Selenium WebDriver With Python – Usage and ExamplesNow that you have the setup ready, you can now use Selenium WebDriver Python Bindings for the testing of your web application. Below is a simple piece of code that I used for Python automation testing; it will work with the ‘search functionality’ in Google. Example 1You can save the file as search.py and compile using the following command:
Note: In case you are using an IDE like Eclipse, you can compile and execute your code using the PLAY button in the Eclipse IDE. Let’s do a code walkthrough and have a look at some of the critical parts in the above example for Selenium Webdriver for Python automation testing. Import the selenium.webDriver module that provides the Create a Firefox Open the home page. In any case, the The next step is to locate the necessary element on the Web Page. WebDriver offers a number of ways in which Any pre-populated text in the input box is cleared using the Finally, the browser session is closed using the Now that you know how Selenium, Python, and WebDriver can be used; we proceed to the next section where we discuss how Selenium can be used for writing effective test cases. In order to write test cases using Selenium, the unittest module has to be imported. Though there are other options like py.test and nose, we will focus on Example 2The above test code can be executed from the shell using the command Before getting into the actual implementation, important modules are imported. Now, we start with the actual The Once the initialization is done, we proceed with the The The implementation in the The final lines of code are the boilerplate code to run the test suite; The examples that we have showcased above have a Firefox and Chrome browser at the center of the entire testing process. What if your requirement is to test your web app with just the Firefox browser (version 64.0) installed on a Windows 10 machine? In such a process, you would need the required setup with the same version of Firefox installed on it. This approach is not only expensive but it is also non-scalable. ConclusionPerforming parallel testing in Selenium WebDriver with Python for automation testing could save you a lot of time by speeding up your slow automated UI tests. If there are less number of tests, you might not require parallel testing in Selenium WebDriver for Python or any other language, but once the complexity of the project increases (or the number of tests to be executed increase), parallel testing is the ideal mechanism to achieve the best results in the minimum possible time. Nowadays, more teams are focused on making use of Continuous Integration (CI) and Continuous Delivery (CD) in the overall software development and testing process. Getting the best out of ‘parallel testing’ is important for the implementation of Continuous Integration (CI). Happy testing! Like This Article? Read More From DZone
