Explain about the Selenium Webdriver?

When it comes to Web UI automation, Selenium WebDriver is among the most common tools. With a large variety of programming languages, such as Python, Java, C#, and more. Then you can use the Selenium framework. As per the Stack Overflow Developer Survey, with 66.7 percent, Python is the best language. It is also the programming language that is most sought after. So, if you intend to run Selenium and Python test automation, you're in the right spot!

Let us cover a variety of subjects in this comprehensive Selenium Python. This is such as the fundamentals of Selenium WebDriver. You can learn Selenium WebDriver with Python, Selenium WebDriver vs. Selenium RC.

What's the WebDriver for Selenium?

A web page is up of various web components. This is such as text boxes, checkboxes, buttons, etc. Checking for web automation requires automating the tasks. You can perform on certain elements of the web. Selenium WebDriver is a common platform for web-based automation testing. Thus, you can use that to automate Web UI testing tasks.

Selenium WebDriver does not interfere with a page's web components. A Selenium WebDriver unique to the browser serves as the connection. This is between the test script and the web browser. The main component which communicates with the web browser is the Selenium WebDriver.

Selenium WebDriver supports Python, Java, C#, Ruby, and more. These are most of the common programming languages used by developers and testers. Popular operating systems such as Windows, Mac OS, Linux, and Solaris support.

By default, the Selenium WebDriver web browser is Mozilla Firefox.

Selenium WebDriver Architecture

Before looking into Selenium WebDriver with Python, understanding the communication. This is between different blocks of Selenium is important. For interacting between programming languages and web browsers, Selenium WebDriver APIs use.

The following blocks from the Selenium WebDriver architecture.

● Client Libraries for Selenium

● Protocol on JSON Wire

● Drivers for Browsers

● The Browsers

Let's take a thorough look at each of these elements.

Client Libraries for Selenium

As stated earlier, developers can use Selenium with common programming languages. This is for performing automation testing. Moreover, this multi-language support is possible in Selenium. This is through Selenium Client Libraries or Selenium Language Bindings.

Using Selenium WebDriver with Python is the subject of this Selenium Python. Thus, for Python, we will need language bindings. You can download the programming language drivers. You can include Python, from the official Selenium location for Client Libraries.

Protocol on JSON Wire

JSON stands for Object Notation in JavaScript. To pass data between the server and the client on the network, the JSON Wire Protocol used. It is a REST (Representational State Transfer) API that makes it easier for the HTTP Server. This is to transfer information.

Each web browser has its browser driver, Chrome, Firefox, Internet Explorer, etc.

Drivers for Browsers

The primary responsibility for interacting with the corresponding web browser is browser drivers. Each browser has its browser driver. Then the same must install on the computer that carries out the automation tests.
