To take complete advantage of Selenium WebDriver’s capabilities for automated testing, understanding advanced techniques is crucial. The Selenium IDE, Selenium WebDriver, and Selenium Grid are the tools used for Selenium testing.

• Selenium WebDriver: A browser-based driver that facilitates access to and launching of various browsers in various settings.
• Selenium IDE: An integrated development environment that facilitates the capturing, editing, troubleshooting, and replay of functional tests.
• Selenium Grid: Distributed test execution, often known as parallel testing, allows for testing across multiple computers using various operating systems and browsers.

WebDriver – A Brief Overview

A programmatic interface for working with live web browsers is called WebDriver. It makes it possible for test automation to launch a browser, transmit clicks, press keys, input text, and then cleanly close the browser. 

The W3C recommends the WebDriver interface. The most widely used open-source and free WebDriver implementation is Selenium WebDriver.

Components of Selenium WebDriver

1. Language Bindings

Browser interaction programming language bindings are offered by packages like Selenium WebDriver. Major scripting languages, including C#, Java, JavaScript, Ruby, and Python, are supported by Selenium.

2. Robotics Code

Language bindings are used by programmers to automate browser interactions. Finding components, selecting them, and scraping text are frequent interactions. Typically, a test automation framework is used to write this.

3. JSON Wire Protocol

Every interaction is JSON-encoded via language bindings, which then send REST API calls to the browser’s driver. The JSON wire protocol works with any platform and any language.

4. Browser Driver

On the test machine, the driver is a standalone executable. Between the caller of the interaction and the browser itself, it serves as a proxy. It receives JSON interaction requests and uses HTTP to communicate them to the browser.

5. Browser

The browser displays the test web pages. The driver essentially controls it. WebDriver is supported by all popular browsers. Additionally, every browser requires a specific kind of driver that must be installed on the same machine as the browser and reachable from the system path. Google Chrome, for instance, needs ChromeDriver.

Frequently Asked Questions 

1. What Are the Advantages of Utilizing Selenium?

A few advantages of the Selenium Software Testing Tool include test automation, widespread use in the software industry, and increased test dependability.

2. How Might the Readability of Tests Be Enhanced With Selenium?

You can utilize Selenium’s numerous built-in tools and routines to validate your data insights. However, there are situations when you must have the queries available while validating application-specific data.

3. What Is the Best Way To Use the Selenium Testing Tool as a Development Tool?

Applications that haven’t been fully completed yet can be tested using Selenium as a development tool. To accomplish this, you can make unique assertions that validate data particular to your application.

4. What Distinguishes a Custom Assertion From One That Is Included With Selenium?

A Java class called a custom assertion enables you to provide metadata in your code. Despite the fact that they resemble JavaDocs, they are used to add metadata as opposed to documenting your code. A tool that can be used to validate data is an assertion that comes with Selenium software testing.

No matter what, always terminate the WebDriver instance after a test is finished. When test automation is finished, driver processes on the test machine won’t always terminate. A driver instance that has not been explicitly terminated may continue to function as a zombie process, consuming and even locking system resources.
