Why learn Selenium?

Benefits of using Selenium include:^{Footnote 2}

• Automation: The Selenium automation framework allows users to perform repetitive tasks such as regression testing, functional testing, and load testing with minimal effort. This saves time and effort compared to labor-intensive manual testing.

• Cross-browser testing: Developers can use Selenium to test web applications across different browsers, such as Chrome, Firefox, Safari, and Internet Explorer. Web-based applications can behave differently on different platforms, so cross-platform testing is necessary to ensure that web applications work as predicted across all browsers. 

• Language support: Selenium is compatible with several programming languages, including Java, Python, C#, Ruby, and JavaScript. Therefore, you can use your preferred programming language when creating Selenium scripts.

• Integrations: Selenium is compatible with a wide range of third-party tools like Jenkins, TestNG, and Maven. You can leverage these integrations to automate the entire testing process, from running tests to generating reports.

• Community support: Selenium has a large, active community of developers who contribute to its development and help to improve its functionality. Online resources such as documentation and tutorials are available to help you learn Selenium effectively. 

Selenium tutorial curriculum

If you are interested in how to learn Selenium online, you can start out in an introductory Selenium tutorial that can cover how to set up the tool and begin to use the different components of the platform. Once you have familiarized yourself with the tool, you can dive deeper with lessons that cover topics such as:

• Selenium WebDriver commands and methods

• Locators in Selenium

• Testing frameworks (e.g., TestNG, JUnit)

Selenium is a popular tool among professionals across the software development and software testing industries. Job roles that can use Selenium include:

• Web developers: Web developers create and manage websites and web applications and are responsible for the site’s technical performance.^{Footnote 3} They may use Selenium Grid to carry out automated testing for web applications to identify issues before the application is launched, saving time and money. 

• Software quality assurance analyst: Software quality assurance analysts are essential for ensuring the quality of new and existing software. They are responsible for identifying risks and developing test plans.^{Footnote 4} These professionals may use Selenium to conduct tests to identify problems with applications or programs and report defects.

• Back-end developer: Back-end developers oversee the technical construction of websites, which includes tasks such as creating the framework, ensuring functionality, and establishing procedures for adding new pages.^{Footnote 5} Back-end web developers may use Selenium Grid to test and automate interactions on the server side of web applications.

• Software developer: A software developer creates software applications and systems and can use Selenium to test and automate interactions on web applications' front- and back-ends.^{Footnote 6}

If you're interested in pursuing a career in web development or related fields, consider taking a coding boot camp to help you gain career-critical skills on an accelerated timeline.

How to use Selenium in your career

Many professionals, like software developers, quality assurance (QA) engineers, and software testers, use Selenium.

Software developers use Selenium to test their web applications and ensure they work as expected. With multiple machines, they can use Selenium Grid, in particular, to automate parallel test execution on a wide variety of browsers and operating systems.^{Footnote 7} They can use Selenium to automate functional and regression tests, saving them time and increasing their tests' accuracy.

QA engineers and software testers might use Selenium to create and run automated tests for web applications. They may also rely on Selenium to test an application's functionality, as well as its performance and usability. Selenium is known to test the compatibility of web applications on different platforms and browsers.

To start using Selenium, as a prerequisite, it’s good to have a basic understanding of software testing and programming concepts. Some comfort with programming languages like Java, Python, or C# is also recommended. A basic understanding of how web browsers work and how to use web development tools like HTML editors, CSS preprocessors, and web servers can provide further context as you study Selenium. 

Professionals in the field of Selenium automation and testing leverage strong analytical and problem-solving skills as well as attention to detail. This allows them to quickly identify and troubleshoot issues that arise during testing. Additionally, working in a team environment means they have to learn how to communicate effectively with developers and other stakeholders.
