What is selenium| Definitions, Pros, Cons, Applications

Selenium has been used for many years on almost every Operating System available, mainly because of its popularity with web application developers (webmasters) who use it to test websites and web applications.

What is Selenium?

Selenium Automation lets you write scripts that can perform actions on your website or web application without having any previous knowledge about it. It is a portable and small programming language used to automate various tests. Selenium automates the web browsers such as Chrome, IE, and Firefox. These scripts can be executed by clicking an HTML button or using other input elements like text boxes and buttons etc., which makes it easy for developers/ testers to test their websites without having any knowledge about their architecture or structure.

Selenium is based on Java web browser programming language. It can be used to automate any kind of web application, including websites and mobile apps. Java is a popular programming language that has been widely used in many different areas of computer science; it's also the most widely used general-purpose programming language in the world today, with over one billion users. When you use Selenium with your computer or smartphone, you are interacting with the underlying operating system (OS) through APIs like JavaScript or C+. Since we have explained some concepts regarding the trending keywords “what is selenium”, let's further learn its features and testing applications.

Features of Selenium:

Selenium supports the open-source project called Selenium WebDriver by Google. The main aim of this technology is to write automated tests that would help you in creating faster and better software products. It can be used as an alternative method for web automation testing because it has many advantages over other methods like JMeter or Watir etc., which makes it quite popular among developers all around the world. Selenium Testing is important for Agile Development techniques, it helps to maintain product quality and performance, especially where there are multiple environments like different browsers then different operating systems involved.

Some elements make Selenium more complex than other tools that may be familiar to you in your current role as a developer or tester:

• The WebDriver API allows for Java programming language interaction with the browser and has been designed specifically for ease of use in testing websites and web applications; this is one of the reasons why Selenium has become so popular among web developers.
• When used as part of a larger system like Jenkins or GAE, Selenium interacts with scheduled jobs instead of being run from the command line which can make using it difficult if you are unfamiliar with programming via text editors or IDEs such as Sublime Text or IntelliJ or JAVA IDE's like JDeveloper which are integrated into most modern IDEs these days; often these IDE's have built-in support for writing tests such as EclEmma plug-ins that allow you to write your tests in HTML5 tags on a page and view them inline without changing them (this makes testing easier during development time).

What types of automated testing can be performed with Selenium?

Regression Testing

Regression tests are used to test the functionality of a code base after a change. They’re run after every change to the code base, and they’re also run before each new release and can be done with selenium. Regression tests can be automated with Selenium, but keep in mind that there are some important things you should know about them before you start automating them. WeTest also has far better mobile app test automation services with real-world iOS and Android devices and integrates with all the famous CI and CD tools in the current practice.

Unit Testing

Unit tests are small, isolated pieces of code that test a single function. They're often written after the feature has been implemented but before it's integrated into a larger application. Unit tests are therefore the first line of defense against bugs—they allow you to know when your code works and what doesn't work before integrating it into your full project.

Performance testing is a type of stress test

It can be used to test system performance under pressure, or how well a system performs under stress. Also known as load testing, it can be done with selenium, and it's one of the most important aspects of software development because it helps you identify potential problems before they become serious issues that affect your users' experience with your product or service.

Automated systems testing with Selenium

Selenium is a popular open-source framework for automating web applications. It can be used for automating web applications, but it can also be used to test other types of software as well. Although there is a lot going on for Selenium, we recommend opting for WeTest which offers similar testing and analyzing tools with much better team collaboration methods, support for more real-world smart devices, and an experienced team that has worked with big players in the industry like Riot Games, SuperCell and more.

Wrapping Up:

To wrap up the topic "what is selenium", we can conclude that Selenium is an open-source toolkit for automating web browsers across multiple platforms, allowing you to perform browser-based exploratory testing on any device or operating system without installing any software or modifying any existing programs.
