Have you heard of Selenium? Do you know what it is? Selenium can be a helpful tool when building your web automation, but there are many aspects to consider before deciding if using Selenium is right for you.
In this article, we’ll cover everything from what Selenium actually is to how it works and we will tell you the reasons for which many professionals are adopting selenium in their automated tests. Selenium is one of the best, free, and open-source testing frameworks for browser and web applications. It is a portable tool with which you can write automated tests. There are many advantages of using selenium over any other testing tools like JUnit or TestNG. According to my view, it is the best approach towards unit testing of your Web Application.
What is Selenium?
Selenium is a very powerful open-source framework, developed primarily in java for cross-platform testing automation. It’s an automated tool that helps in regression testing of web applications. It can also be utilized to maintain the application by running the test cases.
Selenium is a key web scripting engine that allows web developers to easily create automation scripts to test web pages in combination with the live page viewer that is part of their browser. Selenium is widely used by numerous sites such as online exam software provider Aptos, Paypal, Amazon, and many others. This opens up the possibility for testing changes that could affect the usability of these applications during the development process.
Advantages of Selenium
From the beginning, I am stating that there is no alternative to selenium. It has many advantages which make your work easier and at the same time you will achieve good results.
- Easy to use
- Selenium is widely used in the field of web browsers to test web applications. It runs automation tests that check for common errors in website functionality, presenting a report with detailed information about the results of each test
- It’s used in an array of industries including automotive, financial services, education, healthcare, and others.
- It supports numerous languages including PHP, Ruby on Rails, and Vue.
- Using selenium over any other testing tools like JUnit or TestNG.
- There is no secured support available for Selenium IDE, as we need to leverage the accessible customer communities for testing.
Selenium Suite Of Tools
- Selenium RC Tool: The Selenium RC (Robustness, Consistency, Recovery) tool is a web development tool that helps developers test their websites with real users instead of running them through a database. Selenium is used in many industries, including software development and testing, but its main purpose is to check if a website or web app works as it is supposed to. If something is broken or not working as expected, this is when the Selenium RC tool comes in handy. This piece of software looks for errors in your code and if any are found, it reports them back to you. It also allows you to upload files and run tests directly from your browser without having to install any other software on your computer.
- Selenium Grid Tool: Selenium Grid is a must-have tool for any web developer who’s serious about mobile development. If you’re looking to build robust and high-quality mobile applications in a soundbite-friendly manner, then Selenium Grid is a must-have addition to your toolkit. Selenium is used by over 50,000 developers and 55 percent of them say their projects use Selenium to generate code.
- Selenium WebDriver Tool: The Selenium WebDriver is a web driver that allows you to test web pages without installing any browser extension or running them in a separate browser process. This saves time and simplifies things for developers when writing automated tests for your site. What does this mean for us developers? It means faster and more reliable downloads for our applications. This will be useful for ensuring your site works as expected in all environments, including users who might not have an active developer subscription but still want to test changes before pushing them into the live production database.
Automated Testing Beats Manual Testing
Before we proceed more, let me clarify that there are two kinds of software testing: manual testing and automated testing. Selenium was designed as a test automation tool to overcome the shortcomings/limitations of manual testing. So, in the next part of this selenium blog, we’ll look at the problems with manual testing.
One challenge with testing is that it’s manual. There’s no automated way to conduct a test and make observations as quickly and easily as you can with a scorekeeper. With manual testing methods, you’re forced to make observations by comparing notes with other testers as well as analyzing data collected from the results of your tests. It’s not for everyone. Manual testing is slow, often uncertain, and deals with unknowns. It’s also more valuable: The time spent making sure a test suite runs smoothly is time lost that could be spent shipping software. Manual testing involves running actual applications under specific scenarios and then reporting on the results.
Automation testing improves software quality by reducing time to market, and it provides useful feedback so that human testers can catch bugs before they become critical. Automation testing can replace whole teams of testers and their time-wasting. You can test and refine ideas as an automated process gradually takes over, giving you valuable feedback before you make any changes.
