What is Selenium?
Selenium is an open-sourced automated testing tool that is used to test web applications across various browsers. It was developed by Jason Huggins in 2004 and was written in Java. It is a powerful automation tool that can be used to validate and verify a web application.
Why is Selenium so popular?
- Selenium is easy to use as it provides a user-friendly interface that helps create and execute tests easily and effectively.
- It is a publicly available automation framework that is freely accessible to anyone. It is therefore an open-sourced framework.
- It saves a lot of time and effort as multiple tests can be run in parallel.
- It is platform independent and can work with various operating systems like Windows, Mac, Linux/Unix.
- It works with various web browsers like Safari, Chrome, Microsoft Edge and Firefox.
- Tests can be coded in various programming languages including Java, Python, Ruby,Perl and PHP and Selenium converts it into compatible source in no time.
- Selenium can be integrated with tools like JUnit and TestNG for test management.
- It can also use with with testing frameworks like PyTest and Python Behave and also with CI/CD framework like Jenkins.
- Selenium requires less hardware compared to other testing tools.
Although Selenium has a number of advantages, it also has a few disadvantages that need to be taken into consideration.
These include:
- It has limited support for desktop applications and is mainly designed for online application testing.
- The program writing time is high and requires good programming skills.
- Selenium does not have built in reporting capabilities and testers must therefore depend on third-party reporting tools.
- You cannot automate CAPTCHA and SMS based OTP web applications.
- It has a small community so it lacks proper online support so you need to put a lot of efforts to find solution to your problem.
- Seleniums automation depends on the browser's automation capabilities which can sometimes lead to inconsistencies across different browsers.
In conclusion, although there are a few disadvantages to using Selenium for automation testing, it is widely used because of it flexibility and easy of use.
