What is Selenium
Selenium is an open-source, free automated testing toolkit for web applications that works with various platforms and browsers. It resembles HP QuickTest Pro considerably (QTP, currently UFT). Selenium, on the other hand, specializes on automating web-based applications.
Selenium testing is the term used to describe testing carried out with Selenium. Keep in mind that Selenium can only be used to test web applications. Both desktop and mobile application testing are not supported.
What is Selenium Used For?
Selenium is used by the majority of programmers and developers who create website apps and occasionally want to test them. Selenium’s adaptability is one of the main benefits that has contributed to its popularity. Selenium can be used to test code and apps by anyone who develops web programming. Additionally, experts can troubleshoot and carry out visual regression testing in accordance with the demands of the website or code.
Selenium web application testing is typically the responsibility of quality analyst (QA) engineers in businesses. To make modifications to the project and keep up the test infrastructure, they must write scripts that can maximize accuracy and test coverage.
QA engineers are in charge of creating test suites that can find defects so that they can educate stakeholders about the project’s benchmarks. The main objectives of QA engineers are to guarantee effectiveness, test coverage, and productivity growth.
What Types of Testing can be Automated by Selenium
- Compatibility Testing
- Performance Testing
- Integration Testing
- System Testing
- End-to-end Testing
- Regression Testing
Selenuim Components
There are 4 components of Selenium –
- Selenium IDE
- Selenium RC
- Selenium WebDriver
- Selenium Grid
Selenium IDE
Firefox plugins make up the majority of the Selenium IDE (Integrated Development Environment). It is among the Selenium Suite’s simplest frameworks. We can record and replay the scripts thanks to it. Use Selenium RC or Selenium WebDriver to construct more complex and reliable test cases if you want to write scripts using Selenium IDE.
The execution of test cases in Selenium IDE is quite slow, and the test case report creation process is subpar when compared to other components. Both parallel and remote test case execution are not supported.
Selenium RC
Before Selenium 2 and the WebDriver merging, Selenium RC, often known as Selenium 1, served as the primary Selenium project. For automation, it primarily uses JavaScript. Ruby, PHP, Python, Perl, and C#, Java, and Javascript are all supported. It works with practically all current browsers.
Selenium WebDriver
Selenium WebDriver is a framework for automating browsers that receives instructions and transmits them to a browser. It is implemented via a driver that is unique to the browser. It commands the browser directly and communicates with it. Programming languages supported by Selenium WebDriver include Java, C#, PHP, Python, Perl, Ruby, and Javascript.
Selenium Grid
A tool used in conjunction with Selenium RC is Selenium Grid. It is utilized to perform tests concurrently across several devices and browsers. This requires running numerous tests simultaneously against many machines running various operating systems and browsers.
