Another popular open-source tool to automate browsers is Selenium. It works with a variety of programming languages, including Java, Python, Ruby and C, and therefore offers a cross-purpose alternative of test automation. Selenium is a very famous tool to test web-based apps, web data mining, and automation of tedious tasks
Key Features of Selenium
Selenium is one of the most essential test automation tools, which has some main peculiarities to be considered. It is multi-browser capable, i.e., tests can be executed on different browsers. Also, Selenium is open to a variety of programming languages and has a sandbox architecture that can be extended. When the community is large, it will have ample resources. To further know about it, one can visit Selenium Online Training.
- Support the different browsers: Selenium can work with many browsers, i.e. Chrome, Firefox, Safari and Edge.
- Multi-Language Support: Selenium supports a variety of programming languages, and this helps in combining it with other test frameworks.
- Extensible and Flexible: Selenium is an extensible and flexible framework in such a way that users are allowed to extend and tailor to functionality.
- Vigilant Community: Selenium has a large and active community, and hence it has no dearth of resources to learn it as well as solve problems.
Selenium Components
Three main elements make selenium a good candidate to use in the effective automation of tests. Programmatically, Selenium WebDriver provides an interface to the browser. Selenium IDE is a record-and-play tool that is used in generating test scripts. With Selenium Grid, it is possible to conduct distributed testing on lots of machines and browsers.
- Selenium WebDriver — Selenium WebDriver is the most significant component of Selenium. It provides a programmatic means of speaking to web browsers.
- Selenium IDE: Selenium IDE is a test script writer, and it uses replay and record. It allows the user to record the interaction with the web-based application and generates the test scripts.
- Selenium Grid: The Selenium grid is a distributed test infrastructure. It allows the user to do parallel testing between machines and browsers.
Benefits of Using Selenium
Selenium has a lot of advantages when it comes to automating tests and enhancing the efficiency of tests and coverage. Selenium automates routine procedures and thus minimises human error, and works with most browsers and operating systems. Being an open-source application, Selenium is also a cost-efficient tool in organisations.
- Enhanced testing productivity: In Selenium, testing productivity is accomplished in light of automating programmed tests.
- Test Coverage: Selenium enables the user to test web applications over a variety of browsers and platforms, and hence provides greater test coverage and compatible functionality.
- Open-Source: Selenium is an open-source utility tool and hence involves zero costs as a means of automating the tests.
Use Cases for Selenium
Selenium is thus a productive tool when it comes to multiple applications. It finds considerable usage in testing web applications, and in particular, it guarantees their functionality and cross-browser support. In conjunction, Selenium is applied in the process of data scraping and automation of monotonous work, organizing processes and raising efficiency.
- Web Application Testing: Selenium is very popular in testing a web application, which makes sure whether the application is functioning properly and whether it can be used with other browsers.
- Data Scraping: Selenium is also suitable for scraping the data exhibited in web applications, particularly with complex JavaScript rendering.
- Automation: Repetitive tasks, e.g. filling out forms or clicking buttons, can be done using Selenium.
Best Practices for Using Selenium
The best thing to do to utilize the capabilities of Selenium is to follow best practices that entail efficient and reliable test automation. These rules will assist you in writing more maintainable and efficient test scripts. Since test automation is a robust practice, there should be proper planning and execution of the same. The profession of a Selenium professional is in demand in cities such as Noida and Delhi to a very large extent. So, the Selenium Training in Noida can assist you in making a career in this field. Here are the best practices that can make you successful.
- Adopt a Page Object Model: A page object model is a design pattern that makes it easier to provide structure to the elements that make up a web page and the actions to be used on the web page, making test scripts easier to maintain and more efficient.
- Explicit Waits: By using explicit waits, users can ensure waiting until certain conditions are met, after which they will be able to interact with a web page, and this eliminates cases where the test may fail.
- Test Framework: A test framework allows the structure of tests and the execution of tests; managing and maintaining test scripts is also easy.
Conclusion
An automation tool that automates web browsers, Selenium provides testing automation and acts as a data scraper with its numerous advantages. Major IT hubs like Noida and Delhi offer high-paying job roles for Selenium professionals. Therefore, enrolling in the Selenium Training in Delhi can help you start a career in this domain. A grasp of what it does, the catches, components and best actual practice will enable users to drive a very productive Selenium that helps to maximise test efficiency and coverage as well as minimise the cost of tests.
