Software testers can easily build, enhance, and maintain scripts using both the Selenium IDE and webdrivers.
Selenium Webdriver is the most preferred tool for automated testing of web applications. It has evolved from Selenium RC to now Selenium 3.0 to keep up with the market trend.
With the help of Selenium, we can simulate actions on websites like a real user does. It provides a rich set of APIs that we can use to capture a full business workflow for testing the functionality of any web application. Thus, it helps in reducing a lot of manual testing efforts and has now become a W3C standard. It can even work as a cross-browser automation tool for web application testing.
And if you skilled in Selenium then you can get jobs easily and built your career for long term very easily.
To understand Selenium objectives better, test automation is considered obviously parallel as selenium is a test automation tool. So, in an era of highly interactive and responsive software processes where many organizations are using some form of Agile methodology, test automation is frequently becoming a requirement for software projects and applications.
Test automation means using a software tool to run repeatable tests against the application to be tested. For regression testing this provides that responsiveness.
Frequent regression testing
Rapid feedback to developers
Virtually unlimited iterations of test case execution
Support for Agile and extreme development methodologies
Disciplined documentation of test cases
Customized defect reporting
Finding defects missed by manual testing
The consumer is putting increasing demands on organisations to deliver the applications across many devices, browsers and platforms. So with increasing pressure being put on test tool budgets, IT professionals are now looking to the open source market for the test automation tools.
Selenium allows both the developers and testers to automate tests against applications and execute them against multiple browsers.
Selenium is possibly the most widely-used open source solution. Selenium is a free (open source) automated testing suite for web applications across different browsers and platform.
Selenium is not just a single tool but a suite of software’s, each catering to different testing needs of an organization. Each of these are highly flexible, allowing many options to locate UI elements and compare expected test results against actual application behavior. One of Selenium’s key features is the support for executing one’s tests on multiple browser platforms.
Selenium is probably the best option for automated testing of Websites today and is becoming increasingly popular among automation testers as well as organizations for automating the testing of Web-based applications for both the GUI as well as the functionality.
It supports C#, PHP, Java, Perl, Python. It supports different OS like Windows, linux and Mac OS It has got powerful methods to locate elements (Xpath, DOM , CSS).
Should have basic knowledge of Manual Testing.
