Selenium - Testing Web Applications

Automated software testing is an integral part of the quality assurance of software projects. While many developers use unit and integration tests to ensure the correct functionality of individual components (integrated), an automated system test is often lacking from the user’s point of view. This is precisely where Selenium comes into play. Selenium allows you to fully test web applications from the user interface to the database and thus verify the functional correctness of the overall system. For the purpose of these tests, user interactions can either be recorded using Selenium IDE and then played back as often as desired (parametrized) or test cases can be created in a programmatic way (using Selenium RC or the WebDriver API). Using Selenium Grid, it is also possible to perform these tests in a parallel and distributed way, for example, to test the application in different browsers and on different operating systems.

In this training, you will learn how to use Selenium and Selenium Grid for automating parallel and distributed system tests. In order to make the individual test cases as easy as possible to modify and expand according to common paradigms of object orientation, another focus is on a sustainable architecture of the Selenium tests, as well as general best practices.
