Selenium Fundamentals Questions

Focuses on Selenium as a web browser automation and testing suite and the roles of its principal components. Key areas include Selenium WebDriver which provides language bindings and browser automation APIs, Selenium IDE which offers record and playback for learning and quick prototypes, and Selenium Grid which enables parallel and distributed test execution. Candidates should understand how Selenium interacts with browsers, cross browser considerations and language bindings, strengths such as open source broad browser support, and limitations including challenges with non web applications and highly dynamic JavaScript heavy user interfaces. Additional assessment areas include test architecture, selector strategies, waiting and synchronization techniques, integration with test frameworks and continuous integration pipelines, and approaches to increase test reliability and parallelization.
