The blog post "How To Find Hidden Elements In Selenium WebDriver With Java" addresses the challenges of automating web applications when elements are present in the DOM but not visible on the page, leading to exceptions like ElementNotInteractableException or ElementNotVisibleException. It explains that hidden elements can be created using HTML attributes or CSS properties and provides strategies for identifying and manipulating these elements using Selenium WebDriver with Java, particularly through the use of JavaScript Executor to alter element visibility at runtime. The article includes practical examples, code demonstrations, and emphasizes the importance of ensuring hidden elements are accessible for testing without causing unexpected application behavior, ultimately guiding readers on handling hidden elements effectively in automated tests.
