The blog post discusses the use of Selenium C# methods, driver.FindElement, and driver.FindElements, which are essential for identifying web elements in automated UI testing. Accurate element location is crucial to avoid false negatives, and various locator strategies such as ID, ClassName, Name, Tag Name, Link Text, CSS Selector, and XPath are detailed for stable test results. The post also introduces relative locators in Selenium 4, which allow element identification in relation to other elements. Two test scenarios are provided: one for finding a single element using driver.FindElement, and another for locating multiple elements using driver.FindElements, both executed on the LambdaTest platform to highlight its capabilities for cross-browser testing and parallel execution. The post further guides on setting up a Selenium C# project in Visual Studio, showcasing the usage of NUnit for testing, and emphasizes the significance of choosing efficient locator strategies to prevent incorrect interactions during tests.
