How Do You Capture Screenshots on Test Failures in Selenium Java?

Capturing screenshots on test failures in Selenium Java is essential for debugging and understanding the exact state of the application when errors occur. Typically, testers use the TakesScreenshot interface from WebDriver. You can implement this inside a TestNG @AfterMethod hook to automatically trigger screenshot capture whenever a test case fails. Save the file using a unique timestamp or test name for better traceability. During execution, storing screenshots in a structured folder format helps in easy reporting and defect analysis. Many QA teams integrate this with Jenkins and Extent Reports to automate result sharing. In the middle of Selenium online training, learners practice this hands-on for real project workflows.
