Description: Data Validation Testing is a set of procedures designed to ensure that the data entered into a system is accurate and valid. These tests are fundamental in software development as they guarantee the integrity and quality of the information being handled. Data validation involves checking that the data meets certain predefined criteria, such as specific formats, acceptable value ranges, and logical consistency. For example, when validating data in an application, one might check that an email address field contains a valid format and that a date field does not contain future dates. Validation tests not only help prevent errors in data entry but also enhance user experience by providing immediate feedback on the information entered. Furthermore, they are essential for compliance with regulations and quality standards in various sectors, such as healthcare, banking, and public administration, where data accuracy is critical. In summary, Data Validation Testing is an essential practice in software development that ensures the information handled by a system is reliable and useful.
