Test Data
Test Data refers to the information that quality assurance professionals use to check if software works correctly. Think of it like a set of scenarios or examples that help verify everything functions as expected. Just as you might test drive a car with different road conditions, test data helps testers try out software under various situations. This includes both realistic information (like common customer details) and edge cases (unusual situations that might cause problems). Having good test data is crucial for finding problems before real users do.
