Options for Manual Test Case Development & Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.
