How do test cases aid in application development in Pega?

Test cases play a critical role in application development within Pega by validating application rules under various conditions. This validation ensures that the rules behave as expected and adhere to defined business requirements. By systematically testing different scenarios, including edge cases and typical user experiences, developers can identify any discrepancies or faults in the application's logic and functionality.

This process helps ensure that the application not only meets its intended specifications but also functions reliably across different environments and use cases. Comprehensive test cases contribute to maintaining the quality and stability of the application, thus minimizing the risk of issues arising when the application is in production. Additionally, thorough testing helps with regression checks when new features are added or existing functionality is modified, ensuring that previous functionality remains intact and performs as expected. This aspect is essential in managing the continuous delivery of updates within Pega applications.
