Why are test cases critical in ensuring application reliability in Pega?

Test cases play a vital role in ensuring application reliability in Pega because they help identify issues before software deployment. By systematically outlining the expected behavior of an application, test cases provide a structured way to validate various components and scenarios. This preemptive testing allows developers and testers to spot bugs, inconsistencies, or performance issues early in the development lifecycle, reducing the risk of defects appearing in the live environment.

Addressing issues prior to deployment is crucial, as it not only saves time and resources but also enhances user satisfaction and trust in the application. The thoroughness of testing through well-defined test cases can lead to a more stable and robust application, ultimately supporting the overall goal of delivering high-quality software. As a result, test cases contribute significantly to the reliability and performance of applications developed in Pega.
