Comprehensive Software Test Strategies for Subscription-Based Applications and Payment Systems

Abstract

Subscription-based digital platforms and payment systems operate at the intersection of reliability, performance, and financial compliance. Failures in these systems can result in financial loss, regulatory repercussions, and reputational damage. Ensuring resilience—the ability to maintain service availability and data consistency under stress or failure conditions—is therefore paramount. This paper presents a comprehensive set of test strategies to validate and improve the resilience of subscription apps and payment platforms. The proposed methodologies span chaos testing, load testing, disaster recovery simulation, and fault injection, all integrated within automation and CI/CD to enable continuous resilience assurance.
