To assess the impact of high user volumes on overall system stability, Error Rate serves as a critical metric in scalability testing. This metric quantifies the percentage of failed transactions or errors encountered during test execution. If error rates start rising exponentially with increased concurrent users, it signifies potential weaknesses in code logic or hardware infrastructure. Identifying these vulnerabilities early allows developers to address them promptly and prevent service disruptions or dissatisfied customers.

In conclusion, by considering key metrics such as Response Time, Throughput, and Error Rate during scalability testing, organizations can effectively evaluate and enhance their software testing performance. These metrics provide valuable insights into system behavior under varying workloads and enable proactive optimization measures before real-world issues arise.
