Performance testing is a non-functional software testing technique that measures an application’s speed, stability, scalability, and responsiveness under various workloads, ensuring it meets user expectations and business SLAs (OpenText).

It sits within the Quality Assurance (QA) and DevOps toolchain, integrating with continuous delivery pipelines to catch performance regressions early (Parasoft).

1. What It Is

Performance testing evaluates an application’s non-functional attributes—its response times, throughput, resource usage, and stability—under anticipated and peak loads (OpenText). The goal is to identify and eliminate bottlenecks, ensuring the software scales and performs reliably in production (Informa TechTarget).

2. Where It Fits in the Ecosystem

Performance testing is a critical part of QA and DevOps. It integrates with CI/CD pipelines (e.g., Jenkins, Azure DevOps), running automatically on every build to detect regressions early (Parasoft). It sits alongside functional testing, security testing, and automation, feeding metrics into dashboards for monitoring and decision-making (Full Scale).
