Load testing vs stress testing vs performance testing. You may want to jump in, pick a load testing tool and start testing, but lets take some time to establish our methodology first. So in most cases, software development methodologies could, with some adjustments, be applicable to performance testing. Have a look at our other software testing services and learn how spritecloud. Before testing begins, start by understanding requirements. In performance engineering, we have our own testing methodology and best practices. Software testing methodology is defined as strategies and testing types used to certify that the application under test meets client expectations. However, to test the upper limits of the system from the perspective of concurrent user load, capacity planning tests should be used. Performance testing is an important part of any aem deployment. Load testing is the simplest form of performance testing.
Load testing, stress testing also called torture testing sometimes, soak testing. Performance, load, and stress testing push every facet of the application to its. Main goal is testing for scalability, availability, and performance from the point of hardware as well as software. Stress testing takes this a step further and is used to gauge how your software will respond at or beyond its peak load. Load testing can be easily done by employing any of the suitable automation tools available in the market. Load testing is performed to determine a systems behavior under both normal and at peak conditions.
