Performance/Load Testing

Testing to ensure that your site performs well
under all conditions

Load Testing

Load testing focuses on the ability of a system to handle increasing levels of anticipated realistic loads resulting from transaction requests generated by controlled numbers of concurrent users or processes.

Stress Testing

Stress testing focuses on the ability of a system or component to handle peak loads that are at or beyond the limits of its anticipated or specified workloads. Stress testing is also used to evaluate a system’s ability to handle reduced availability of resources such as accessible computing capacity, available bandwidth, and memory.

Scalability Testing

Scalability testing focuses on the ability of a system to meet future efficiency requirements which may be beyond those currently required. The objective of these tests is to determine the system’s ability to grow (e.g., with more users, larger amounts of data stored) without violating the currently specified performance requirements or failing. Once the limits of scalability are known, threshold values can be set and monitored in production to provide a warning of problems which may be about to arise.. In addition the production environment may be adjusted with appropriate amounts of hardware.

Spike Testing

Spike testing focuses on the ability of a system to respond correctly to sudden bursts of peak loads and return afterwards to a steady state.

Endurance Testing

Endurance testing focuses on the stability of the system over a time frame specific to the system’s operational context. This type of testing verifies that there are no resource capacity problems (e.g., memory leaks, database connections, thread pools) that may eventually degrade performance and/or cause failures at breaking points.

Concurrency Testing

Concurrency testing focuses on the impact of situations where specific actions occur simultaneously (e.g., when large numbers of users log in at the same time). Concurrency issues are notoriously difficult to find and reproduce, particularly when the problem occurs in an environment where testing has little or no control, such as production.

Capacity Testing

Capacity testing determines how many users and/or transactions a given system will support and still meet the stated performance objectives. These objectives may also be stated with regard to the data volumes resulting from the transactions.
