Performance testing is multi-pronged and covers the numerous operational parameters, which an application needs to meet to be suitable for the proposed environment. The goal of performance testing is not to find bugs but to identify bottlenecks which may hamper the execution of a perfectly good piece of code.

Performance Testing
M easures an application against a clearly defined set of performance goals which the application is expected to meet.

Load Testing
Load Testing is performed to identify and isolate bottlenecks by emulating n-number of users interacting with an entire application or by editing a high-volume document to identify the endurance limit of a word processor.

Stress Testing
M easures the ability of a system to recover from component failure. It observes the system’s reaction to attempts to break it down by overwhelming or taking away resources.

Regression Testing
Regression testing is the process of testing changes to applications/products to make sure that the older applications / products still work with the new changes.

Component Testing
Subsystem components comply with the specifications.

Compatibility Testing
Compatibility testing measures application compatibility with other platforms & applications.
