Performance TestingThis type of testing is used to determine that thethroughput requirements and response time can be met.Stress TestingThis type of testing is used to monitor thebehavior of the system under critical loads.Security TestingDoes the system comply with the requirementsoutlined in the specifications? It is clear that the military system must havehigher level of security testing than web applications.System Testing System Testing is a testing an integrated systemto verify compliance with required conditions. In essence, this means testingthe system of related components after testing individual elements separately.(A component is the smallest part which has its own individual specification.)System testing is divided into two parts, functional and non-functionalsoftware testing.  Functional testing isbased on providing the correct work of the system. The aim of non-functionalsystem is a solving of problems not directly connected to the functions orprocesses that system can execute.For instance a function of the cash machine may bethe issuance of the cash.  Thenon-functional demand is that the issuance of the cash should be carried outsafely.Certainly a component can have functional and nospecial features. In the example with cash machine authorization is required inboth cases.  System testing mustintegrate all the functions together.You can review the examples of non-functionalrequirements below.UsabilityTestingUsability testing is aimed at simplicity and easewith which a customer can learn the system and manipulate with it.  Examples of techniques take in the heuristictesting (based on experience) and expert led focus groups.Load TestingThe aim of load testing is to check whether thesystem can meet the specified levels.  Itis worth noting that when testing, to look at both the average load, but alsothe spike level.  Load Testing is verysimilar to stress testing.PerformanceTestingPerformance Testing is carried out to compare thedegree of similarity a system or component with the components determinedpreviously. For example - the amount of airline tickets that can be issued foran hour.Stress TestingIt is performed by the research way to determinethe limit level of the loading. The system works before a failure occurs, andthus defines a point of no return.Storage TestingThis kind of testing is used to determine thedegree of conformance of the system and specific storage purposes.Documentation TestingTesting is directed to work on the technical documentationthat came in complementary with the software. This stage is required to help with installation instructions andmanuals.Installability TestingIt determines the probability of correctinstallation of the software and processing all the potential errorsaccurately.Web FunctionalityTestingIt is used to check for broken links, browsercompatibility and multi-tiered architectures.Recovery TestingIs it possible to protect the system fromdamage?  All levels of errors should bebuilt on the freezing of a system or its complete failure. An extreme exampleof recovery would be to imitate a complete damage of the system.  For example when the communication system canbe overloaded because of disastrous accident(September 11th 2001).
