What Kinds Of Software Testing Ought To Be Considered

Black box testing - This kind of Testing just isn't based on any knowledge of inner design or coding. These Tests are based on necessities and functionality.

White box testing - This is predicated on knowledge of the interior logic of an application's code. Tests are primarily based on coverage of code statements, branches, paths, conditions.

Unit testing - the most 'micro' scale of testing; to test particular features or code modules. This is typically executed by the programmer and never by testers, as it requires detailed knowledge of the inner program, design and code. Not always easily done unless the application has a well-designed architecture with tight code; may require creating test driver modules or test harnesses.

Incremental integration testing - steady testing of an application when new functionality is added; requires that numerous elements of an application's functionality be unbiased sufficient to work separately earlier than all parts of the program are completed, or that test drivers be developed as wanted; finished by programmers or by testers.

Integration testing - testing of mixed parts of an application to find out in the event that they functioning together correctly. The 'parts' may be code modules, particular person applications, shopper and server applications on a network, etc. This type of testing is especially related to client/server and distributed systems.

Functional testing - this testing is geared to functional requirements of an application; this type of testing must be executed by testers. This does not imply that the programmers should not check that their code works before releasing it (which after all applies to any stage of testing.)

System testing - this is based on the overall necessities specs; covers all the combined parts of a system.

End-to-end testing - this is much like system testing; entails testing of an entire application environment in a situation that imitate real-world use, equivalent to interacting with a database, utilizing network communications, or interacting with other hardware, applications, or systems.

Sanity testing or smoke testing - typically this is an initial testing to determine whether a new software model is performing well enough to just accept it for a significant testing effort. For example, if the new software is crashing systems in every 5 minutes, making down the systems to crawl or corrupting databases, the software might not be in a traditional condition to warrant further testing in its current state.

Regression testing - this is re-testing after bug fixes or modifications of the software. It is troublesome to determine how much re-testing is needed, especially at the end of the development cycle. Automated testing instruments are very useful for this type of testing.

Acceptance testing - this may be said as a closing testing and this was performed primarily based on specs of the end-consumer or buyer, or primarily based on use by end-users/prospects over some limited period of time.

Load testing - this just isn'thing however testing an application under heavy loads, resembling testing a web site under a range of loads to find out at what point the system's response time degrades or fails.

Stress testing - the time period often used interchangeably with 'load' and 'efficiency' testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of sure actions or inputs, input of enormous numerical values, large complicated queries to a database system, etc.

Efficiency testing - the time period usually used interchangeably with 'stress' and 'load' testing. Ideally 'efficiency' testing is defined in necessities documentation or QA or Test Plans.

Usability testing - this testing is finished for 'user-buddyliness'. Clearly this is subjective, and can rely on the focused finish-user or customer. Person interviews, surveys, video recording of consumer classes, and different methods might be used. Programmers and testers are usually not suited as usability testers.

Compatibility testing - testing how well the software performs in a particular hardware/software/working system/network/etc. environment.

Person acceptance testing - determining if software is satisfactory to a end-person or a customer.

Comparison testing - comparing software weaknesses and strengths to different competing products.

Alpha testing - testing an application when development is nearing completion; minor design changes should be made because of such testing. This is typically executed by finish-customers or others, but not by the programmers or testers.

Beta testing - testing when development and testing are essentially accomplished and last bugs and problems have to be found before final release. This is typically performed by finish-users or others, not by programmers or testers.
