What Kinds Of Software Testing Should Be Considered

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

White box testing - This is predicated on knowledge of the internal 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 completed by the programmer and never by testers, as it requires detailed knowledge of the interior program, design and code. Not always simply finished unless the application has a well-designed architecture with tight code; could require creating test driver modules or test harnesses.

Incremental integration testing - continuous testing of an application when new functionality is added; requires that numerous facets of an application's functionality be independent enough to work separately earlier than all parts of the program are accomplished, or that test drivers be developed as needed; done by programmers or by testers.

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

Functional testing - this testing is geared to functional necessities of an application; this type of testing must be executed by testers. This doesn't suggest that the programmers shouldn't 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 of the combined parts of a system.

End-to-finish testing - this is similar to system testing; entails testing of a whole application setting in a situation that imitate real-world use, similar 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 find out whether a new software version is performing well enough to accept it for a serious 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 may not be in a traditional condition to warrant additional testing in its present state.

Regression testing - this is re-testing after bug fixes or modifications of the software. It's difficult to find out how much re-testing is needed, especially on the end of the development cycle. Automated testing instruments are very useful for this type of testing.

Acceptance testing - this could be said as a ultimate testing and this was carried out based mostly on specs of the tip-user or buyer, or based mostly on use by finish-customers/customers over some limited period of time.

Load testing - this is nothing however testing an application under heavy loads, corresponding to testing a web site under a range of loads to determine at what point the system's response time degrades or fails.

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

Performance testing - the term usually used interchangeably with 'stress' and 'load' testing. Ideally 'efficiency' testing is defined in requirements documentation or QA or Test Plans.

Usability testing - this testing is done for 'consumer-palliness'. Clearly this is subjective, and can depend upon the focused end-user or customer. User interviews, surveys, video recording of consumer sessions, and different methods will be used. Programmers and testers are often not suited as usability testers.

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

Consumer acceptance testing - figuring out if software is satisfactory to a end-consumer or a customer.

Comparability testing - evaluating software weaknesses and strengths to different competing products.

Alpha testing - testing an application when development is nearing completion; minor design adjustments may still be made because of such testing. This is typically done by end-users or others, but not by the programmers or testers.

Beta testing - testing when development and testing are essentially completed and closing bugs and problems have to be discovered earlier than last release. This is typically achieved by finish-users or others, not by programmers or testers.
