What Varieties Of Software Testing Should Be Considered

Black box testing - This kind of Testing will not be primarily based on any knowledge of inside design or coding. These Tests are primarily based on necessities and functionality.

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

Unit testing - probably the most 'micro' scale of testing; to test explicit features or code modules. This is typically done by the programmer and never by testers, as it requires detailed information of the interior program, design and code. Not at all times simply executed unless the application has a well-designed architecture with tight code; could require growing test driver modules or test harnesses.

Incremental integration testing - steady testing of an application when new functionality is added; requires that various facets of an application's functionality be independent enough to work separately earlier than all components of the program are completed, or that test drivers be developed as wanted; completed by programmers or by testers.

Integration testing - testing of combined elements of an application to find out in the event that they functioning together correctly. The 'components' may be code modules, individual applications, consumer and server applications on a network, etc. This type of testing is especially relevant to consumer/server and distributed systems.

Functional testing - this testing is geared to functional requirements of an application; this type of testing must be accomplished by testers. This doesn't mean that the programmers should not check that their code works before releasing it (which in fact applies to any stage of testing.)

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

End-to-end testing - this is just like system testing; includes testing of a complete application setting in a situation that imitate real-world use, comparable to interacting with a database, utilizing network communications, or interacting with different hardware, applications, or systems.

Sanity testing or smoke testing - typically this is an initial testing to determine whether or not a new software model is performing well enough to accept it for a major 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 will not be in a traditional situation 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 a lot re-testing is needed, especially on the finish of the development cycle. Automated testing tools are very helpful for this type of testing.

Acceptance testing - this could be said as a last testing and this was achieved based on specifications of the tip-consumer or buyer, or primarily based on use by end-users/prospects over some limited interval of time.

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

Stress testing - the term 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 certain actions or inputs, input of enormous numerical values, giant advanced queries to a database system, etc.

Performance testing - the term 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 completed for 'user-friendliness'. Clearly this is subjective, and can depend upon the targeted finish-person or customer. User interviews, surveys, video recording of user classes, and other strategies might be used. Programmers and testers are often not suited as usability testers.

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

Consumer acceptance testing - figuring out if software is satisfactory to a finish-user or a customer.

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

Alpha testing - testing an application when development is nearing completion; minor design adjustments should be made because of such testing. This is typically carried out by end-customers or others, however not by the programmers or testers.

Beta testing - testing when development and testing are essentially accomplished and final bugs and problems must be found earlier than remaining release. This is typically completed by finish-users or others, not by programmers or testers.
