What Kinds Of Software Testing Should Be Considered
Black box testing - This kind of Testing is not primarily based on any data of internal design or coding. These Tests are based mostly on requirements and functionality.
White box testing - This is predicated on knowledge of the interior logic of an application's code. Tests are based mostly on coverage of code statements, branches, paths, conditions.
Unit testing - essentially the most 'micro' scale of testing; to test specific features or code modules. This is typically performed by the programmer and not by testers, as it requires detailed information of the inner program, design and code. Not all the time easily performed unless the application has a well-designed architecture with tight code; might require creating test driver modules or test harnesses.
Incremental integration testing - steady testing of an application when new functionality is added; requires that varied features of an application's functionality be unbiased enough to work separately earlier than all parts of the program are accomplished, or that test drivers be developed as wanted; performed by programmers or by testers.
Integration testing - testing of mixed parts of an application to determine in the event that they functioning collectively correctly. The 'parts' will be code modules, particular person applications, shopper and server applications on a network, etc. This type of testing is especially related to shopper/server and distributed systems.
Functional testing - this testing is geared to functional necessities of an application; this type of testing ought to be done by testers. This doesn't mean that the programmers shouldn't check that their code works before releasing it (which in fact applies to any stage of testing.)
System testing - this is based on the general necessities specifications; covers all of the mixed components of a system.
End-to-finish testing - this is much like system testing; involves testing of a complete application surroundings in a scenario that imitate real-world use, such as 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 or not a new software version is performing well sufficient to simply 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 might not be in a standard situation to warrant additional testing in its present state.
Regression testing - this is re-testing after bug fixes or modifications of the software. It is difficult to determine how a lot re-testing is required, particularly at the end of the development cycle. Automated testing instruments are very helpful for this type of testing.
Acceptance testing - this may be said as a closing testing and this was finished based mostly on specs of the tip-person or buyer, or primarily based on use by finish-users/prospects over some limited interval of time.
Load testing - this shouldn't behing however testing an application underneath heavy loads, equivalent to testing a web site beneath a range of loads to determine at what level the system's response time degrades or fails.
Stress testing - the time period typically used interchangeably with 'load' and 'efficiency' testing. Additionally used to explain such tests as system functional testing while beneath unusually heavy loads, heavy repetition of sure actions or inputs, input of huge numerical values, massive complicated queries to a database system, etc.
Performance testing - the term often 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 'consumer-buddyliness'. Clearly this is subjective, and will rely upon the focused end-person or customer. Consumer interviews, surveys, video recording of consumer sessions, and different methods 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.
Comparability testing - evaluating software weaknesses and strengths to other competing products.
Alpha testing - testing an application when development is nearing completion; minor design adjustments may still be made as a result of such testing. This is typically executed by finish-users or others, but not by the programmers or testers.
Beta testing - testing when development and testing are essentially accomplished and remaining bugs and problems need to be found earlier than remaining release. This is typically performed by finish-users or others, not by programmers or testers.
