What Sorts Of Software Testing Should Be Considered

What Sorts Of Software Testing Should Be Considered

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

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

Unit testing - probably the most 'micro' scale of testing; to test particular features or code modules. This is typically done by the programmer and not by testers, because it requires detailed data of the inner program, design and code. Not at all times simply carried out unless the application has a well-designed architecture with tight code; may require growing test driver modules or test harnesses.

Incremental integration testing - continuous testing of an application when new functionality is added; requires that various points of an application's functionality be independent sufficient to work separately before all elements of the program are accomplished, or that test drivers be developed as needed; completed by programmers or by testers.

Integration testing - testing of combined components of an application to find out if they functioning collectively correctly. The 'components' may be code modules, particular person applications, client and server applications on a network, etc. This type of testing is very relevant to client/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 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 predicated on the overall necessities specs; covers all of the mixed parts of a system.

Finish-to-finish testing - this is just like system testing; entails testing of an entire application environment in a scenario that imitate real-world use, similar to interacting with a database, using 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 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 is probably not in a normal situation to warrant additional testing in its current state.

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

Acceptance testing - this may be said as a final testing and this was achieved based mostly on specifications of the tip-user or customer, or based mostly on use by end-users/prospects over some limited interval of time.

Load testing - this just isn'thing however testing an application underneath heavy loads, such as testing a web site below a range of loads to determine at what point the system's response time degrades or fails.

Stress testing - the term typically 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, massive complicated queries to a database system, etc.

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

Usability testing - this testing is finished for 'consumer-palliness'. Clearly this is subjective, and can rely upon the focused finish-consumer or customer. Consumer interviews, surveys, video recording of consumer periods, and different methods can be used. Programmers and testers are normally 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 end-person 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 end-users or others, but not by the programmers or testers.

Beta testing - testing when development and testing are essentially completed and final bugs and problems should be found earlier than final release. This is typically finished by end-customers or others, not by programmers or testers.
