What Kinds Of Software Testing Should Be Considered

What Kinds Of Software Testing Should Be Considered

Black box testing - This form of Testing is not based mostly on any data of inside design or coding. These Tests are based on requirements and functionality.

White box testing - This is based 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 carried out by the programmer and never by testers, because it requires detailed information of the interior program, design and code. Not all the time simply finished unless the application has a well-designed architecture with tight code; may require developing test driver modules or test harnesses.

Incremental integration testing - continuous testing of an application when new functionality is added; requires that varied features of an application's functionality be impartial enough to work separately before all parts of the program are completed, or that test drivers be developed as needed; done by programmers or by testers.

Integration testing - testing of mixed components of an application to determine in the event that they functioning collectively correctly. The 'components' might be code modules, individual 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 necessities of an application; this type of testing ought to be finished 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 predicated on the general requirements specifications; covers all the combined components of a system.

End-to-end testing - this is much like system testing; includes testing of a whole application atmosphere in a scenario that imitate real-world use, akin to interacting with a database, using network communications, or interacting with different hardware, applications, or systems.

Sanity testing or smoke testing - typically this is an initial testing to find out whether a new software model is performing well enough to simply 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 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 tough to determine how a lot re-testing is required, especially on the finish of the development cycle. Automated testing instruments are very useful for this type of testing.

Acceptance testing - this could be said as a closing testing and this was completed based mostly on specifications of the top-user or customer, or primarily based on use by finish-customers/clients over some restricted interval of time.

Load testing - this is just nothing but testing an application under heavy loads, resembling 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. Additionally used to explain such tests as system functional testing while beneath unusually heavy loads, heavy repetition of certain actions or inputs, input of enormous numerical values, large advanced queries to a database system, etc.

Efficiency testing - the term typically used interchangeably with 'stress' and 'load' testing. Ideally 'performance' testing is defined in necessities documentation or QA or Test Plans.

Usability testing - this testing is completed for 'consumer-good friendliness'. Clearly this is subjective, and will depend on the focused end-person or customer. Consumer interviews, surveys, video recording of person sessions, and other methods might 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.

Person acceptance testing - determining if software is satisfactory to a end-consumer 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 modifications should still be made on account 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 completed and final bugs and problems have to be found before remaining release. This is typically done by end-customers or others, not by programmers or testers.
