Black box testing - This form of Testing is not based on any data of internal design or coding. These Tests are based mostly on necessities and functionality.
White box testing - This relies on information of the inner logic of an application's code. Tests are based mostly on coverage of code statements, branches, paths, conditions.
Unit testing - the most 'micro' scale of testing; to test explicit capabilities or code modules. This is typically finished by the programmer and never by testers, because it requires detailed data of the inner program, design and code. Not all the time simply carried out unless the application has a well-designed architecture with tight code; might require developing test driver modules or test harnesses.
Incremental integration testing - continuous testing of an application when new functionality is added; requires that various aspects of an application's functionality be independent enough to work separately earlier than all parts of the program are completed, or that test drivers be developed as needed; accomplished by programmers or by testers.
Integration testing - testing of mixed elements of an application to find out in the event that they functioning together correctly. The 'elements' might be code modules, particular person applications, shopper and server applications on a network, etc. This type of testing is particularly related to client/server and distributed systems.
Functional testing - this testing is geared to functional requirements of an application; this type of testing needs to be performed by testers. This doesn't mean that the programmers should not check that their code works before releasing it (which of course applies to any stage of testing.)
System testing - this is predicated on the general requirements specs; covers all the combined components of a system.
End-to-finish testing - this is just like system testing; includes testing of an entire application atmosphere in a situation that imitate real-world use, resembling interacting with a database, utilizing network communications, or interacting with different hardware, applications, or systems.
Sanity testing or smoke testing - typically this is an preliminary testing to find out whether a new software version is performing well sufficient to accept it for a significant testing effort. For example, if the new software is crashing systems in each 5 minutes, making down the systems to crawl or corrupting databases, the software might not be in a traditional condition to warrant additional testing in its current state.
Regression testing - this is re-testing after bug fixes or modifications of the software. It's troublesome to determine how much re-testing is needed, particularly at the end of the development cycle. Automated testing tools are very helpful for this type of testing.
Acceptance testing - this will be said as a closing testing and this was carried out based on specifications of the tip-consumer or buyer, or primarily based on use by end-users/customers over some limited interval of time.
Load testing - this isn'thing but testing an application underneath heavy loads, corresponding to testing a web site below a range of loads to find out at what point the system's response time degrades or fails.
Stress testing - the term 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, enter of huge numerical values, massive complex queries to a database system, etc.
Performance testing - the term often 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 completed for 'person-friendliness'. Clearly this is subjective, and can depend upon the targeted end-user or customer. Consumer interviews, surveys, video recording of person sessions, and different strategies 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 - determining if software is satisfactory to a finish-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 changes should still be made because of such testing. This is typically completed by finish-customers or others, but not by the programmers or testers.
Beta testing - testing when development and testing are essentially completed and ultimate bugs and problems should be discovered earlier than last release. This is typically carried out by finish-customers or others, not by programmers or testers.
