Black box testing - This type of Testing is not based on any information of inner design or coding. These Tests are based mostly on requirements and functionality.
White box testing - This is predicated 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 - essentially the most 'micro' scale of testing; to test explicit capabilities or code modules. This is typically executed by the programmer and not by testers, as it requires detailed knowledge 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 creating test driver modules or test harnesses.
Incremental integration testing - continuous testing of an application when new functionality is added; requires that varied aspects of an application's functionality be impartial sufficient to work separately before all parts of the program are accomplished, or that test drivers be developed as needed; completed by programmers or by testers.
Integration testing - testing of mixed elements of an application to determine in the event that they functioning together correctly. The 'components' may be code modules, individual applications, client and server applications on a network, etc. This type of testing is particularly relevant to consumer/server and distributed systems.
Functional testing - this testing is geared to functional necessities of an application; this type of testing needs to be carried out by testers. This doesn't mean that the programmers shouldn't check that their code works earlier than releasing it (which in fact applies to any stage of testing.)
System testing - this relies on the general necessities specifications; covers all of 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 state of affairs that imitate real-world use, equivalent to 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 a new software version is performing well enough to simply accept it for a significant testing effort. For instance, 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 normal situation to warrant further testing in its present state.
Regression testing - this is re-testing after bug fixes or modifications of the software. It is difficult to find out 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 will be said as a last testing and this was carried out based on specs of the end-user or buyer, or based mostly on use by end-customers/clients over some restricted period of time.
Load testing - this just isn'thing however testing an application below heavy loads, equivalent to testing a web site under a range of loads to find out at what point the system's response time degrades or fails.
Stress testing - the term often used interchangeably with 'load' and 'performance' testing. Additionally used to describe such tests as system functional testing while underneath unusually heavy loads, heavy repetition of certain actions or inputs, enter of large numerical values, massive complex queries to a database system, etc.
Efficiency testing - the term usually 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 done for 'user-buddyliness'. Clearly this is subjective, and will rely on the targeted end-user or customer. Person interviews, surveys, video recording of user sessions, and different techniques might be used. Programmers and testers are normally 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-user or a customer.
Comparability testing - comparing 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 because of such testing. This is typically completed by end-customers or others, but not by the programmers or testers.
Beta testing - testing when development and testing are essentially completed and closing bugs and problems should be found earlier than closing release. This is typically achieved by end-customers or others, not by programmers or testers.
