What Kinds Of Software Testing Ought to Be Considered
Black box testing - This kind of Testing is just not based on any knowledge of inside design or coding. These Tests are based mostly on requirements 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 carried out by the programmer and never by testers, as it requires detailed knowledge of the interior program, design and code. Not always easily finished unless the application has a well-designed architecture with tight code; could require growing test driver modules or test harnesses.
Incremental integration testing - continuous testing of an application when new functionality is added; requires that numerous points of an application's functionality be independent enough to work separately before all parts of the program are completed, or that test drivers be developed as wanted; finished by programmers or by testers.
Integration testing - testing of mixed parts of an application to determine if they functioning collectively correctly. The 'parts' might be code modules, particular person applications, shopper and server applications on a network, etc. This type of testing is particularly relevant to client/server and distributed systems.
Functional testing - this testing is geared to functional requirements 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 earlier than releasing it (which of course applies to any stage of testing.)
System testing - this is based on the overall requirements specifications; covers all of the mixed parts of a system.
End-to-end testing - this is similar to system testing; includes testing of an entire application environment in a situation that imitate real-world use, corresponding to interacting with a database, utilizing 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 instance, if the new software is crashing systems in each 5 minutes, making down the systems to crawl or corrupting databases, the software will not be in a standard condition to warrant further testing in its current state.
Regression testing - this is re-testing after bug fixes or modifications of the software. It's difficult to find out how a lot re-testing is required, particularly on the end of the development cycle. Automated testing instruments are very useful for this type of testing.
Acceptance testing - this might be said as a closing testing and this was completed primarily based on specs of the end-user or buyer, or based on use by finish-customers/clients over some limited interval of time.
Load testing - this is just nothing however testing an application under heavy loads, such as testing a web site under a range of loads to find out at what level the system's response time degrades or fails.
Stress testing - the term often used interchangeably with 'load' and 'efficiency' testing. Additionally used to explain such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complicated queries to a database system, etc.
Performance testing - the term typically 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 done for 'person-buddyliness'. Clearly this is subjective, and can depend upon the targeted finish-user or customer. User interviews, surveys, video recording of person classes, and different techniques may 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/working system/network/etc. environment.
Consumer acceptance testing - figuring out if software is satisfactory to a finish-user or a customer.
Comparability testing - comparing software weaknesses and strengths to different 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 achieved by end-customers or others, however not by the programmers or testers.
Beta testing - testing when development and testing are essentially completed and closing bugs and problems must be found before closing release. This is typically achieved by finish-customers or others, not by programmers or testers.
