What Sorts Of Software Testing Should Be Considered
Black box testing - This form of Testing will not be based on any data of inner design or coding. These Tests are based on requirements and functionality.
White box testing - This relies on knowledge of the inner logic of an application's code. Tests are primarily based on coverage of code statements, branches, paths, conditions.
Unit testing - probably the most 'micro' scale of testing; to test explicit capabilities or code modules. This is typically carried out by the programmer and not by testers, because it requires detailed information of the inner program, design and code. Not at all times easily executed unless the application has a well-designed architecture with tight code; could require growing test driver modules or test harnesses.
Incremental integration testing - steady testing of an application when new functionality is added; requires that numerous facets of an application's functionality be impartial sufficient to work separately earlier than all elements of the program are completed, or that test drivers be developed as needed; done by programmers or by testers.
Integration testing - testing of mixed elements of an application to find out if they functioning together correctly. The 'parts' might be code modules, particular person applications, consumer and server applications on a network, etc. This type of testing is especially 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 performed by testers. This does not imply that the programmers should not 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 requirements specifications; covers all of the mixed components of a system.
Finish-to-finish testing - this is just like system testing; includes testing of a whole application environment in a scenario that imitate real-world use, reminiscent of 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 determine whether or not a new software version is performing well enough to simply accept it for a serious 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 may 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 is troublesome to determine how a lot re-testing is required, particularly on the end of the development cycle. Automated testing instruments are very helpful for this type of testing.
Acceptance testing - this will be said as a last testing and this was finished primarily based on specs of the tip-person or buyer, or based mostly on use by end-users/customers over some limited interval of time.
Load testing - this is just nothing however testing an application beneath heavy loads, such as 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 time period usually used interchangeably with 'load' and 'performance' testing. Additionally used to explain such tests as system functional testing while underneath unusually heavy loads, heavy repetition of certain actions or inputs, enter of enormous numerical values, massive complicated queries to a database system, etc.
Performance testing - the term usually used interchangeably with 'stress' and 'load' testing. Ideally 'efficiency' testing is defined in necessities documentation or QA or Test Plans.
Usability testing - this testing is finished for 'consumer-friendliness'. Clearly this is subjective, and will depend upon the targeted finish-user or customer. Consumer interviews, surveys, video recording of person classes, and different methods could be used. Programmers and testers are usually not suited as usability testers.
Compatibility testing - testing how well the software performs in a particular hardware/software/operating system/network/etc. environment.
Consumer acceptance testing - determining if software is satisfactory to a end-consumer or a customer.
Comparison 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 on account of such testing. This is typically accomplished by end-customers or others, but not by the programmers or testers.
Beta testing - testing when development and testing are essentially accomplished and last bugs and problems have to be found before remaining release. This is typically executed by finish-users or others, not by programmers or testers.
