What Sorts Of Software Testing Ought To Be Considered

What Sorts Of Software Testing Ought To Be Considered

Black box testing - This sort of Testing isn't primarily based on any information of inner design or coding. These Tests are based on necessities and functionality.

White box testing - This is predicated 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 explicit features or code modules. This is typically accomplished by the programmer and not by testers, because it requires detailed information of the interior program, design and code. Not at all times easily achieved unless the application has a well-designed architecture with tight code; could require developing test driver modules or test harnesses.

Incremental integration testing - steady testing of an application when new functionality is added; requires that numerous points of an application's functionality be independent sufficient to work separately before all elements of the program are accomplished, or that test drivers be developed as wanted; finished by programmers or by testers.

Integration testing - testing of mixed elements of an application to determine if they functioning together correctly. The 'components' may be code modules, individual applications, consumer and server applications on a network, etc. This type of testing is especially relevant to shopper/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 does not imply that the programmers shouldn't check that their code works before releasing it (which of course applies to any stage of testing.)

System testing - this is based on the general requirements specs; covers all of the mixed elements of a system.

End-to-end testing - this is much like system testing; entails testing of a complete application surroundings in a scenario that imitate real-world use, equivalent 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 determine whether a new software version is performing well enough to just accept it for a significant 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 is probably not in a standard condition 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 determine how a lot re-testing is required, especially at the end of the development cycle. Automated testing tools are very helpful for this type of testing.

Acceptance testing - this may be said as a final testing and this was finished based mostly on specifications of the end-user or customer, or based on use by finish-customers/customers over some limited interval of time.

Load testing - this isn'thing however testing an application under heavy loads, reminiscent of testing a web site beneath a range of loads to determine at what level the system's response time degrades or fails.

Stress testing - the term usually used interchangeably with 'load' and 'performance' testing. Also used to describe such tests as system functional testing while underneath unusually heavy loads, heavy repetition of sure actions or inputs, input of enormous numerical values, massive complex queries to a database system, etc.

Efficiency testing - the time period often 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 finished for 'consumer-palliness'. Clearly this is subjective, and will depend on the focused end-person or customer. Consumer interviews, surveys, video recording of person periods, and other techniques could be used. Programmers and testers are usually 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 - figuring out if software is satisfactory to a finish-user or a customer.

Comparison 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 performed by finish-users or others, however not by the programmers or testers.

Beta testing - testing when development and testing are essentially accomplished and remaining bugs and problems need to be discovered before remaining release. This is typically done by finish-customers or others, not by programmers or testers.
