What Sorts Of Software Testing Ought To Be Considered

Black box testing - This kind of Testing is not based mostly on any knowledge of inner design or coding. These Tests are based mostly on necessities and functionality.

White box testing - This relies on data of the inner 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 particular capabilities or code modules. This is typically done by the programmer and not by testers, as it requires detailed information of the inner program, design and code. Not at all times simply performed 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 features of an application's functionality be independent sufficient to work separately before all elements of the program are completed, or that test drivers be developed as wanted; completed by programmers or by testers.

Integration testing - testing of mixed components of an application to determine if they functioning together correctly. The 'parts' might be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially related 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 performed 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 overall necessities specs; covers all of the combined elements of a system.

Finish-to-end testing - this is similar to system testing; entails testing of a complete application atmosphere in a situation that imitate real-world use, comparable 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 just accept it for a significant testing effort. For example, if the new software is crashing systems in every 5 minutes, making down the systems to crawl or corrupting databases, the software is probably not in a standard situation to warrant further testing in its current state.

Regression testing - this is re-testing after bug fixes or modifications of the software. It is tough to find out how a lot re-testing is required, particularly on the finish of the development cycle. Automated testing tools are very useful for this type of testing.

Acceptance testing - this could be said as a remaining testing and this was performed primarily based on specs of the tip-consumer or buyer, or based mostly on use by end-customers/customers over some restricted period of time.

Load testing - this will not behing but testing an application beneath heavy loads, reminiscent of 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 usually used interchangeably with 'load' and 'performance' testing. Additionally used to describe such tests as system functional testing while beneath unusually heavy loads, heavy repetition of certain actions or inputs, input of huge numerical values, massive advanced queries to a database system, etc.

Performance testing - the term often 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 rely on the targeted end-user or customer. Consumer interviews, surveys, video recording of consumer periods, and other methods might 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/working system/network/etc. environment.

User acceptance testing - determining if software is satisfactory to a end-consumer or a customer.

Comparison testing - evaluating software weaknesses and strengths to different competing products.

Alpha testing - testing an application when development is nearing completion; minor design modifications should still be made because of such testing. This is typically performed by end-customers or others, but not by the programmers or testers.

Beta testing - testing when development and testing are essentially completed and remaining bugs and problems have to be discovered before remaining release. This is typically finished by end-customers or others, not by programmers or testers.
