What Kinds Of Software Testing Should Be Considered

What Kinds Of Software Testing Should Be Considered

Black box testing - This kind of Testing just isn't based on any knowledge of inner design or coding. These Tests are based mostly on requirements 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 particular capabilities or code modules. This is typically executed by the programmer and never by testers, as it requires detailed knowledge of the interior program, design and code. Not always simply carried out unless the application has a well-designed architecture with tight code; might require growing test driver modules or test harnesses.

Incremental integration testing - continuous testing of an application when new functionality is added; requires that varied facets of an application's functionality be impartial sufficient to work separately earlier than all parts of the program are accomplished, or that test drivers be developed as needed; finished by programmers or by testers.

Integration testing - testing of mixed parts of an application to determine if they functioning collectively correctly. The 'parts' could be code modules, individual applications, client and server applications on a network, etc. This type of testing is very relevant to shopper/server and distributed systems.

Functional testing - this testing is geared to functional requirements of an application; this type of testing should be completed by testers. This doesn't suggest that the programmers shouldn't check that their code works before releasing it (which in fact applies to any stage of testing.)

System testing - this relies on the overall requirements specs; covers all the combined parts of a system.

End-to-finish testing - this is much like system testing; entails testing of an entire application surroundings in a situation that imitate real-world use, such as 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 determine whether or not a new software model is performing well sufficient 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 normal 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 troublesome to determine how much re-testing is needed, especially at the finish of the development cycle. Automated testing tools are very useful for this type of testing.

Acceptance testing - this might be said as a remaining testing and this was completed primarily based on specs of the top-person or customer, or primarily based on use by end-users/customers over some limited interval of time.

Load testing - this is just nothing however testing an application under heavy loads, comparable to 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 usually used interchangeably with 'load' and 'efficiency' testing. Additionally used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, enter of enormous numerical values, giant complicated queries to a database system, etc.

Efficiency testing - the time period often 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 'person-friendliness'. Clearly this is subjective, and can depend on the focused end-consumer or customer. User interviews, surveys, video recording of consumer periods, and different methods will 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/working system/network/etc. environment.

Consumer acceptance testing - determining if software is satisfactory to a finish-consumer 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 should still be made on account of such testing. This is typically done by end-customers or others, but 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 earlier than last release. This is typically achieved by end-customers or others, not by programmers or testers.
