What Kinds Of Software Testing Ought to Be Considered
Black box testing - This kind of Testing isn't based mostly on any knowledge of inner 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 primarily based on coverage of code statements, branches, paths, conditions.
Unit testing - probably the most 'micro' scale of testing; to test particular functions or code modules. This is typically completed by the programmer and not 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; may require developing test driver modules or test harnesses.
Incremental integration testing - continuous testing of an application when new functionality is added; requires that various points of an application's functionality be unbiased enough to work separately earlier than all parts of the program are accomplished, or that test drivers be developed as wanted; executed by programmers or by testers.
Integration testing - testing of mixed parts of an application to find out if they functioning collectively correctly. The 'parts' may be code modules, individual applications, shopper and server applications on a network, etc. This type of testing is especially related 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 finished 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 is based on the overall requirements specifications; covers all of the combined parts of a system.
Finish-to-end testing - this is much like system testing; involves testing of an entire application surroundings in a situation that imitate real-world use, corresponding 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 or not a new software model 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 might not be in a normal 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 troublesome to determine how much re-testing is required, particularly at the end of the development cycle. Automated testing instruments are very useful for this type of testing.
Acceptance testing - this may be said as a remaining testing and this was achieved based mostly on specs of the top-person or customer, or primarily based on use by finish-customers/clients over some limited interval of time.
Load testing - this just isn'thing but testing an application under heavy loads, resembling 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 'performance' testing. Also used to explain such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, enter of huge numerical values, massive advanced queries to a database system, etc.
Efficiency 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 finished for 'person-friendliness'. Clearly this is subjective, and will rely on the focused end-user or customer. Consumer interviews, surveys, video recording of person periods, and other strategies might 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/operating system/network/etc. environment.
User 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 changes may still be made as a result of such testing. This is typically accomplished by end-users or others, but not by the programmers or testers.
Beta testing - testing when development and testing are essentially completed and closing bugs and problems need to be found before remaining release. This is typically finished by finish-users or others, not by programmers or testers.
