Software Testing Types: A Look At Some Great Technology
Software testing types is one of the important steps in the software development lifecycle. Testing is to find errors in the program before marketing it. Software testing is done for quality assurance. There are different levels of software testing and at each level different software testing types are used.
Test checks the correctness, completeness, security and some technical terms like maintainability, efficiency, capability, portability and usability. There are different software testing types like black box testing in which the programmer doesn’t see the code of the program, white box testing in which the programmer examines the internal structure of the program, grey box testing includes the combination of black box testing along with the knowledge of database validation, test script includes set of instructions that run automatically by a software of hardware tool.
The above software testing types described were the basic testing methods used in for small programs. There are many programs which the above tests fail so there are much more complicated testing methods for the complex programs. The above testing methods are applied for every test case .i.e. the testing is done in order like the above tests are conducted first then the other tests are conducted. In white box testing the tester has access to the internal data structure, code and algorithms. That is why unit testing is used. In unit testing the program is tested unit by unit and afterwards it is integrated all together. Another testing method is the integration testing in which the code written by different developer is tested and whichever is appropriate is integrated into the system. Another group of testing is validation and verification testing. Verification as the name suggest is to verify that the code prepared is according to the specification or not. Validation is to valid means what the customer wants.
Functional testing this test is conducted at any level for proper functionality as specified by the customer. Next is system testing it test the complete system to verify that it meets all the requirements. Acceptance testing can be conducted by end user, customer and checks that the product developed is what he wants. Acceptance testing includes two types alpha testing and beta testing. In alpha testing the code is verified at the developer’s site .i.e. the code will be tested in the developer’s computer or system. In beta testing the code will be tested at the client site .i.e. the software is allowed to be used by the customers and some outside people for testing and to verify that the software is developed according to the requirements. Feedback is the must in the beta testing because without feedback the developer will not know his mistakes so this testis conducted. Alpha and beta testing give some overview about the software like the software is portable .i.e. it can work in any environment or it can work in different system.All the software testing types mentioned above are orderly used and are the must in the development of software
