Different test techniques

　　1 Coverage testing technology

　　 explain : The test coverage can show the completion of the test , It can be used as the basis for quantitative indicators in the test analysis report , The higher the test coverage, the better the effect .

　　 Coverage test can be the execution path of program code , It can also be the step of function realization ( It can be understood as the path coverage of the flow chart ).

　　 This technique can be used in any testing phase , Including unit tests 、 Integration testing 、 The system test .

　　 Any of the above test methods and techniques can be used when using this technology .

　　2 White box test and black box test technology

　　 White box testing technology (White Box Testing) The main feature of this technology is that the test object enters into the code , According to the developer's familiarity with the code and the program , In the software coding stage, the necessary parts are analyzed , Developers based on self The software test that has been carried out to understand and contact the code is called white box test . This phase of testing is dominated by software developers , Use Xunit Series of tools to test , It can include many aspects, such as function and performance .

　　 Black box testing (Black Box Testing) The main part of the test, the content of black box test, mainly includes the following aspects , But the main part is the function part . It mainly covers all functions , Can be combined with compatible , Performance test, etc , Please refer to the above for the different test types included .

　　3 Manual testing and automated testing

　　 Manual testing (Manual Testing)： That is to rely on manpower to find Bug. Methods can refer to the above test , Different tests can also be carried out according to the implementation technology and experience .

　　 Automatic test (Automation Testing) Implement... With targeted tools . Can make plans for automated testing , Write or record corresponding scripts for parts that can be tested automatically , You can add functions , Fault tolerance , Form submission, etc , You can refer to MI,Rational Or other test tools .

　　 According to authoritative software testing experience , Manual testing is still the main test method , Automated testing is not flexible enough , I won't go into details here . Microsoft's testing process 80% It was done by hand .

　　 Automatic testing can never replace manual testing , However, it is an indisputable fact that the workload of manual testing is very large .

　　4 according to RUP The standard distinguishes tests by stages

　　 Unit tests are described in detail above , There are also discussions on unit testing and integration testing , Please refer to .

　　 Integration testing is divided into functional integration testing and system integration testing , Functional integration with mutual calls , In the system environment, the influence of mutual function call, etc , The above contents can be used arbitrarily . Focus on function .

　　 The system test is based on the function realization , Compatibility can be added , Ease of use , Performance, etc.

　　 Acceptance tests may include Alpha and Beta test , I won't elaborate here .
