Function of interface test

　　 Function of interface test

　　 The English of interface test is interface testing, An interface test between components of a test system . The benefits of interface testing ： Because the interface test code itself is used junit( Of course, the types of interfaces are different , Is not necessarily Junit To achieve ) To achieve , It belongs to the field of automated testing , Therefore, it must also include the inherent advantages of automated testing .

　　1) Improve test quality

　　 The process of software development is a process of continuous integration and improvement , And every improvement can bring in New bug, So when a piece of software , Or all of them , We need to retest the software products . The purpose is to verify that the modified product meets the requirements , And when there's no automated test code , Often for a variety of reasons , The return is inadequate , Lead to bug missing .

　　2) Improve test efficiency

　　 The scale of software system is more and more large , More and more function points , Self testing by developers or manual testing by testers is very time-consuming and tedious , It will lead to the low efficiency of testing , And automated testing just solves these time-consuming and tedious tasks , When the function of the external interface is unchanged , Reached a writing , The effect of permanent use .

　　

　　

　　3) Improve test coverage

　　 It's hard to test deeper exceptions and security issues through manual testing , Through some auxiliary testing tools , Can analyze the code coverage , Improve the depth of testing by increasing coverage .

　　4) Better reproduction of software defects

　　 Because every execution is the same code , Once the code goes wrong , There must be a return to error ;

　　5) Better positioning mistakes

　　 Because interface testing is a bottom-up test , So a quantity goes wrong , It's very easy to make mistakes in positioning , Not like system testing , Once you have Bug, Several layers of validation are required to determine the location of the error ;

　　6) Reduce modification bug The cost of interface testing

　　 Basically working in parallel with the developer's coding , So finding problems is a lot earlier than system testing , So there's less modification bug Cost of .

　　7) Enhance the cooperation between testers and developers

　　 Test engineer to better carry out the work , Need to have in-depth understanding and practice of development technology , With more communication with development engineers .

　　8) Reduce the risk of project not being released on time

　　 Because interface testing has been involved very early , The core modules of the project code have been tested in detail before they are submitted to the system test , Must speed up system testing time , So as to ensure the timely release of the project ;

　　9) Improve the skills of testers

　　 Do interface testing must understand the development process and some development skills of developers , You also need to know how to use test tools and test ideas , Improve the technical added value of testers , Improved their own competitiveness .

　　10) To standardize the project development process

　　 To interface , It needs perfect documents to guarantee , No test documentation , Interface testing will be difficult , Interface testing will increase the output of development process standardization , And standardized output also ensures the quality of the project .
