Importance and purpose of test

　　(1) The importance of testing

　　 Software testing is in the whole software life cycle , Has a very critical position , The school can only be operated before the period of operation and post maintenance , Software debugging waterfall model , It is a kind of conventional operation mode , To ensure that the software is delivered to the user before , Software is normal 、 It works 、 reliable . Recently , The latest software projects believe that , A complete software lifecycle includes verification , Test whether the running result of the software is close to the expected value , Problems need to be identified as early as possible 、 solve the problem , If you can't find it early in debugging , The error will gradually spread , Finally, it leads to significant errors in the software test results .

　　 Generally speaking , For system software , Whatever the technology 、 Mode of operation , There will still be errors in the system software . New working languages , Advanced R & D technology , Efficient development and progress , It can reduce errors in the system , But it is absolutely impossible to completely eliminate the software problems , The discovery of the above errors requires a series of tests .

　　 In practical application , It is difficult to debug the software , Therefore, it is often done in a hurry or without debugging at the root , This is because during the test , Still have a lot of wrong ideas and negative work attitude , There are mainly ：

　　

　　① , Because it is easy to design and program , Make progress difficult ;

　　② Find problems in the software , Effective testing is not constructive , sometimes , And because of problems , And deny a job ;

　　③ The test work is rather boring , It didn't attract people's attention ;

　　④ Testing is a complex task 、 Patient work ;

　　⑤ Blind confidence in software systems , After finding the problem , Fear that users will doubt their R & D level .

　　 The above knowledge about software testing is very negative , It needs a new and correct understanding , So as to improve the comprehensive quality of software products .

　　 The goal is (2) Test of

　　 Suppose the main purpose of the test is to find more errors and problems , So during the test , It should be detected before the location of the wrong problem .

　　① Software testing is a system program to find problems ;

　　② Testing is to find problems in the program , It is not a problem free detection system program ;

　　③ A good test case is , It has not found any problems yet ;

　　④ A successful test is to find problems , So up to now, no other problems have been found .

　　 This view can remind the staff to find the core of the problem , It does not show that the software system can work properly . however , This kind of view is only seen from the surface of the text , May cause misunderstanding , It is considered that the function of testing is to find problems in software systems , If you don't find any mistakes, you will fail .

　　 First , Testing is not just about finding problems . After analyzing and studying the cause of the fault and the distribution of the error , It can help the staff to find problems in the software processing process . meanwhile , This kind of analysis can also help us come up with more effective 、 Reasonable detection means , So as to further improve the working efficiency of the test . after , Various problems found during the test , It's all meaningful .
