进行一次系统测试，就把系统中所有的错误都发现出来的可能行几乎是为零的。

Perform a system test to find out that all possible errors in the system are almost zero. The software needs to be tested again and again, and updated and developed continuously in order to perfect a software. Finding and finding out bugs that can be found in the current system is the core merit of system testing. <br>The key to how to judge the success of the test done by the system is to be able to find vulnerabilities that occur in the process from release to use all the time, but this kind of error is definitely a kind of vulnerability that must exist in practice. There are two main test methods used by testers, black box and white box. Testing the functional requirements of the software is the work of black box testing. The purpose is to find out the lack of functional requirements, access the software database, test the performance, and start and end the function of the error. <br>To compare and judge the work of black box and testing, this chapter mainly uses black box testing. Test from login verification, management of grain warehouse management information and grain information addition to verify whether the software can achieve the function that can operate in the actual market.

A system test makes it almost zero for all errors in the system. Software to be tested, one after another in quenching, update and development constantly exchange, in order to improve a software. Discovering and identifying bugs that can be found in the current system is the core function of system testing.<br>The key to determining whether a system test is successful is the ability to identify vulnerabilities that occur in the process from the system to the time it has been used, but this error is a vulnerability that must actually exist. There are two main methods of testing used by testers, black box and white box. Testing the functional requirements of software is the work of black box testing, which is aimed at finding the missing functional requirements, accessing the software database, testing performance, and just-starting and ending the function of errors.<br>Comparing the work of judging the black box and the test, this section mainly uses the black box test. Test from login verification, granary management information management, and food information addition to verify that the software is up to the point where it can operate in the real market.

After a system test, all the errors in the system are found out and the possible line is almost zero. In order to improve a software, it is necessary to test, refine, update and develop the software. Finding and finding out the bugs that can be found in the current system is the core function of system testing.<br>The key point of how to judge whether the system test is successful or not is to find the loopholes in the process from the system release to the whole use, but this kind of error must be a kind of loophole in fact. There are two main testing methods used by testers: black box and white box. The test of software functional requirements is the work of black box test. The purpose is to find out the lack of functional requirements, access to the database of software, test the performance, start and end the wrong functions.<br>In this chapter, the black box test is mainly used. From the log in verification, the management of the general manager information of the granary and the addition of the grain information, test whether the software can achieve the function of operating in the actual market.
