Definition of test: The purpose of program testing is to implement a process of the program in order to find errors. The task and purpose of testing can be expressed as: <br>purpose: to find errors in the program; <br>task: to find hidden errors in the program by running the program on the computer. <br>Another term related to prediction is called debugging. Its purpose and tasks can be specified as: <br>purpose: to find and correct errors; <br>task: to eliminate software failures, so as to ensure the reliable operation of the program. The relationship between testing and error correction can be illustrated with the data flow diagram in Figure 6-1. It can be seen from the figure that each test of the system is to prepare several test data, so as to be sent into the computer together with the tested program for command execution. Generally, we call the test data required for program execution once as a "Test Case". Each test case produces a corresponding "test result". But if its test result is not consistent with the "expected result" , That is to say that there is an error in the program, we need to find and correct it.

测试的定义：程序测试的目的是为了找到错误而实行程序的一个过程。测试(Testing)的任务与目的可以表现为：<br>目的：发现程序的错误；<br>任务：通过运行计算机上的程序，找到程序中隐藏的错误。<br>另一个预测的相关术语叫纠错(Debugging)。其目的以及任务可以规定为：<br>目的：找到并且纠正错误；<br>任务：解除软件的故障，从而保证程序的可靠运行。测试与纠错的关系，可以用图6-1的数据流图来说明。从图中可以看出，每一次系统的测试是要准备好若干个测试数据，从而与被测试的程序一起送入计算机进行命令执行。一般我们把程序执行一次所需要的测试数据，叫做一个“测试用例(Test Case)。其中每一个测试用所例产生相应的“测试结果”。但是如果它的测试结果与“期望结果”不一致的话，那就是说明程序中的错误是存在的，需要我们来找到并改正。

Definition of test: the purpose of program test is to find errors and implement a program process. The tasks and purposes of testing can be shown as follows:<br>Objective: to find out the mistakes of procedure;<br>Task: find hidden errors in programs by running programs on your computer.<br>Another prediction related term is debugging. Its purpose and tasks can be defined as:<br>Objective: to find and correct mistakes;<br>Task: remove the software fault, so as to ensure the reliable operation of the program. The relationship between test and error correction can be illustrated by the data flow diagram in Figure 6-1. As can be seen from the figure, each system test is to prepare several test data, so as to send them to the computer together with the tested program for command execution. In general, we call the test data needed by a program to execute once a "test case". Each of these tests produces a corresponding "test result". But if its test results are inconsistent with the "expected results", it means that the errors in the program exist and need to be found and corrected.<br>
