Xuan computer - storage unit Ul towel, and then by the computer - the execution unit

Ut::. Then, the tester confirms whether the reliance passes according to the execution status of the display device 12 or the display unit 113. In order to develop a variety of test programs that conform to different standard operating procedures... and program developers must spend a lot of time:: work. The reason is that although the tester knows best: such as = wide = standard operating procedures to test the display device, but there is no such force. The other 4' display device control usually has to be replaced by a lower-order programming language (such as a combined language) or a medium-level programming language (> in a more complicated and difficult to understand application No. 96112418 (revised date: 77). )write. On the other hand, programmers who have programming skills but are not familiar with how to develop test programs that meet the testing requirements must communicate with the testers several times before they can understand the direction of the programming for subsequent work. As mentioned above, the development process of the test program cannot be performed efficiently, resulting in a new test method that cannot be immediately added to the work of automated test. Furthermore, when a test program is developed, if the tester wants to make minor modifications to the test program according to the actual application, the program designer must be requested to complete the modification. As mentioned above, in order to effectively improve the efficiency of automated testing, and to enable testers to develop, modify and verify test methods that meet their needs, it is necessary to seek solutions. SUMMARY OF THE INVENTION That is, an automated test is provided. Therefore, the primary object of the present invention is to show a method of placement.

In the basin, = Wen Lai 2U is stored in the form of a file file, and the tester; in accordance with the requirements of the actual test 'by the default rules 99. 7.- No. 96114418 application replacement page (amended date: 99 July of the year) 211. In order to enable the tester to easily and conveniently write the file file 211, the preset rule is formed by a defined test language mode, and has a plurality of preset instructions and a plurality of operation elements corresponding to the preset instructions, the preset The rules are specifically designed as a series of actions that may be used to test the display device 3. The preset commands cover commonly used commands (Command), Operation (Input), and Input & Output, and allow Testers write in near-natural language usage. For example, the display device 3 to be tested is a television. If the tester wants to test whether the menu of the television can correctly adjust the position in the screen, according to the preset rule, the preset instruction is preceded by the operation element. After the form is written, the file file 211 can be roughly written as:

KeyDriver Vkey_Driver 1 “VirtualKey” MENU (Analog presses the menu button to turn on the TV 7 DOWN (the seventh item in the above three columns of the simulation selection menu is set to ENTER (simulate press the enter button to enter the menu) middle
