That is, the test program of the present invention is, as shown in FIG. 1, a test command file written in a predetermined language and a test for reading the test command file and performing the print control of the present invention. It is composed of a control unit.

In the test command file, a start code (S) and an end code (E) are paired for each test item, and the test contents described in a predetermined description language are filed.

In order to perform a test, the source files of the test program are assembled / compiled / linked to create a test control unit which is an executable file. The test command file is stored in the same medium as the test control unit, loaded into the test system, and executed. {Refer to the data flow in Fig. 3 and carrying of media} The test system operates as follows.

That is, since the test control section comprises a test procedure creation section and a command code conversion section, first, the test procedure creation section reads one test item from the test command file to execute the test procedure. That is, an instruction string for each instruction is created and stored in the memory.
{Refer to processing steps 100 to 103 in FIG. 2} Next, the test procedure is printed from the memory via the input / output driver, and the test procedure is converted into an execution command string by the command code conversion unit. Then, a print test is performed via the input / output driver, and the test result is printed in a pair with the already printed test procedure. {Printing results on the test target printer device of FIGS. 1 and 3, processing steps of FIG.
