Description

DETAILED DESCRIPTION OF THE INVENTION {a) Technical Field The present invention relates to a program testing system in which a computer operating online tests a program executed in another computer.

‘b} Conventional technology FIG. 1 shows the configuration of a conventional computer system.

In the figure, A is a large computer that operates online. For convenience, this large computer A is called the first computer or host (HO).
ST) It is called a computer. A' is a communication front-end processor, and a plurality of remote concentrators, T, &, B3. …
"Connect Bn. Of these multiple remote concentrators B, B2, B3...Bn, B3 will be explained as a representative. This remote concentrator B3 has a magnetic disk device, a magnetic tape device, a card reader, a line printer, etc. Multiple input/output devices C,, C2...Cn
and terminal devices D,, D2...Dn are coupled. Second
The figure shows the program creation process by the system in Figure 1, in which steps 1 to 4 are performed by host computer A, and steps 5 and 6 are performed using a second computer (target computer) not shown. . first,
I will explain step 1 in more detail.

In step 1, the program operates the terminal device D and inputs the program source code written by the actual program.
Input is from terminal device D or input/output equipment C,,C2...C
This can be done from any of n. The input code is sent to host computer A via remote concentrator B and front end processor A', and is recorded in a working file (for example, a magnetic disk drive) of host computer A. A desired line of the recorded code can be displayed on the CRT screen in the terminal device D by sending a command from the terminal device D using the operating system controlling the host computer A. By inputting some commands prepared in advance from the terminal device D, you can change part of the code previously recorded on the host computer A, add new code, or change the code previously recorded on the host computer A. You can edit it by adding other code. The above is the step-by-step work performed by the programmer. Next, the completed source code is compiled (step 2) or assembled (step 3) using commands from the terminal device ○, and grammatical errors are checked.

If there is an error in this code, go back to step 1 and correct it, then proceed to step 4. In step 4, the host computer A simulates execution on the target computer (not shown) according to the command from the terminal device D,
Check for errors. If there are any errors, go back to step one and correct them. Error messages in steps 2, 3, and 4 are output to terminal D or input/output device C. Steps 2 and 3 when you run out of effusive
Record the generated binary code on a recording medium.
Next, in step 5, the code on this recording medium is electrically transferred or transported via a communication line, and is loaded and linked (linked from the previous page) from the input device (not shown) of the target computer to the target computer. (combining code into a program on the target computer).

In step 6, the program tested in step 4 is executed on the target computer to further check for errors.

The above-mentioned conventional techniques have the following drawbacks. {i} Since the test in step 4 is to simulate the execution of the target computer on the host computer, it takes a long time to execute, and a sufficient test cannot be expected.

[Low Step 1 to Step 4 and Step 5]
, there is no system connection between step 6,
Therefore, the host computer and the host computer must be managed and operated separately.

Furthermore, since manual work is required to connect both parts, productivity decreases. {c'Purpose The present invention was made to eliminate the above-mentioned drawbacks of the conventional technology.It connects multiple types of target computers to a remote concentrator via a distributor, and tests programs using the idle time of each target computer. The purpose of the present invention is to provide a program testing system that can perform the following tasks.

'd} Description of one embodiment of the invention The system of the present invention is shown in FIG.

In FIG. 3, parts corresponding to those shown in FIG. 1 are given the same reference numerals to avoid duplication of explanation. A distributor E as a controller is connected to the remote concentrator &, and multiple types of target computers F,
, F2...Fn are combined. The distributor E receives information sent from the host computer A and the target computer F.
,,F2...Receives information sent from Fn,
Perform work to send people to their destinations. The target computer F. , F2...Fn may be of the same model or different models.

For example, it may be a minicomputer, an office computer, or a microcomputer. Moreover, these F,, F2...Fn are not provided exclusively for this system, but are scattered around the location where this system is installed, and perform daily tasks such as production management. It may be a computer that is currently running.
The present invention is directed to these target computers F, , F2...Fn.
The idle time is used. For this purpose, each target computer F, F2...Fn must already be operating under the control of a known free time system. A free time system is a variation of an online, real-time system that processes fixed online real-time jobs in the front background, while freeing up idle time (online free time) that occurs during processing for completely different user jobs. refers to something.

An example of this free time system is Toshiba Review 197
It was published as "TOSBAC 4-dish real-time control software" in the November issue of 6 King. A computer with the function of this free time system provides the following conveniences so that the user can easily utilize this idle time. That is, in FIG. 4, the demand function of a device or communication control device that wants to input or output data from the external Z to a target computer having a free time system is called SYSIN. An operator's input/output request is called a demand, and this demand is satisfied when the operator presses a push button or a break key. A device or device that performs ZSYSIN is called a SYSIN device.

When SYSIN is present, the target computer is interrupted, and subsequently the JCL input by the operator is read and decoded from the SYSIN device. JCL is Lob C.
Ontrol Lang is an abbreviation for 2 operators and is a command word used to express the content of the work they wish to do during the idle time of the target computer. Based on the decrypted results, the target computer uses the idle time to execute the work until an interrupt is issued to finish or cancel it. This concludes the explanation of FIG.

By the way, among the tasks that can be requested by JCL, those related to the present invention are... Reading of binary code (BIN3READ)'o) Binding of the read binary code to the operating system (LOAD)
1 Test (TEST) 8 Message output (MESOUT) 3 etc.

FIG. 5 shows the procedure for using the system according to the present invention, and steps b, c and d are respectively steps 1 of FIG.
, 3 and 2.

The binary code generated in step d or c is sent to the target computers F, F2, . . . , Fn via the front end processor A', remote concentrator B3, and distributor E shown in FIG. In step f, a JCL called BINREAD is input from the terminal device D and transferred to the target computer. Furthermore, JC called LOAD
Combine with the code in the target computer using L. Then T.E.
A JCL called ST is input from the terminal device D, and this code is combined according to the JCL specifications and executed simultaneously on the target computers F,, F2, . . . , Fn for testing.
Next, input the JCL called MSEOUT from the terminal device ○, record the test results on the host computer A through the distributor E, remote concentrator B, and front end processor A', and record the test results on the host computer A through the distributor E, remote concentrator B, and front end processor It is displayed on the terminal device D via the terminal device D. In step a, the text of the source code handled in steps b and below is transferred from the keyboard, cassette tape, floppy disk, etc. attached to the terminal device D to the file system of the host computer A via the remote concentrator B3 and front-end processor A'. Register and record.

Further, in step e, an arbitrary code selected from the binary code library of the host computer A and the binary code generated in step c or step d are linked according to instructions from the terminal device D.

In the final step g, the binary code completed in step f is transferred to the computer connected to the distributor E and shipped to the customer via the host computer A, front-end processor A', remote concentrator B3, and the distributor E, and loaded. and link.

{e} Other embodiments {ee} In the above explanation, target computers F,, F2...
I mentioned that Fn has a free time system and handles other online front-end jobs such as production management at the same time.

As a modification to this, target computers F,,F
2...There is an example in which Fn is used exclusively for the purpose of testing this system.

In this case, various resources used in the online job (for example, registers and memory) can be used exclusively, so that testing can be performed with even higher efficiency. {o} In the system shown in Fig. 3, the target computers F,, F2...Fn are connected to the distributor B in a star shape, but as shown in Fig. 6, F is set to known data for f. They can also be connected in a ring by highways.

In FIG. 6, m is a data highway, h,, h2...
hn is a data highway terminal station.

{f} Effect The simulation shown in Figure 2 (which is extremely inefficient and requires no complete testing) by adding a distributor and a target computer to the conventional system shown in Figure 1, which enables the above-mentioned effects. In addition, test work, which is performed separately in conventional systems, can be efficiently performed from the same terminal device D in one system.

Furthermore, it is possible to generate object code of higher quality than when using resident utility such as a minicomputer.

You can also banish paper media. Edit, compile, assemble, run (test)
By making job stream commands independent of the target machine, the programmer can be freed from the operation of the target machine.
