Discloses a program degrading check method for performing a degrading check.

Japanese Unexamined Patent Publication No. Hei 5-94298 discloses a degrade check execution device which can easily test whether or not existing functions are affected when a program module is changed.

Japanese Patent Application Laid-Open No. Sho 63-45641 discloses that a test program stored in a permanent file is run on an OS under development and an OS under development by using a virtual machine, and the two results are stored in a stable manner. There is disclosed a program degrading check method using a virtual computer, which improves the work efficiency by automatically performing a running result comparison program in a developed OS having a certain program.

[0005] The present invention relates to a method and apparatus for degrading an application program when input / output data is changed.

In general, a degrading check of a data update application program is performed by using output data output for input data when an unmodified application program is executed, and executing the modified application program after the modified application program is executed. This is performed by comparing output data output for the same input data.

[0007] Here, the data format of input data and output data may be different before and after the application program is corrected.

[0008]

In such a case, the input data (that is, the input data in the old data format) conventionally input when the application program before the correction is executed is replaced with the input data after the correction. A batch program tool or the like is created and used for input data in a data format that can be input when the application program is executed (that is, input data in a new data format). .

Similarly, in order to compare output data,
Output data output when the application program before the correction is executed (that is, output data in the old data format) is converted into data in the data format that is output when the application program after the correction is executed (that is, new data). A tool to convert the data into output data (data format) was required.

In the conventional degrade check, a portion for performing the above-described data conversion process, a portion for executing the modified application program, and an output result obtained by executing the modified application program are compared with the output result of the unmodified application program. Since the part to be compared with the output result of the execution is independent of each other, the execution procedure is complicated.

The above-mentioned conventional problems are summarized as follows.

That is, the first problem is that in the related art,
It takes time to convert the data format.

The reason is that the input data and the output data when the application program before the correction is executed (that is, the input data and the output data in the old data format) are converted into the input data when the application program after the correction is executed. And as a means for converting to a format of output data (ie, input data and output data in a new data format)
This is because a dedicated data conversion batch program or the like must be created each time.

Further, the second problem is that, in the prior art,
The procedure for performing the degrade check becomes complicated.

The reason is that the data conversion process, the corrected application program, and the corrected output of the application program are compared with the output of the unmodified application program. This is because each of the functions is independent as a separate function.

An object of the present invention is to provide input data and output data when an unmodified application program is executed (that is, input data and output data in the old data format).
Data format conversion that can convert data formats to input data and output data formats (ie, new data format input data and output data) when the application program after the correction is executed An object of the present invention is to provide a degrade check device having a function.

Another object of the present invention is to provide a data format conversion function for performing a data format conversion in a short time by having a data format difference layout file describing a difference between an old data format and a new data format. The present invention is to provide a degrade check device provided with:

Still another object of the present invention is to provide a degrading check apparatus which simplifies the procedure of degrading check which tends to be complicated and which can perform from data conversion to comparison result output by one operation.

Another object of the present invention is to execute an application program after correcting input data and output data (that is, input data and output data in the old data format) when the application program before correction is executed. It is an object of the present invention to provide a degrade check method capable of performing a conversion of a data format for converting to a format of input data and output data at that time (that is, input data and output data of a new data format) in a short time.

Still another object of the present invention is to provide a degrade check method in which data format conversion is performed in a short time by using a data format difference layout file that describes a difference between an old data format and a new data format. To provide.

Referring to FIG. 1, the degrade check device according to one embodiment of the present invention has a degrade check mechanism 3 including a correction program (an application program after correction) 32 to be degraded and a degrade check control unit 31. .

The degrade check control unit 31 inputs data (ie, old data format input data) that was input when the application program before correction was executed.
From the old data format input file 11, and
Output data (ie, output data in the old data format) output when the application program before the correction is executed is received from the old data format output file 12. Here, the combination of the old data format input file 11 storing the old data format input data and the old data format output file 12 storing the old data format output data is combined with the old data format input / output file 1. Called.

The degrade check control unit 31 inputs the old data format input data from the old data format input file 11 when the correction program (modified application program) 32 is executed.

The new output data of the new data format output to the new data format new output file 53 is stored in the new data format old output file 5.
2, compared with the old output data in the new data format,
The difference between the two is output as the comparison result 4.

The layout file 2 stores the difference between the layout of the input data in the old data format from the old data format input file 11 and the layout of the input data in the new data format to the new data format input file 51. This is a data format difference layout file that stores the difference between the layout of output data in the old data format from the data format output file 12 and the layout of old output data in the new data format to the new data format old output file 52. The degrade check control unit 31 refers to the layout file 2 and refers to the old data format input file 1

Referring to FIG. 2, old data format input file 11 updated by the application program before correction
It is assumed that the layout (C1) has been changed to the layout (C2) of the new data format input file 51 by modifying the application program. (The input and output data formats of the program to be degraded are assumed to be the same. That is, the old data format input / output file 1 has the same data format, and the new data format input / output file 5 has the same data format. It turns out that.)
Further, one input / output file is composed of a plurality of records,
It is assumed that each record has a unique value for identifying the record. Assuming that this is record No. I will call it.

As a layout file 2 in FIG. 1, a difference between the old data format C1 and the new data format C2 is described.
The layout file C3 shown in FIG.

In the layout file C3 of FIG.
The portions indicated by circled numbers 1, 6, 7, and 10 are descriptions of changes between the old data format C1 and the new data format C2 of the record.

For example, in the portion indicated by the encircled numeral 1, 01 is the record No. in each of the old data format C1 and the new data format C2. 16 indicates the number of bytes of the record of the old data format C1, and 11 indicates the number of bytes of the record of the new data format. Therefore, the portion indicated by the encircled numeral 1 indicates that the record length has become shorter.

Similarly, a portion indicated by a circled number 6 indicates deletion of a record, a portion indicated by a circled number 7 indicates an increase in record length, and a portion indicated by a circled number 10 indicates addition of a record.

The parts indicated by the other circled numbers 2 to 5, 8 and 9 are descriptions of changes between the old data format C1 and the new data format C2 of the items in the record.

For example, the portions indicated by the encircled numerals 2 to 5 are record Nos. The change of each item of record 01 is shown. For example, in the portion indicated by the encircled numeral 2, 4 at the left end is the number of old bytes, 4 at the center is the number of new bytes, and 1 at the right end.
Indicates that this is the first item in the record. Therefore, the portion indicated by the circled numeral 2 indicates that the item has not been changed between the old and new data formats.

Similarly, the portion indicated by the encircled numeral 3 indicates deletion of an item, and the portions indicated by the encircled numerals 4 and 5 indicate that the order of the items has been changed.

And the old data format output file 12 is converted into the new data format input file 51 and the new data format old output file 52, respectively (steps A3 and A4).

Referring to FIG. 4, data conversion is performed as follows.

One record is read from the data file to be converted (step B1), and it is determined whether the record is a record to be converted (step B3).

In the case of a record to be converted, a record having a new layout is created based on the conversion table (step B4).

This record is output to a file, and the process is repeated until there are no more records (steps B1 to B
5).

Returning to FIG. 3, the input / output data conversion (steps A3 and A4) includes the data conversion processing (step B).
1 to B5) are repeated until the old data format input / output file 1 is exhausted.

The new data format input file 51 thus converted is read as an input file (step A5).

The correction program 32 is executed based on the read data. As a result, a new data format new output file 53 is generated (step A7).

This processing is performed by using the new data format input file 51.
(Steps A5 to A7).

Next, the degrade check control 31 compares the old output file 52 with the new data format and the new output file 53 with the new data format. The result of this comparison is output as comparison result 4 (step A8).

The first effect of the above-described embodiment of the present invention is that the time required for the degrade check is reduced.

The reason is that by providing a data format difference layout file describing the difference between the old data format and the new data format, a special means for converting the input / output file from the data in the old data format to the new data format ( This is because there is no need to create a conversion program or the like, and data format conversion can be performed in a short time.

The second effect of the embodiment of the present invention is that the method of the degrade check is simplified.

The reason is that the operations from data conversion to result comparison can be performed by one operation.
