DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test route verification apparatus for verifying the validity of a program test after a program change, and more particularly, to extracting a part affected by the change in a program test after the program change. And a test route verification device for verifying whether or not a test of an affected portion has been performed.

2. Description of the Related Art For example, in the case of a system that is the backbone of a business established in a company, it is very difficult to replace the system with a new system when dealing with a new business environment. Many of them respond at any time by changing the program. Such a system is customizable according to the business specifications at the time of construction, or consists of a large number of programs,
In some cases, it is assumed that it will be used for a long time. However, in the long term, there are not only changes in the business environment but also replacement of developers involved in customization. Due to program changes and substitution of developers to cope with the business environment, it is difficult to grasp the flow of programs in the entire system, and it is difficult to judge the validity of the changed programs when testing them. ing.

Therefore, in order to extract only the steps related to the modified matter from a large number of steps and verify the program test, the conventional test route verification method searches the program information on the matter to be modified this time from the program before modification. A search result, a comparison result of comparing the pre-correction program with the post-correction program, and an execution route result indicating an execution route on the post-correction program executed by the program test were output. Based on the experience, the developer selects the affected steps and the unaffected steps from the search results, and executes the steps indicated by the execution route results according to the comparison result between the pre-corrected program and the modified program. The validity of the program test is determined by verifying whether the selected search result has been executed and verifying whether the selected search result has been executed (Japanese Patent Laid-Open No. 62-216047).

[0005]

However, the above-described conventional apparatus for verifying a test route has the following problems.

As a result, if the number of steps to be verified is large, even an experienced developer takes time to extract the affected steps from the search results, and also requires a program test based on the execution results. Judgment of validity required skill.

Further, for example, a program modification such as adding or deleting a branch code or a customer code is more likely to occur than other program modifications, and it is necessary to respond quickly. In this case, it is necessary to appropriately judge the validity of the test route executed for the program after the correction and to quickly evaluate the program after the correction. In such a situation, it is difficult for the successor developer or administrator to verify the validity of the program test.

Accordingly, a first object of the present invention is to provide a test route verifying apparatus for extracting an affected portion based on a change in a program test after a program change and verifying whether the affected portion has been tested. That is.

A second object of the present invention is to provide a storage medium storing a program for causing a computer to perform the processing in the above-described apparatus.

[0010]

Means for Solving the Problems In order to solve the above first problem, the present invention provides a semiconductor device comprising:
In a test route verification device for verifying the validity of an execution route that tests a modified program that has been modified according to a modification item, a pattern registration unit that registers a source code pattern to be searched from a program before modification; Pattern determining means for determining a source code pattern to be used for verifying the execution route in association with a correction item from the code pattern, and determining the source code pattern according to the pre-correction program position having the source code pattern determined by the pattern determining means. Verification means for verifying the validity of the execution route based on the corrected program position.

In such a test route verification device, the validity of the test route is verified based on the source code pattern determined according to the correction item.

Therefore, since the user can verify the test route only by inputting and confirming the source code pattern, no special program knowledge for verification is required.

The above source code pattern is' MOV
A command word such as E 'or' IF ', or a name corresponding to the command word which is easy for the user to understand, for example, information such as'transfer' corresponding to 'MOVE' and 'comparison' corresponding to 'IF',
And a pattern number uniquely set to the information.

The above-mentioned correction item is an item to be corrected by the program. For example, when the "branch code" in the program is corrected to add a branch code, it is indicated by a "branch code".

From the viewpoint that the validity of the execution route can be verified, the present invention provides a test route verification apparatus according to the first aspect, wherein the pattern determination means includes the pattern registration means. A pattern type setting means for setting a type of a suppression pattern for suppressing the verification in the execution route or a type of an emphasis pattern for emphasizing the verification in the execution route. The validity of the execution route can be verified based on the corrected program position corresponding to the pre-correction program position having the emphasis pattern determined by the means.

In such a test route verification apparatus, a pattern type indicating “inhibited” or “emphasized” can be specified from among the registered source code patterns, and the source code pattern to be verified can be determined.

Therefore, the verification of the execution route can be skipped for the inhibition pattern, and the validity can be determined only for the emphasis pattern. The execution route to be verified can be narrowed down by this type.

Alternatively, in order to solve the first problem,
According to a third aspect of the present invention, there is provided a test route verification apparatus that verifies the validity of an execution route that tests a modified program that has been modified according to a modification item.

Route determining means for determining whether the corrected location information has been tested by searching. In accordance with the determination result by the determination unit, configured to have an output means for outputting the judgment result.

Such a test route verification device can narrow down the execution route to be verified based on the pre-correction program position affected by the correction item.
Further, based on the output determination result, the user can review the test or parameter items or review the program based on the output corrected position information.

From the viewpoint that the validity of the execution route can be verified, according to the present invention, the correction information table has change information indicating whether or not there is a change in the correction position information, The influence information table has emphasis information indicating the presence or absence of emphasis in the verification of the execution route, and the route determination means matches the emphasis information indicating that emphasis is present with the set influence position information, and has a change. When the pre-correction position information in which the change information indicating the setting is set is present in the correction information table, the execution route information stored in the execution route table is searched based on the post-correction position information corresponding to the pre-correction position information. Thus, it can be configured to determine whether the corrected position information has been tested.

Such a test route verification device can further narrow down the execution route to be verified by using the emphasis information indicating that emphasis has been performed and the change information indicating that change has been performed.

Therefore, it is possible to verify the execution route according to the more appropriate modification item.

The change information is set to, for example, “U” when changed and “D” when deleted in the corrected program.

In order to solve the second problem,
According to a fifth aspect of the present invention, there is provided a program for causing a computer to perform a process in a test route verification device that verifies the validity of an execution route that tests a modified program that has been modified according to a modification item.

In FIG. 4C, the search pattern instruction information table 130 has the same table configuration as the search instruction table 120, and sets a search pattern required for verifying a test route.

In the "item name" field, for example, when a branch code is added, data such as "branch code" is set.

The case automatic identification process executed by the CPU 11 of FIG. 1 will be described with reference to FIGS.

FIG. 5 is a flowchart showing the automatic case identification processing, and FIG. 6 is a diagram showing an example of the automatic case identification processing.

For example, a case where a user adds a branch code will be described.

In FIG. 6, the user operates the display unit 1
Keyword 1 of the matter information input screen 140 displayed in 5
When an item considered to be affected by the addition of the branch code, for example, a branch code is input to 42 and the search 150 is clicked, the automatic case identification process is started.

As shown in FIG. 5, the CPU 11 searches the case pattern table for a keyword based on the keyword input from the case information input screen 140, and expands the corresponding data in the memory unit 12 (step S171).

The CPU 11 searches the case pattern table 110 stored for each case to determine whether a plurality of cases have been searched (step S172). If a plurality of cases are found, a case list screen is displayed and the user is allowed to select a target case (step S173). If a plurality of cases has not been found, or if the user has selected a desired case from the plurality of cases, the CPU 11 executes step S174.

In step S174, the case summary 143 of the target case, the search suppression pattern 1
44 and the search emphasis pattern 145 are displayed in the case information input screen 140. With this display, the user can
By clicking each edit of the suppression pattern and the emphasis pattern, the edit becomes possible.

The CPU 11 determines the button clicked by the user (step S175). If the cancel button 148 is clicked, the input by the user is invalidated, and the process returns to the beginning. S176 is executed, and if editing of the emphasis pattern 145 is clicked, step S177 is executed. If editing of the suppression pattern 144 is clicked, step S177 is executed.
179 is executed, and when the case pattern registration 146 is clicked, the step S181 is executed.

In step S176, the CPU 11
Outputs the information of the search suppression pattern 144 and the search emphasis pattern 145 input to the case information input screen 140 to the search pattern instruction information table 130.

This search pattern instruction information table 130
, An influence search process described later is executed.

In step S177, the CPU 11
Displays on the display unit 15 information of the instruction type set in the emphasized pattern of the read search pattern instruction table. At this time, the instruction type which has already been emphasized, that is, displayed in the search result in step S172, is displayed with "emphasis" set. Further, the CPU 11
Reflects the information in the emphasis pattern 145 of the case information input screen 140 (step S178).

For example, if the user is supposed to add a branch code to particularly affect the constants among the comparison instructions in the program before correction, the emphasis pattern 14
Edit the information reflected in No. 5 and change it to “Comparison command: Constant”.

On the other hand, after the processing in step S178, the CPU 1
In step 1, the process returns to step S174 to determine the next click by the user.

In step S179, the CPU 11
Displays on the display unit 15 information of the instruction type set in the inhibition pattern of the read search pattern instruction table. At this time, the instruction type that has already been set to be inhibited, that is, the instruction type displayed in the search result in step S172, is displayed with “inhibited” set. Further, the CPU 11
Reflects the information in the suppression pattern 145 of the case information input screen 140 (step S178).

For example, if the user considers that the addition of the branch code does not cause the “CALL instruction” to have any particular effect on the program before modification, the suppression pattern 14
Edit the information reflected in No. 4 and change it to “CALL instruction”.

On the other hand, after the processing in step S179, the CPU 1
In step 1, the process returns to step S180 to determine the next click by the user.

In step S181, the CPU 11
When the "inhibition pattern" or "emphasis pattern" is edited (changed) by the user, it is newly registered in the case pattern table based on the newly set case name 141. In this case, the contents of the case pattern table 110 of FIG.
The information on the “emphasis” command type and the “inhibit” command type registered in the “1.

On the other hand, the CPU 11 returns to the step S174 to determine the next click of the user.

The user can set the command type of the program to be searched efficiently by the above-described automatic case identification processing.

Next, the influence search process will be described with reference to FIGS.

FIG. 7 is a diagram showing an example of a table used in the influence search processing.

FIG. 7A is a diagram showing a configuration example of the search information table 210, and FIG. 7B is a diagram showing a configuration example of the influence search route table 220.

FIG. 7A shows that the search information table 210
Is the “item name” field that indicates the data content, the “line number” field that indicates the line number of the program source before correction, the “branch line number” field that indicates the branch destination from the line number, and the program of the line number. An "instruction type" field indicating the type of instruction, a "source item" field indicating the left side of the instruction, a "transfer destination item" field indicating the right side of the instruction, and the type of the item in the instruction, that is, a search pattern instruction table And a “Pattern No.” field indicated by the unique number set in the above. The search information table 210 is a table in which instruction information is stored according to the execution route of the program before correction.

As shown in FIG. 7B, the influence search route table 220 includes an “item name” field indicating data contents,
An "emphasis mark" field to indicate that it is an emphasis line;
It is composed of a “line number” field indicating the affected line number and an “instruction line” field for describing an instruction code. The influence search route table 220 generated by the influence search process is referred to in an execution route matching process described later.

FIG. 8 is a diagram showing a flowchart of the influence search process.

The effect search processing executed by the CPU 11 of FIG. 1 will be described with reference to FIGS. 8 and 10.

As shown in FIG. 8, the CPU 11 determines in step S of FIG.
After the processing of 176, the search pattern instruction information table 130
Is read and expanded in the memory unit 12 (step S
241). For example, the search pattern instruction information table 130 shown in FIG. 9 is read.

For example, a search start line for searching for a program location affected by the addition of a branch code is set (step S242). A plurality of search start lines can be set. The search information file 210 is generated according to the set starting point.

For example, when the search start line set in the case of the unmodified program source as shown in FIG.
If it is 00 ′, the CPU 11 determines the line number 5000 as shown in FIG.
Is obtained as the search information file 210.

The CPU 11 determines whether all starting points have been searched (step S243). If the search has been completed at all the starting points, an execution route comparison process is performed. If not all, the process proceeds to step S244. In this case, the starting point is the search pattern instruction information table 130.
3 shows the position of each record in the search information table 210 including the data indicated by “item name”.

At the step S244, the CPU 11
Is “inhibited” in “instruction type” and “pattern number” of the line number (record) specified at the starting point of the search information table 210 and “type” of the search pattern instruction information table 130.
Are compared with the “instruction type” and the “pattern No.” When both the “instruction type” and the “pattern NO” match, the process proceeds to the next starting point set in step S242, and steps S243 to S245 are repeated. If they do not match, the process proceeds to step S246.

In step S246, CPU 11
Are the “instruction type” and “pattern N” of the line number being processed.
O ”and“ type ”of the search pattern instruction information table 130
Are compared with the “instruction type” and the “pattern No.” in which “emphasis” is set. "Instruction type" and "Pattern NO"
If both match, the necessary information from the search information table 210 is set in the influence search route table 220, and an emphasis mark is set in the "emphasis mark" field (step S248).

The CPU 11 extracts the source code of the source before correction that matches the “line number” of the search information table 210 matched in step S 248 from the asset before correction 72 shown in FIG. (Step S249).

By this step S249, the positions of the source before correction affected by the correction are listed.

The CPU 11 performs steps S250 to S254 to obtain the next processing line.

The CPU 11 determines whether the currently processed item in the search information table 210 is a branch instruction.
"Branch line number" is read (step S250), and it is determined whether a value (branch destination line number) exists in "branch line number" (step S251).

If the "branch number" exists, it is positioned at the "line number" that matches the "branch number" (step S2).
52). Subsequently, step S255 is processed.

On the other hand, if the "branch number" does not exist, the next line of the search information table 210 is read (step S2).
53). When the next line is read, the search information table 21
If 0 has been completed, the next starting point set in step S242 is read, and the same processing as described above is repeated from the row position of the search information table 210 specified by the starting point.

If not completed, it is determined whether the "transfer destination item" corresponding to the line number being processed matches the "transfer source item" corresponding to the read next line number (step S).
256). If they match, the process returns to step S244,
By repeating the same processing, it is determined whether the pattern is a suppression pattern or an emphasis pattern.

If they do not match, the flow returns to step S250 to read the next processing line.

In the example shown in FIG. 9, the data contents of the "item name" and the data contents of the search information table 210 are skipped by the respective judgment processes in the example shown in FIG. The determination result that the "item name" data content includes the "branch line number" of the data content (step S25)
1) and the determination result that the “transfer destination item” of the data content matches the “transfer source item” of the data content (step S2)
According to 56), the determination of the suppression or emphasis pattern is executed. Determination result that is not a suppression pattern (step S245)
And the judgment result of the emphasis pattern (step S248)
As a result, the information of the data contents of the search information table 210 is stored in the influence search route table 220, and the “instruction line” is obtained from the “IF branch code <
20 'is set.

Further, after the effect search processing on the data contents of the search information table 210 is performed, the table ends (step S254), and the execution route collation processing is executed when the start point ends (step S243).

When there are a plurality of starting points, an influence search route table 220 is created for each starting point.

Next, the execution route collation processing will be described with reference to FIG.
14 to FIG.

In the execution route collation processing, the influence search route table 220 generated in the influence search processing, the before and after line number comparison information 73 comparing the before-correction asset 72 and the after-correction asset 71, and the after-correction by test execution The program is executed with reference to the execution route information 91 of the program.

FIG. 11 is a diagram showing an example of a table used in the execution route collation processing.

FIG. 11A shows an example of the execution route information 91, and FIG. 11B shows an example of the correction information line number comparison information 73.

FIG. 11A shows that the execution route information 91
Is composed of an "item name" field indicating data contents, a "line number" field indicating a line number to be processed of the corrected program source, and an "instruction line" field indicating the corrected source code.

As shown in FIG. 11B, the modification information line number comparison information 73 includes an “item name” field indicating data contents,
It is composed of an “update flag” field indicating a correction category, a “line number before correction” indicating a line number of a source before correction, and a “line number after correction” indicating a line number of a source after correction. In the correction category, for example, “U” is set if the target row has been updated, and “D” is set if the target row has been deleted. The execution route comparison processing executed by the CPU 11 will be described with reference to FIGS.

FIG. 12 is a diagram showing a flowchart of the execution route collation processing.

Referring to FIG. 12, the CPU 11 sets an influence search route from the starting point to be verified (step S331).
An execution route corresponding to the set starting point is set (step S332). The influence search route from the starting point to be verified is
Multiple settings are possible.

The CPU 11 reads the influence search route table 220 corresponding to the starting point set in step S331 (step S333), determines whether or not reading has already been completed (step S334). The execution route matching processing ends. That is, the test route verification processing ends.

On the other hand, if the result of determination in step S334 is that the record is continued, a search is made to determine whether there is a record with an emphasis mark set in the read influence search route table 220 (step S335). If there is no record with the emphasis mark set, the process returns to step S333,
The influence search route table 220 corresponding to the next starting point is read, and the determination in step S334 is similarly performed.

On the other hand, if the result of determination in step S335 is that there is a record with an emphasis mark set, processing in step S336 is executed.

In step S336, the CPU 11
Reads the correction information line number comparison information 73 and positions it at the record that matches the line number (line number of the source before correction) of the record to which the emphasis mark is set.

The CPU 11 further reads the type of the "update flag" of the record positioned in the correction information line number comparison information 73 (step S337), and indicates "D" indicating deletion.
Is set, the process returns to step S333, and the same processing is repeated thereafter. If "U" indicating the change is set, the record of the execution route information 91 corresponding to the corrected line number of the record is set. Is retrieved (S338).

It is determined whether or not there is a row corresponding to the execution route information 91 (a record having the same row number after correction) (step S339), and if there is, the procedure returns to step S333 and an influence search route corresponding to the next starting point is determined. The table 220 is read and the same processing is executed.

On the other hand, if it is determined in step S339 that the corresponding row (record) does not exist, the corrected row number of the source is output to the output unit 13 in FIG. 1 as "test execution omission".

For example, from the corrected program source as shown in FIG. 14, the line number 5200 is changed to “IF branch code <
FIG. 13 shows an example of the execution route collation processing when “30”, that is, the comparison constant is changed from 20 before modification to 30.

In FIG. 13, the influence search route table 220 read in step S333 is
335 determines that there is an emphasis mark.

In the correction information line number comparison information 73, the "update flag" is determined to be "U" in the determination process S337, and the record of the execution route information 91 is searched based on the corrected line number (step S337). S338). in this case,
Since there is no line number in the execution route information 91 that matches the line number after correction of the correction information line number comparison information 73 (step S339), the output unit 13 outputs the execution route comparison result 310 as shown in FIG. Is done.

As described above, by specifying the suppression pattern and the emphasis pattern for the instruction code on the program source, only the instruction code specified by the emphasis pattern is extracted from the instruction codes affecting the modification of the program source. It is possible to do. Therefore, in the execution of the program test, it is possible to verify the validity of the execution route by determining whether the instruction code specified in the emphasis pattern is included in the executed route. That is, the validity of the test route executed for the corrected program can be appropriately determined, and the corrected program can be quickly evaluated.

Further, the user can verify the validity of the execution route only by setting the inhibition pattern and the emphasis pattern from the case information input screen displayed on the display unit 15. Therefore, it is not necessary to verify the suppression pattern and the emphasis pattern while reading the source code, and
Does not require specialized program knowledge or knowledge of the program content being tested.

In the above example, the processing in the case where the branch code is added is shown, but the processing is not limited to the branch code.

In the above example, the processing in step S181 shown in FIG. 5 corresponds to the pattern registration means of claim 1, and the processing in step S176 shown in FIG.
Corresponds to the pattern determination means.

The processing in steps S333 to S338 shown in FIG. 12 corresponds to the route determining means in claim 3, and the processing in steps SS339 to S340 in FIG. 12 corresponds to the output means in claim 12.

[0120]

As described above, according to the present invention as set forth in claims 1 and 2, "deterrence" or "emphasis" is performed.
The verification of the execution route can be skipped for the inhibition pattern based on the source code pattern corresponding to the correction item in which the pattern type indicating is set, and the validity of only the emphasis pattern can be verified. That is, the execution route to be verified can be narrowed down by this type.

Therefore, the user can verify the test route only by determining the source code pattern, and does not need any special program knowledge for verification.

According to the third and fourth aspects of the present invention, an execution route to be verified can be narrowed down based on a pre-correction program position affected by a correction item. Further, the execution route to be verified can be further narrowed by the emphasis information indicating the emphasis is present and the change information indicating the change is present. In addition, the user,
Based on the output judgment result, the test or parameter items can be reviewed, or the program can be reviewed based on the output corrected position information.

According to the fifth or sixth aspect of the present invention, it is possible to provide a storage medium storing a program for causing a computer to perform the above-described processing in the test route verification device.
