Description

  The present invention relates to a method and a program for performing an impact analysis accompanying a program change.

  A tool based on the result of a static analysis is usually used in the impact analysis for examining the impact range of a modification when a certain module is modified. However, in the influence analysis based on the result of the static analysis, the extracted influence range is often enormous, and the man-hour for verifying whether there is a real influence becomes large.

  As a technology that prevents the amount of man-hours for verification from becoming enormous due to the extraction of such an influence range, a module affected by the change is identified by detecting a change in the precondition, and the result of the static analysis is used. A method is known in which only the influence range based on the identified module can be narrowed down and extracted, thereby solving the problem of increasing the number of steps for verifying the conventional influence range (for example, see Patent Document 1).

JP 2008-191963 A

  In the technique disclosed in Patent Document 1, a module that is directly affected by a change is identified, and only the identified module and the module that calls the identified module are used as the base points, and related results are obtained from the results obtained by static analysis. By setting a certain module as the influence range, it is possible to suppress an increase in the number of steps for verifying the presence or absence of the conventional influence. However, when there are a large number of modules having a direct call relationship from the base module, the range extracted as the influence range becomes large, and the verification man-hour may be increased. In addition, even when the extracted influence range is small, it is necessary to verify an effective path that does not actually need correction.

  It is an object of the present invention to provide a technique that can extract only the execution paths that have an influence and extract the influence range more narrowly than in the past, and reduce the number of verification work steps.

  One means for solving the above problem will be described. That is, the present invention is an influence analysis method in an influence analysis apparatus that analyzes an influence accompanying a change of a module (program). The impact analysis apparatus includes an input unit, a storage unit, a control unit, and a display unit, and the storage unit has a module name, a combination test result that is a result of a combination test of the plurality of modules, and the The execution order of the modules at the time of the combination test, the unit test result that is the result of testing the changed module alone among the plurality of modules, the module names of the modules that are executed in combination, and the execution order of these modules And a check list number that uniquely identifies a combination of the module names of the modules to be executed in combination and the execution order of these modules are stored in association with each other. Then, the control unit acquires the module name of the change module via the input unit, searches the storage unit based on the acquired module name, and the combination test result and the unit test of the module of the corresponding record. The result is collated, and when the result of the collation is that both the results do not match, the storage unit stores the execution order in which the checklist number of the corresponding record is the same and is larger than the execution order of the corresponding record The identified record is identified, the module name is extracted from the identified record, and the extracted module name is displayed on the display unit as the module name of the module that is affected by the module change.

  According to the present invention, the influence range at the time of module correction can be extracted in a narrower form than before, and the man-hours for verification can be further reduced.

The unit test execution function 112 acquires the module name (in this example, module A) input by the user on the unit test execution function screen 1000 using the input unit 103 (step S403), and uses the acquired module name as a key. The module name 204 of the impact analysis table 114 is searched for (in this example, module A), checklist number 202 (in this example, CCL001, CCL002, CCL003) and input information 205 (this time). In this example, the unit test output information 207 (with no value in this example) is extracted (step S404), and the module name obtained in step S403 (in this example, module A and Checklist number 2 extracted from the impact analysis table 114 2 (CCL001, CCL002, and CCL003 in this example) and input information 205 (1, 10, and 200 in this example) are displayed on the unit test execution function screen 1000 shown in FIG. 10 as unit test input conditions. (Step S405). Next, when the user performs an operation of pressing the execution button 1006 on the unit test execution function screen 1000 using the input unit 103, the unit test execution function 112 among the modules in the module storage area 116 performs unit test execution. For the module with the module name acquired from the function screen 1000, a unit test is executed with the input information 205 (1 in this example) extracted from the impact analysis table 114 as an input, and output information (2 in this example). (Step S406), and the acquired output information is stored (including updated) in the unit test output information 207 of the record of the impact analysis table 114 that matches the check list number 1003, the module name 1004, and the input information 1005. (Step S407).

  Next, the unit test execution function 112 determines whether or not the unit test has been performed on all of the acquired input information (step S408), and if not, returns to the process of step S406. Exit.

The module name (referred to as module A in this example) input to the influence range analysis function screen 1100 by the user using the input unit 103 is acquired (step S503), and the influence range extraction process is executed (step S504). ).

  FIG. 6 is a flowchart showing the influence range extraction process performed by the influence range analysis function 113 included in the influence analysis apparatus 1.

  The influence range extraction process S504 searches the module name 204 in the influence analysis table 114 using the module name acquired in S503 as a key (in this example, module A), and acquires information of the corresponding record (step S601). Next, in order to examine the change of the output information for the same input information before and after the modification of the module and to extract the execution path that is affected, the output information 206 of the acquired record (in this example, 2) and the unit test The output information 207 (2 in this example) is collated (step S602).

  Next, the influence range extraction process S504 determines the result of the match (step S603), and when the match matches, executes the process of step S606. On the other hand, if the matches do not match, the check list number 202 (in this example, CCL002 and CCL003) of the matched records is the same from the impact analysis table 114, and the execution order 203 of the corresponding records searched in step S601 ( A record storing a larger execution order is specified (in this example, 1 and 2), and a module name 204 (in this example, module D, module E, and module G) is extracted from the specified record ( Step S604). A record having a large execution order is identified by modules (module B, module C, and module in this example) that are executed after the matched module (module A in this example) as shown in FIG. This is because the output information of the matched module (in this example, module A) is used as input information, and it is necessary to verify whether it is affected. The extracted module name is held as an impact analysis result list (step S605).

  Next, in the influence range extraction processing step S504, it is determined whether or not the output information 206 and the unit test output information 207 have been matched with respect to all the acquired records (step S606), and if not, the process returns to the process of step S602. . On the other hand, when the output information 206 and the unit test output information 207 are matched with respect to all the acquired records, the held influence analysis result list is displayed on the influence range analysis function screen 1100 shown in FIG. 11 (step S607).
