Description

Test Method and System for System Maintenance Based on Efficiently Improved Test-case Reuse}

The present invention relates to a test performing method and system for system maintenance and repair, and more particularly, to the efficiency of development of a system for effectively maintaining and maintaining customer relationship information, such as a customer relationship management (CRM) system. As the importance of test case reuse is increasing, it is possible to write test cases appropriately for the purpose of functions and user requirements, and to manage them to be utilized wherever needed. It relates to a method and a system for performing tests for system maintenance.

Due to the nature of the system maintenance development project, most of the changes are made to existing functions rather than new functions. For example, a CRM system for maintenance is an example. In a wireless network business that supports wireless calls, wireless Internet, and wireless data download / upload services through base stations, financial information (product sales, sales, operating profit, etc.) and customer related information (customer satisfaction) for system maintenance , The number of subscribers, the number of users, etc.), and the internal management information (accounts receivable, collection of bills, etc.) can be managed to identify the customer relationship information. The necessary functions can be further developed or changed so that customer relationship information can be effectively managed.In this case, test cases for the implemented functions must exist and be managed. The test should be performed.

Projects related to maintenance systems have a number of problems associated with testing. First, we can talk about the problem of test scenario creation criteria. Currently, test scenarios are being created / managed, and the reuse rate is not low. However, since screen scenarios are created, it is difficult to identify functions to focus on actual test execution. As a result, there is a risk that test execution will be formalized independently of the function, and it is difficult to increase the efficiency of the entire system by finding a function that needs improvement.

In addition, since the test scenario creation level is different for each developer, it is difficult to perform the same quality test for each required function. This can reduce the likelihood that the same test will be performed according to the correct procedure if the developer changes, or if someone else tests, because the test is performed by the developer rather than the function.

Finally, there is a problem in that the test scenario for the defective function is not corrected after development. If the actual failure does not apply to a test scenario, a change in the functionality in the future increases the likelihood that the same defect will occur in the past. And if you change other functions, the impact analysis may not be done properly, which may cause unexpected defects.

Therefore, to solve these problems, there is a need for a method and system that can introduce test case concepts, improve test scenario creation procedures, and apply them to automate the reuse of test cases.

Accordingly, an object of the present invention is to solve the above-described problem, and an object of the present invention is to provide a maintenance / maintenance system in which a change of an existing function occupies most of a requirement, rather than adding a new function due to the nature of system maintenance. As test case reuse is becoming more important for development efficiency, test cases can be effectively managed by allowing them to be written for the purpose of function and user requirements, and managed wherever needed. The present invention provides a reusable test method and system for system maintenance.

In addition, the unit test cases, business functions, and functions of the unit test to establish test cases for each test purpose, such as unit tests to ensure the integrity of the function, and integrated tests to confirm that they are implemented for the purpose of the user requirements. Improving the system to create integrated test cases for requirements, and managing the test cases through the system to perform tests for system maintenance, enabling the same level of testing of functions and tasks whenever necessary. It is to provide a method and system.

In addition, through various test cases and test procedures, it is possible to efficiently manage problematic functions, prevent recurrence of the same defects, and perform integrated tests by analyzing the effects with other functions. To improve test quality, reduce development errors, and ultimately reduce test case development efforts and increase development efficiency, enabling effective development management and improving quality The present invention provides a method and system for performing tests.

It also identifies the required functions on the development or test side, allowing you to create and manage unit test cases for unit testing for those unit functions, and integrate test cases for all business functions required to meet the requirements. Allows you to automatically create individual test cases based on unit test cases and manually add individual test cases needed to perform test specific to your requirements, and the newly added test cases are automatically applied to the unit test case master of the function as needed. The present invention provides a method and system for performing tests for system maintenance.

In addition, by analyzing the analysis of defects / failures in each test case after test execution or system operation, the basis for preventing future occurrence of the same error in advance is provided, and the weak part that needs improvement through functional analysis. To reduce the time and effort required to write test cases, it is possible to provide a method and system for performing tests for system maintenance that can improve overall development efficiency and enable effective development management.

First, to summarize the features of the present invention, the test method for system maintenance and repair according to an aspect of the present invention for achieving the above object of the present invention, generates a test case for the function reflecting the requirements of the user Making; Storing the generated test case in a database; And providing the test case for testing whether a function of the test case satisfies a corresponding requirement.

In addition, a test system according to another aspect of the present invention, a user interface for processing input and output of information for system maintenance and repair; A test case generation unit generating a test case for a function reflecting a user's requirement; A database for storing the generated test cases; And a controller for providing the test case through the user interface in response to a request.

According to the test performing method and system for system maintenance according to the present invention, it is possible to improve the quality of the unit test procedure and content by creating all possible test cases for the unit function at the same level on the development side or the test side. In addition, this increases the effectiveness of the test and enables detailed test execution.

In addition, according to the test performing method and system for the system maintenance according to the present invention, because the characteristics of the system maintenance / maintenance is a change of existing functions rather than new additional functions, once defined test cases can be reused continuously in the future By dramatically reducing test scenario creation time, the overall development efficiency can be increased.

In addition, according to the test performing method and system for system maintenance / maintenance according to the present invention, it is possible to reduce the same development error that occurred in the past by managing and reusing a predefined test case.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited to the embodiments. Like reference numerals in the drawings denote like elements.

1 is a view for explaining a development procedure of a project for system maintenance / maintenance applying the test method according to an embodiment of the present invention.

Referring to FIG. 1, various functions are developed to operate a system for effectively maintaining and maintaining customer relationship information, such as a customer relationship management (CRM) system for maintenance. This function should be managed to be made, these functions should be operating (130) without defects or failures after the development (110) and test (120) is made.

For example, in a wireless network business that supports wireless calls, wireless internet, and wireless data download / upload services through base stations, financial information (product sales, sales, operating profit, etc.) The functions can be managed to identify customer relationship information such as information (customer satisfaction, number of subscribers, number of users, etc.) and internal processing information (receivables, collection of utility bills, etc.). Here, for the system maintenance / exemplification functions for allowing the operator or user to easily access and use the above customer relationship information, but not limited to this, the functions developed in the project in this specification are wireless network operation In addition to CRM, a comprehensive set of functions appears on all projects related to system maintenance and all related development plans.

In the present invention, necessary functions can be additionally developed or changed so that the above-described customer relationship information can be effectively managed, and the test case for the implemented function is managed, and the past test case even when the corresponding function is changed. In order to ensure that the same level of testing can be performed, we propose a method of performing tests in system maintenance and a system implementing the same. In addition, because of the nature of system maintenance, it is important to reuse test cases for the efficiency of development of maintenance systems where changes in existing functions take up most of the requirements, rather than adding new functions. And the test case can be effectively reused by making it suitable for the purpose of user requirements and managing it to be used regardless of the place when needed.

To this end, in FIG. 1, in the development stage 110, a developer or a development performance management side collects and analyzes user requirements, identifies necessary functions, and prepares or changes necessary test cases (111). Analyze and design (112) develop the unit function (113). In the test phase 120, the operator or the test performance management side reflects user requirements in the unit test execution 121, analysis and design phase 112 for the unit function developed in the development step 113 as described above. Perform an integration test 121, and a user test 123 at a user requirement level.

In the present invention, in the development step 110 generates a unit test case for the function developed by reflecting the requirements of the user (115) and generates an integrated test case (116) immediately a predetermined application for system maintenance Once a test case baseline has been established (117) by deleting, modifying, or adding to (e.g., software, hardware, or a combination thereof), the test step 120 uses it to apply that functionality to the requirements. Effectively test whether or not The unit test case is a test case for checking whether a developed unit function is in error, and the integrated test case is a test case for checking whether an operation function is in error for a user's requirement.

In the test execution 120, the unit test is performed through the unit test execution 121, the integration test execution 121, and the user test 123 using the unit and the integrated test case established after the completion of development. .

After the test run 120, the result or failure of a function (e.g., an incomplete error of the function itself) or a failure (e.g., an imperfection in functioning by other obstacles) on the system 130 If an error related to the error occurs (131), the errors are collected and analyzed (132) to be reflected in the generation of unit and integrated test cases and supplemented, so that the test case can be used for future reuse. can do.

Accordingly, after the test 120 or at the time of system operation 130, the analysis content of the defect / failure of the function can be reflected in the test case for each function, and the basis for preventing the same error from occurring in the future. It can be prepared and used to identify weak areas that need improvement through functional analysis. In addition, this greatly reduces the time and effort required to create test cases, enabling overall development efficiency and effective development management.

System administrators or function developers can search, delete, or change the unit / integrated test case that has already been created through the database of the application in which the unit / integrated test case is managed for reuse in the test at any time. As a result, new unit / integrated test cases can be generated and updated in the database according to the function and user's requirements.

As a result, it is possible to efficiently manage problematic functions, prevent recurrence of the same defects, and analyze and reflect the effects of other functions through integrated tests. In addition, it is possible to improve test quality through various test cases and test procedures, and to reduce the occurrence of development errors, thereby reducing test case development effort and increasing development efficiency, thereby enabling effective development management and improving quality. It can be improved.

As shown in Figure 2, in the analysis and design step 112, the integrated test case for checking the error of the business function for the user's requirements is a variety of business functions (for example, unique function 1, unique function 2, .., A function 1 associated with a unit function, a function 2 associated with a unit function, ...) may be written to allow a test procedure to be established. Here, at least one test case may be generated based on the unit test case as an integrated test case for a function associated with the unit function. As an integrated test case for a unique function, at least one test case unique to the corresponding business function may be generated independently of the unit test case. When the function identified in the user requirement collection step 111 is changed, added, or deleted, it can be updated to reflect the integrated test case of the requirements accordingly.

For example, as shown in FIG. 3, the integrated test case for the business function of 'representative distributor monthly statistics' includes 'individual distributor monthly performance information query', 'representative representative monthly performance information query', and 'installation opening blocking processing'. Test cases may be included. This is merely illustrative and may include a variety of more test cases for other functions of the system for many other maintenance operations involving different customer relationship information.

In FIG. 2, a unit test case for checking an error of a unit function developed in the development stage 113 is included in a corresponding unit function (for example, unit test case 1, unit test case 2, .. unit test case n). Can be written to ensure that test procedures are established. As a unit test case, at least one test case for a corresponding unit function may be included. The purpose of writing unit test cases is to ensure that the functionality developed is flawlessly complete. In addition, when the function identified in the analysis and design step 112 is changed during the development, the information about the function may be reflected in the unit test case and the integrated test case.

For example, as shown in FIG. 4, the 'individual agency monthly performance information query', which is one of the integrated test cases as described above, checks whether the phrase 'new subscription case' is changed to 'three month average new subscription case'. Unit test cases such as Here, the function of the software such that the information previously displayed as 'new subscription' on the user's predetermined terminal screen in the maintenance / maintenance system is displayed as '3 month average new subscription' according to the user's requirements during the test or operation. In the case of the development, in order to confirm whether the test or operation is reflected on the terminal as such, "Check whether the" new sign-up "phrase has been changed to" 3 month average new sign-up. " This means that the same test case should be managed and maintained. Similarly, various unit test cases as shown in FIG. 4 may be included in each of the representative representative monthly performance information inquiry and the installment opening blocking process. Whether or not the function is fully operated according to each unit test case may be determined to be consistent with the expected result of pre-determined management while testing or operating the function. For example, in FIG. 4, it is expected whether the corresponding inquiry condition input screen appears when the corresponding function is fully operated with respect to the unit test case "Clicking the 'search' button", and the screen is actually displayed on the user screen. If this appears, the developed function is complete without defects. Such unit test cases are also illustrative only and may include a variety of more test cases for other functions of the system for many other maintenance operations involving different customer relationship information. The expected result of each unit test is determined by the data input / change completion status and the condition input / change completion status according to the unit test, and its function is defective depending on whether the test results are consistent with the expected results. Or it can be determined whether it is being performed properly without any obstacles.

As noted above, features developed for systems that effectively maintain and maintain customer relationship information, such as CRM systems, need to be tested before they operate, reflecting user requirements in the analysis and design phase 112. Comprised of a number of business functions that are presented roughly, each business function consists of a number of specific unit functions developed in the development stage (113).

In order to test the integrity of these functions, integrated test cases as described above may be databased for each business function, and unit test cases as described above may be databased for each unit function. As a result, integrated test cases consisting of unit test cases may be generated for testing of each business function, but for the test of each business function, an integrated test unique to the corresponding business function is independently performed regardless of the unit test case. Cases may also be included.

Such unit or integrated test cases are utilized in the test execution 120. In the development side or the test side, in the unit test execution 121, analysis and design phase 112 for the unit function developed in the development step 113 Comprehensive and multifaceted testing may be performed through the integrated test 122 for the business function reflecting the user requirements, and the user test 123 of the user requirement level. In the integrated test execution 122, the integrated test cases as shown in FIG. 3 established for the corresponding business function may be used to test whether the user requirement is properly reflected in the business function composed of the unit functions. In addition, in the unit test execution 121, the unit test cases as shown in FIG. 4 established for the unit function are utilized to test whether the developed unit function is complete. In addition, in the user test 123, the above integrated or unit test cases established for the business function or the unit function related to the requirements can be used to test whether the user requirements are properly implemented. Each of the above tests can be done in any order, and for each level, whether development, test, or user uses unit or integrated test cases to reflect user requirements and appropriate implementation functions. You can test from multiple angles.

Accordingly, the present invention provides a unit test case for a function for establishing a test case for each test purpose, such as a unit test to ensure the integrity of the function and an integrated test to confirm that it is implemented appropriately for the purpose of the user requirements. Integrated test cases for business functions and requirements were made possible, and managed through the database of the system where the application was installed so that they could be reused whenever necessary to perform the same level of test on the functions and tasks. Identify required features on the development or test side to create and manage unit test cases for unit testing for those unit functions, and unit test integrated test cases for all business functions required to meet requirements You can also manually add individual test cases that are automatically generated based on the case and perform test specific to the requirements, and the newly added test cases can be automatically applied to the unit test case master of the function as needed. .
