Transmitting a test command through the Internet according to a tester's operation, and the web server application interprets the command from the client and converts the test command into a test command, and converts the test command into TCP / UDP / IP. Passing to the maintenance application through the maintenance application, and the maintenance application queries the database for the validity of the test requested by the client, and tests the message through the middleware upon receiving the result of the query. Passing it to the executing application And a step in which the test execution application program analyzes the message from the maintenance application program, identifies a test target application program, and starts a test for the test target application program through the middleware. The target application program includes a process of conducting a test requested by the client through interaction with the test execution application program.

Then, the Node (a) performs the test function according to the test request, and notifies the Tester 1 of the result.

Existing networking-based large-capacity service systems (e.g. mobile communication systems, softswitch systems, etc.) provide various services to subscribers through interactions with multiple nodes performing specific functions for each service. . In order to perform other functions that are the same or different in function and role of each node, communication between nodes is required and according to the function of each node, the protocol stack and delivery are used. The content of the message is different. In order to verify the function of such a large-capacity networking system, a tester (Tester (1) to Tester (n)) capable of interworking and communicating with each node is required, and the test results are Tester (1) to Tester (n). Judgment is made based on the processed result between Node (a) and Node (b).

That is, the application programs applied to each node and executed to provide a service to subscribers through interaction with other nodes, and to the application programs applied and operated on each node. To test the function, a tester suitable for the node should be prepared and the connection between them should be configured according to the adjacent network.

As described above, the test apparatus according to the related art should exist separately for each function, and if a tester wants to test a specific function of the system, the tester moves to the place where the system is configured (the place where the test environment is provided). There are many problems such as temporal, spatial and environmental constraints such as having to perform a specific function according to a standard.

It is therefore an object of the present invention to provide an apparatus and method for testing a large capacity distributed networking system online over a network.

To this end, the present invention standardizes and unifies the Software Framework for testing. Standardize and unify the internal software framework of network-based systems and test equipment to provide services to subscribers. The software framework may be referred to as middleware in other terms. The middleware is a module that wraps based on primitives of an operating system, and provides functions for resources provided by the operating system (O / S) and also provides a function for distributed network systems. It is in charge of communication function. Since the service providing application made using the middleware and the application for testing have the same structure, it is possible to provide a tester integrated inside a single system.

4, the client 401 represents a personal computer used by a system administrator. Here, the tester and the operator must be registered in the database 407 of the maintenance node 403 providing the test. The client 401 provides a graphical user interface (GUI) that only an administrator who manages the system can use. Here, the system administrator controls the basic data by the test, such as registration / deletion / change, test items, configuration items for the test subscribers using the graphical user interface. The graphical user interface (GUI) is processed using, for example, JavaServer Pages (JSP) and servlets.

The maintenance node (OM Node) 403 is a node that maintains the test system and processes a test request from the client 401. The maintenance node 403 includes a web server application 404, a maintenance application 405, a plurality of applications 406 and a database 407 in charge of a test function as shown. do.

The web server application 404 provides a web server function, and can use general commercial and open web servers. The web server application 404 is connected to the client 401 via the HTTP protocol, and interoperates with the maintenance application 405 through a TCP / UDP / IP interface.

The maintenance application 405 is an application that is in charge of the operation and maintenance of the system, and is implemented as a middleware-based application. The maintenance application 405 communicates with a plurality of test execution applications 406 in charge of testing through middleware 408. The test request from the client 401 is transferred to the test execution application program, the test result from the test execution application program is stored in the database 407, and then the test result is stored in Extensible Markup Language (XML). After making it, the web server application 404 transmits it to the client 401.

The test execution applications 406 are applications that execute tests, and are implemented as middleware-based applications. After testing with only one application program, the result may be passed to the maintenance application 405 to terminate the test, but in general, the test is performed in conjunction with the target application and the result is maintained. Report to (405).

Target node 410 refers to a distributed networking system configured to provide services to subscribers. The target node 410 includes a plurality of applications 411 that provide a service. The applications 411 are applications that provide services to subscribers according to their purpose, and are implemented as middleware-based applications.

With the web browser running, enter the address of the maintenance node (OM Node) 403 to access the web page, authenticate the subscriber account, and then select an item for testing. At this time, if the basic data for the test is input to the form displayed through the GUI, the client 401 requests the test to the maintenance node 403 using the HTTP protocol in step 501.

The web server application 404 in the maintenance node 403 parses the command received from the client 401 in step 503 to convert it into a test command, and converts the test command into a TCP / UDP / IP interface. It passes to the maintenance application 405 through.

The maintenance application program 405 that receives the test command queries the database 407 through Structured Query Language (SQL) to confirm whether the request for the test and the basic data for the test are valid in step 505. do. Then, the database 407, in step 507, the result of the query for the maintenance application 405, such as the basic data for the test and system configuration information, the basic data for the test, the maintenance application 405 ).

In operation 509, the maintenance application program verifies the data received from the database 407, creates a command object based on this information, and then delivers a message for testing to the test execution application. . In operation 511, the test execution application 406 analyzes the message received from the maintenance application 405, converts the message into basic data for the test, and performs triggering for the test. At this time, check the application to be tested and start the test via middleware.

To pass. In operation 515, the test execution application 406 generates the test result as a predetermined data object and transmits the generated data object to the maintenance application 405.

In operation 517, the maintenance application program 405 converts the test result into a data record and requests the database 407 to store the data through an SQL query. The database 407 then stores the test results in step 519 and notifies the maintenance application 405 of the results.

In operation 521, the maintenance application program 405 converts the test result into XML and delivers the test result to the web server application program 404 through a TCP / IP interface. In step 523, the web server application 404 converts the test result received from the maintenance application 405 into a servlet and outputs the result to the monitor of the client 401.
