Description

Apparatus and method for testing interfaces of enterprise Java bean components {APPARATUS AND METHOD FOR TESTING INTERFACES OF ENTERPRISE JAVABEANS COMPONENTS}

The present invention relates to an apparatus and method for testing an interface of an Enterprise JavaBeans (EJB) component. In particular, the present invention has a user-defined object type parameter in addition to a server component interface method having a primitive type parameter. Server component interface methods also relate to apparatus and methods that allow for testing.

Typically, components are unit software that is independently deployed for software system development, and the functions possessed by the unit software must be checked to ensure the function of the entire component based system composed of components before using the unit component.

Also, since EJB component is deployed to application server and executed through client program, program execution method is different between general client and server. In particular, in order to call the function of a specific EJB component, the component must be pre-deployed on the application server, and the client program finds the specific EJB component deployed from the application server, and then executes a specific method from the external interface of the component. Will be obtained.

Here, an interface is a set of methods that are exposed to the outside to transmit / receive data with other components, and one component has a set of functional methods.

That is, each method constituting the EJB component interface consists of input parameters, method names, and return values, and the component interface tester checks which return value is produced for the input parameter for each interface method unit.

In other words, the client implementation can verify the performance of the interface method by creating a client to test the interface method based on the interface information the component has for testing the component interface, and selecting and executing a specific method from the automatically generated client. To ensure that

Therefore, the component interface test has a problem that the method name and the parameter object for the test must be passed at run-time, so that it is impossible to know at all which method with which parameter to test before the execution request.

That is, there are various limitations to the component interface test method that has been studied so far. It is necessary to generate as many client programs of the component to be tested as the number of interfaces. This creates the client program quite inefficiently, and if an object of a user-defined type is included in the input parameter of an interface method, it will not be able to support creation of a parameter of the user-defined type at run time. We had a problem that we could only test interface methods for methods that had a basic type.

On the other hand, as described above, the component is a software system development "A Software Component Verification Tool" published in November 2000, "Quality certification method for software quality certification" filed in the application number 1998-2843, It is disclosed in the "real-time Internet test method using a three-layer structure" filed in the application number 2000-39118.

That is, in detail describing the disclosed prior art, "A Software Component Verification Tool" published in November 2000 defines a library of repeatedly used software as a reusable software unit, that is, a component, so that the component is functional. Automatically creates an environment to test for proper operation. Test methods are divided into symbolic test methods for conditional testing of specific methods and literal test methods for obtaining or collecting test results. Each method is divided into a test case generation and an automatic test pattern generation for a test component. When a test specification is described, it can be read universally by describing it in an extensible markup language (XML). It also provides component test results in XML format. When you create a test case, you specify the test path that must be taken to design the portion of the test run that is required for the test. In other words, test results are generated for each condition of the module to be verified and for each return value returned without accessing the source code for each library module.

Next, "Quality certification method for software quality certification" filed in the application number 1998-2843 is connected to the component server developed by the application developers for the software quality certification to the verification server of the functional certification authority to test the quality certification This process is designed to shorten the time required to develop or apply another application program by providing an authentication number on the Internet for the component software to be verified.

Finally, "Real-time Internet test method using three-layer structure" filed in the application number 2000-39118, divides the Internet business model using the EJB component into the presentation layer, business logic layer, data layer, and connect the three layers Thus, when a user requests to execute a function, a real-time Internet test is performed using a three-layer structure of a presentation layer, a business logic layer, and a data layer. The user's request entered through the presentation layer is made through the processing of the business logic layer associated with the database of the data layer, and the data load can be balanced through the partitioned data layer to handle the functional test requests of multiple users. To ensure that

As such, when looking at the techniques disclosed in the prior papers and patent applications, the existing known techniques include a specific method having an object parameter input for an interface method delivered at runtime in an automatically generated tester proposed by the present invention. There is still a problem that falls short of having to do this.

Accordingly, the present invention has been made to solve the above-mentioned problems, and its object is to provide a web that can test server component interface methods having parameters of object types defined by users in addition to server component interface methods having parameters of basic types. Support for auto-generating the client makes it easy to set initial values for user-defined object parameters and pass parameters to test methods, allowing you to test component interfaces produced based on Enterprise JavaBeans (EJB). The present invention provides an apparatus and method for testing an interface of an EJB component.

In the present invention for achieving the above object, the interface testing apparatus of the enterprise Java bean (EJB) component is the interface method test result in response to the functional request and request of the EJB component interface method to the interface with the EJB component user (interface) A user interface graphical interface for controlling; It automatically analyzes EJB components according to the client program automatic generation request for testing interface of EJB component provided through user interface graphical interface.

The EJB analyzer 120 automatically analyzes EJB components according to EJB component requirements provided through the user access graphical interface 110, and has a class file composed of a package as an interface, and analyzes which methods are included in the interface. As a block to execute, EJB interface information is analyzed by dividing package path information of home interface class file and remote interface class file and method signature information included in each into method name, method parameter type and return value. The analysis information S1 is provided to the component test client generator 130.

The component test client generator 130 repeatedly inputs and modifies the component name information (Java Naming and Directory Interface (JNDI)) to find the corresponding component deployed in the application server. The name information and user of the deployed component are supported. If the name of the component you want to search for does not match, enter the modified component name repeatedly so that you can proceed with the testing of the server component interface methods. Also, the Java Server Page (JSP) As a block for generating a web client program for selecting an interface method, creating a parameter object, expressing a created parameter object, and managing a parameter object using a template file, EJB interface analysis information provided from the EJB analyzer 120 (S1). Web-based EJB client It provided with a screen as shown in Figure 3 to Figure 4 to generate a program. Here, the user accesses the EJB component interface test results as shown in the message window window of FIGS. 3 to 4 so that the EJB component user 200 can select the server component interface method to inquire the test request result. Provided to the EJB component user 200 through the graphical interface (110). JSP template file is composed of web layout part and logic generation part for interface test, and it operates by classifying interface and called method parameter type.

In addition, the component test client generator 130 connects to the object parameter generator 150 and requests to generate a parameter object of a user-defined type for a method having a parameter of a user-defined type.

The object presenter 140 analyzes and expresses member variable and member function information included in the parameter of the object type, and selects a member function to support setting an initialization value to a specific member variable.

The object parameter generator 150 analyzes and provides a member variable and a member function with respect to a parameter of an interface method, and uses the analyzed member function as a block to support setting the member variable to a desired parameter value by a component test client According to the creation request of the parameter object for the user-defined type from the generator 130, the parameter manager generates a parameter object necessary for examining the interface method, and generates a parameter type file for enabling the stored parameter object to be stored permanently. 160). Here, as shown in FIG. 6, the parameter type generated by the object parameter generator 150 may be classified according to Java parameter types. Referring to FIG. 6, the parameter type of the interface method input from the EJB component client may be a basic type or a reference type. It is divided into complex type and user defined type. Here, when Java's base type and reference type are combined and specified as a base type, and a complex type and a user type are specified as an object type together, object creation processing for the base type uses the default type object parameter values that are introduced at runtime. Creates a parameter object for the base type, and the object creation process for the object type is configured to test the parameter value in the member variable by analyzing the class and member function information of the object type using Java reflection. Create a parameter object as one.

In response to the client creation request, the EJB analyzer 120 analyzes interface information of the provided EJB component (step 303).

Thereafter, the component test client generator 130 generates a web-based EJB client program as shown in FIG. 3 according to the EJB interface analysis information S1 provided from the EJB analyzer 120 (step 304).

Examining the interface in which the EJB client program is generated The EJB component user 200 is provided through the user-connected graphical interface 110 (step 305), and the interface method execution request and the object parameter generation request are provided through the user-connected graphical interface 110. If input (step 306), it is determined whether there is an object representation request (step 306-5).

When the object representation request is made in the determination step 306-5, the object parameter generator 150 provides the object manager 160 with the object name of the parameter type provided from the component test client generator 130 (step In step 307, it is checked whether the object is provided by the object manager 160 (step 307-5).

If the object is not provided by the object manager 160 in the check step 307-5, the object parameter generator generates an object parameter (step 308).

When the object is provided by the object manager 160 in the check step 307-5, the object presenter 140 analyzes and expresses the member variable and member function information of the parameter of the object type and expresses the member function. Select to set an initialization value to a specific member variable, and if it contains a user-defined type of internal parameters recursively, it supports recursively representing the internal object (step 309), and recursively for the internal object In general, when object parameter management is requested 311, the process repeats the process from step 307-5, and terminates when no object parameter management is requested.

Subsequently, the object manager 160 determines whether there is an object management request (309-5), and when there is an object management request, the object manager 160 uses a parameter of a type defined by a user in the file of the parameter object generated by the object parameter generator 150. Save and manage to assign as an input value to the interface method having a (step 310).

For reference, the interface test client of FIG. 3 provided by the component test client generator and displayed in a web browser is a web client program for a component for testing a function that changes dollars to yen and yen to euros. Screen. The name of the component to find the deployed component can be changed by changing the Java Naming Directory Interface (JNDI) name.After executing the home interface to obtain the remote interface object, the method of the remote interface is tested and verified. . The test of the method is performed by selecting an execution button called "run" in the screen shown in FIG. The test result for the selected method is displayed as the test result of the yenToEuro and dollarToYen execution of the remote interface and the home interface create method in the message window part below FIG. 3.
