Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a web server system and a method for executing a web application by the web server system.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram for explaining a web application execution method by a conventional web server device. The web server device 3 sends the requested UR
L, a web server program 4 for returning a web document as a response or executing a web application and returning the result. The web server program 4 receives the request (URL) transmitted from the browser 2 on the web client 1 and the input information to the web application 8, and if the URL transmitted from the browser 2 is a request for the web document 7, The content of the web document is transmitted, and if the request is to the web application 8, the input information is transmitted to the web application 8, executed, and the result is transmitted to the browser 2. The web document 7 is an HTML document, and one file is created for each URL. The web application 8 is a program that outputs an HTML document as an output at the time of execution, and one file is created for each URL.

As shown in FIG. 2, a conventional web server system operates by transmitting a request (URL) input to a browser 2 operating on a web client 1 to a web server on a web server device 3 via a network. The communication processing unit 5 of the program 4 receives the data. The processing unit 6 of the web server program 4 uses the UR received by the communication processing unit 5
If the file specified by L is a web document (HTML file or the like) 7 that displays the contents of the file on the browser 2 as it is, the contents of the file are directly transmitted to the web client 1 via the communication processing unit 5 and the network. Is displayed on the browser 2. When the file specified by the URL is a web application 8 that executes a program of the file and displays an output result at the time of execution on the browser 2, the web application is executed, and the output result is transmitted to the communication processing unit 5 and the network. Via the browser 2 on the web client 1.

[0004] When the web application 8 is executed, the request from the browser 2 includes not only the URL but also the input value to the browser 2. The input value is, for example, user information or a password that is input when accessing a URL that requires user authentication, or a credit card number that is input during Internet shopping.

However, in the prior art, the processing unit 6 of the web server program 4 has neither an interface with the input device nor an interface with the output device, and outputs the data to the web client 1 via the communication processing unit 5 and the network. Is output only to the browser 2. Therefore, data cannot be input from the web server device 3 to the processing unit 6 while the web application 8 is being executed.
Output of the web application 8 to the web server device 3
Also cannot be displayed.

In general, in testing a program, the program is executed via software called a debugger. By passing through the debugger, the program can be stopped while the program is being executed, and processing such as referring to the value of the variable at that time, executing while changing the value of the variable, and executing repeatedly can be performed. At this time, it is necessary to input character information such as a command for referring to a variable to the debugger. In addition, an interface for displaying a command execution result is required.
Therefore, when testing a web application that does not have an input unit and an output unit, a debugger used for testing a general program cannot be used. Therefore, when performing a test, a method of outputting a variable value to the browser 2 by adding an output unit of a test variable in a web application, or a method in which the web application 8 does not pass through the web server program 4 You will use a debugger to execute it.

There is also a technology in which a web server is provided with an input unit and an output unit in order to address the above problem, and a debugger function is added. However, this technology can be used in a general-purpose web server. No, you need to use a web server program that incorporates this technology.

[0008]

The conventional web application testing method has the following problems.
First, when an output unit for a test variable is added to a web application, it takes time and effort to add it. If the variable to be referenced is not clear, a large number of output units must be added. Also, when finally moving from the test environment to the production environment, it is necessary to delete the added part. As described above, this method requires a lot of time and requires only an inadequate test. For example, the test requires a lot of time and effort to test only the value of a variable.

Next, when the web application is executed via the debugger, the user name and password values input from the browser 2 are obtained as input values to the web application in a normal web application execution method. However, in the case of this test method, since the test is executed without passing through the browser 2, a value to be input from the browser 2 is not input to the web application 8. In the case of a normal execution method of executing the web application 8 via the web server program 4, there are variables of the execution environment set by the web server in addition to the input value from the browser 2. This variable contains the browser 2 version and web client 1
IP address and the like. For this reason, when performing tests using this method, input values such as user names and passwords and variables of the execution environment set by the web server are directly described as the values of variables in the web application file, and the debugger commands It is necessary to take a method such as setting the value of a variable during execution using. Therefore, in this method, it is difficult to perform a test in the same situation as when the web application is actually executed from the web server, such as an input value from the browser or a value of an execution environment variable set by the web server.

There is also a web server software product in which a debugger function is added to a web server.
When using this product, testing is efficient, but it can only be used with web applications written in the programming language that can be used with this software product,
Because of the need to use this web server software product, a number of web server software products are already widely used today, and each software has its own characteristics, so it is not easy to change the web server software. Can not.

The present invention has been made in view of the above-described problems of the prior art, and has been described in relation to the execution of a web application having an insufficient test environment while using a general web server program and a general web application execution method.

FIG. 4 is a flowchart showing an example of an operation procedure when a web application is interactively executed by the web server system of the present invention. Here, a method of executing a web application via a debugger to debug the web application will be described.

Data and a request are transmitted from the web browser 2 to the URL (S11), and the web server program 4 that has acquired the data and the request executes the web application interface 9 (S11).
12). The executed web application interface 9 executes the web application management server program 10 according to the information described in the file. At this time, the data transmitted from the browser 2 is set as an environment variable, and the execution is performed using the path to the web application 8 and the path to the debugger as arguments (S13). The path of the debugger may be provided in the web application interface or the web application management server program.

The executed web application management server program 10 executes the web application 8 via the debugger 15 according to the argument. At this time, the value of the environment variable set in the web application interface 9 is obtained, set again as an environment variable, and executed (S14). The output result of the debugger 15 is transmitted to the input / output unit 22 of the web application management client device 16.
Is displayed (S15). A command is input to the web application management client program 17 using the input / output unit 22 of the web application management client device 16 (S16).

If the input command is an output switching command in which the output destination is the web browser 2, step 1
Then, the process proceeds from step 7 to step 22 to switch the output from the debugger 15 to the web browser 2. If the input command is not the output switching command, the debugger executes the command (S19). The execution result is stored in the input / output unit 22 of the web application management client 16.
Is displayed (S20). Subsequently, a command is input to the web application management client (S2).
1). Thereafter, the processing from step 17 is repeated.

When the output destination is switched to the web browser according to the determination in step 17 (S22), the operation other than the output destination being the web browser 2 is the same as the operation from step 18 to step 21. By switching the output destination to the web browser, the output status of the web browser 2 as the final purpose can be grasped. Therefore, after performing a sufficient test in a loop from step 17 to step 21, the output destination is switched, By following the procedure of instructing the debugger 15 to re-execute the application,
Tests inside the program can be performed in steps 17 to 21, and tests for external specifications can be performed in steps 24 to 27. FIG. 5 and FIG.

The web application management server program 43
The output result from the web application is output to the web application management client program 45 (step 44). The web application management client program 45 displays the output result on the screen.

When the web application is to be tested, a variable value for the web application and a debugger command such as step execution are input from the web application management client program 45 (step 49). The web application management client program 45 inputs the input debug command to the web application management server program 47 (Step 46). The web application management server program 47 inputs the input debug command to the web application (Step 48). The web application operates repeatedly from step 40 again.

The output result from the web application 41 is stored in the web application management client 4.
If the user wants to display on the web client instead of 5, the user inputs a default output switching command as an input to the web application management client 45 (step 49). As a result, the output result from the web application after this is stored in the web application management server 4
5 to the web application interface 51 (step 50), the web application interface 51 outputs the output result to the web server 53 (step 52), and the web server 53 outputs the output result to the web client 55 (step 54). . The web client 55 displays the output result on the screen of the browser.
