Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a client program automatic demonstration apparatus which operates in a server / client type window system.

[0002]

2. Description of the Related Art Generally, a window refers to an independent display area on the screen. In other words, the display screen is virtually divided into several rectangular areas, and each area is assigned to a different purpose, giving the appearance of looking through a "window" vacant on the display screen. I am trying to do. The window can be moved and deformed in dot units.

As a method of using a window, there is a method of assigning a task to each window, for example, a method of editing a program by an editor in one window and reading an electronic mail in another window. A large-scale programming is required to realize a window, and in the window system, common functions are extracted by using the window and the necessary primitives are collectively provided.

As a typical implementation method of the window system, there is a server / client method. That is, a server process that collectively manages windows,
It is a method of separating the service into a client process (application). This method
There is an advantage that the overhead in the code amount and the number of processes can be reduced, and further, there is also an advantage that the debugging is easy because the window system is realized as just one application. Then, in such a server / client type window system, there is an automatic demonstration device for automatically operating a client program.

FIG. 3 is a block diagram showing the basic structure and data flow of an automatic demonstration device of this type. Reference numeral 31 is an information branching unit for recording event information from a server, and 32 is an information branching unit. An information recording unit that records the event information branched by the unit 31, and an event reproducing unit 33 that sends the event information recorded in the information recording unit 32 to the client. Note that typical event information includes keyboard input, pointing input, input for window operation, instruction to redraw window contents, and the like.

[0006] In the automatic demonstration device configured as described above, when recording the data for the demonstration, the operator operates the key according to the scenario of the demonstration. Then, the information branching unit 31 receives the event information sent from the server to the client, which is generated by such key operation, and sends this information to the client and records it in the information recording unit 32.

Further, when reproducing the event information, the event reproducing section 33 reads the event information recorded in the information recording section 32 and sequentially sends this information to the client. Therefore, a demonstration is automatically performed by causing the client to perform the same operation as the operation performed by the operator during recording.

[0008]

However, in the above-mentioned automatic demonstration device, when the client issues a request for inquiring about the status of the server when the event information is reproduced, the operator is not actually operating. , The state of the server has not changed at all. Therefore, the server does not return the same response information to the client as when recording the data. Therefore, it is not possible to perform an automatic demonstration that asks the server status and operates according to the response information.

In view of the above situation, in the present invention, in the server / client type window system, even when the client issues a request for inquiring about the status of the server at the time of reproducing the event information, It is an object to provide an automatic demonstration device capable of returning the same response information to a client.

[0010]

In order to achieve the above object, the present invention is an automatic demonstration apparatus for a client program operating in a server / client type window system, wherein event information from the server to the client and the client to the server are used. Request information, and information branching means for branching each piece of information of response information from the server to the client in response to the request information, information recording means for recording the branched pieces of information in the order of their occurrence time, and the information recording. While the event reproduction means for sending the event information recorded in the means to the client is provided, when the event information is reproduced, the request information from the client is received and compared with the request information recorded in the information recording section, and if necessary, , Request processing that returns corresponding response information to the client It is characterized by comprising a stage.

The present invention further comprises an information branching unit for branching event information from the server to the client, and an information recording unit for recording the branched event information in order of occurrence time.
An event reproducing unit for transmitting the event information recorded in the information recording unit to the client is provided, and a virtual state reproducing the state change of the server occurred at the time of recording based on the event information transmitted from the event reproducing unit at the time of reproducing the event. It is characterized by comprising a server and a request processing means for receiving request information from the client when reproducing the event information and returning response information to the client according to the state of the virtual server if necessary.

[0012]

According to the above structure, the information branching unit branches the event information sent from the server to the client, the request information from the client to the server, and the response information of the server in response to the request. Then, each branched information is recorded by the information recording means.

Further, at the time of reproducing the event information, the event reproducing means takes out the event information recorded in the information recording means and sends it to the client, thereby causing the client to perform the same operation as at the time of recording each information. At this time, when the client makes a request to inquire about the status of the server, the request processing means extracts the response information corresponding to the request from the information recording means, and the extracted response information is the response from the actual server. Return to the client instead of the information. By doing so, it is possible to return to the client the same response information that was returned from the server during recording.

Similarly, at the time of reproducing the event information, the event reproducing means sends the event information recorded in the information recording means to the client and causes the virtual server to reproduce the state change of the server originally caused by the occurrence of the event information. You can also In this case, when the client makes a request for inquiring about the state of the server, the request processing means sends the response information corresponding to the request according to the state of the virtual server to the client instead of the response information from the actual server. return. By doing so, it becomes possible to return the same response information as returned from the server at the time of recording. In this case, it is not necessary to record the request information sent from the client to the server and the response information of the server to the request.

FIG. 4 is a block diagram showing a data flow in the first embodiment, (A) shows a data flow at the time of recording, and (B) shows a data flow at the time of reproduction. When performing an automatic demonstration, first, an operator performs a key operation or the like according to the scenario of the demonstration in order to record data for reproducing the operation of the client program. Then, as shown in (A), the information branching unit 41 sends the client the event information generated by the key operation or the like and sent to the client, and the information recording unit 42 records the event information. Also send. Further, in the course of the operation of the client program, request information issued from the client to the server and response information from the server to the request are also recorded in the information recording unit 42 via the information branching unit 41. In this case, the event information, the request information, and the response information are recorded in the order of occurrence thereof.

Next, when reproducing the operation of the previously recorded client program, the event reproducing section 43 first extracts the event information from the information recording section 42 and sends it to the client, as shown in (B). By doing so, the client program performs the same operation as when it was recorded. At this time, when request information is issued from the client to the server, this request information is once sent to the request processing unit 4.
Sent to 4. Then, the request information that does not require a server response is sent to the server as it is, and the request information that requires a server response is generated from the request order information and the content of the order of occurrence at the time of recording the request information. 44 retrieves the corresponding request information and the corresponding response information from the information recording unit 42, sends the retrieved request information to the server, and replaces the response information from the server for the sent request information with the information recording unit. The response information extracted from 42 is returned to the client.

The above operation will be described in more detail using a specific example. For example, consider reproducing the operation of pressing the shift key and then the A key. That is, when recording the motion, the operator presses the shift key on the keyboard,
If the A key is pressed without releasing the shift key in that state, when the A key is pressed, the client inquires of the server whether the shift key is also pressed, and the operation is performed depending on the result. Shall be changed. In such a case, information is generated in the following order ((1) → (4)), and the generated information is recorded in the information recording unit 42.

(1) The server sends the client the event information that the shift key has been pressed (2) The server sends the client the event information that the key A has been pressed (3) The client sends the server , The request information asking whether the shift key is pressed is sent. (4) The server sends the client the response information that the shift key is pressed as a response to the request information in (3). At times, the event reproducing unit 43 sequentially reads out the two pieces of event information recorded in the information recording unit 42 and sends them to the client. At this time, as in the case of recording, request information asking whether the shift key is pressed is issued from the client, and the request processing unit 44 receives this request information. When the request processing unit 44 determines that the request needs to be responded, the request information is sent to the server, and the response information corresponding to the request is taken out from the information recording unit 42.
Wait for the server's response to the request. After that, the request processing unit 44 receiving the response information from the server returns the response information read from the information recording unit 42 to the client instead of the response information. The information flow in this case is performed in the following order ((5) → (11)).

(5) The event information indicating that the shift key is pressed is sent from the event reproducing unit 43 to the client. (6) The event information indicating that the A key is pressed is sent from the event reproducing unit 43 to the client ( 7) Request processor 44 receives request information from the client asking if the shift key is pressed.

(8) The request processing unit 44 searches the information recording unit 42 and extracts the response information corresponding to the request information received in (7). The response information is the response information recorded in (4). (9) The request processing unit 44 sends the request information received in (7) to the server. (10) As a response to the request information of (9), response information that the shift key is not pressed is sent from the server, and the request processing unit 44 receives this response information.

(11) The request processing section 44 sends the response information extracted in (8) instead of the response information in (10) to the client. As described above, according to the first embodiment, the response to the request information from the client is made by the response information previously recorded in the information recording unit 42. Therefore,
The client can reproduce the same behavior as when recording it.

FIG. 2 is a block diagram showing the configuration of the second embodiment of the automatic demonstration device according to the present invention. In FIG. 2, 21 is an information branching unit for branching each information to record information flowing between the server and the client, 22 is an information recording unit for recording the information branched by the information branching unit 21, and 23 is an automatic demonstration. An event reproducing unit that extracts event information from the information recording unit 22 and sends it to the client, 24 also reproduces a change in the state of the server that occurred at the time of recording, based on the event information sent from the event reproducing unit 22 to the client during the automatic demonstration. Similarly, during the automatic demonstration, the virtual server 25 receives request information from the client to the server, and if a request requires a response, creates response information corresponding to the request information from the state of the virtual server 24. Is a request processing unit that sends the

The operation of the automatic demonstration device configured as described above will be described below with reference to FIG. FIG. 5 is a block diagram showing the flow of data in the second embodiment. FIG. 5A shows the flow of data during recording and FIG. 5B shows the flow of data during reproduction. When performing an automatic demonstration, first, an operator performs a key operation or the like according to the scenario of the demonstration in order to record data for reproducing the operation of the client program. Then, as shown in (A), the information branching unit 51 sends the client the event information generated by the key operation or the like and sent to the client, and the information recording unit 52 also records the event information. send. Then, this event information is recorded in the information recording unit 52.

Next, when reproducing the operation of the previously recorded client program, as shown in (B), the event reproducing section 53 first extracts the event information from the information recording section 52, and this is taken out by the client and the virtual server. Send to 52. By doing so, the client program performs the same operation as when it was recorded. In addition, the virtual server 54
The state of the virtual server 52 is changed according to the sent event information. Request information issued from the client to the server during the reproducing operation is once sent to the request processing unit 55. Then, request information that does not require a server response is sent to the server as it is, and request information that requires a server response is queried by the request processing unit 55 to the virtual server 54 for a response to the request information. Make information. As described above, the virtual server 54 sends the previous request information to the server, and returns the request information created from the state of the virtual server 54 to the client instead of the response information from the server to the sent request information.

The above operation will be described in more detail using a specific example. For example, let us consider reproducing the operation of pressing the shift key, then the A key, and then releasing the shift key. That is, if the operator presses the shift key on the keyboard at the time of recording the action and then presses the A key without releasing the shift key in that state, when the A key is pressed, the client also presses the shift key. It asks the server if it is pressed, and changes the operation depending on the result. In such a case, information is generated in the following order ((1) → (5)), and the generated information is recorded in the information recording unit 52.

(1) The server sends the client the event information that the shift key has been pressed (2) The server sends the client the event information that the key A has been pressed (3) The client sends the server , Request information is sent asking if the shift key is pressed (4) The server sends the client a response information that the shift key is pressed in response to the request information in (3) (5) The server sends the client The event information indicating that the shift key is released is sent to the event reproducing unit 53. Next, when reproducing the above operation, the event reproducing unit 53 sequentially reads the event information recorded in the information recording unit 52 and sends it to the client and the virtual server 54. The virtual server 54 changes the state of the virtual server 54 according to the sent event information. At this time, as in the case of recording, the client issues request information asking whether or not the shift key is pressed. The request processing unit 55 receives this request information. When the request processing unit 55 determines that the request requires a response, the request processing unit 55 sends the request information to the server and the virtual server 54.
, It creates response information and waits for a response from the server to the request. After that, the request processing unit 55 that receives the response information from the server returns the response information created from the state of the virtual server 54 to the client instead of this response information. The flow of information in this case is as follows ((6) → (1
6)).

(6) Event information indicating that the shift key is pressed is sent from the event reproducing unit 53 to the client and the virtual server 54. (7) The state of the virtual server 54 is changed to the state where the shift key is pressed. (8) The event information indicating that the A key is pressed is sent from the event reproducing unit 53 to the client and the virtual server 54. (9) The state of the virtual server 54 is changed to the state where the shift key and the A key are pressed. Change (10) The request processing unit 55 receives request information from the client asking whether the shift key is pressed.

(11) The request processing section 55 checks the state of the virtual server and creates response information corresponding to the request information received in (7). (12) The request processing unit 55 sends the request information received in (10) to the server. (13) As a response to the request information of (12), the server sends response information that the shift key is not pressed, and the request processing unit 55 receives this response information.

(14) The request processing section 55 sends the response information created in (11) instead of the response information in (13) to the client. (15) The event information indicating that the shift key has been released is sent from the event reproducing unit 53 to the client and the virtual server 54. (16) The state of the virtual server 54 is changed to the state where the shift key is not pressed.

As described above, according to the second embodiment,
The response to the request information from the client is made by the response information created from the state of the virtual server 54. Therefore,
The client can reproduce the same behavior as when recording it. In the first and second embodiments described above, the event information is recorded together with the recording time, and this time information is used during reproduction so that the event information is issued at the same time intervals as during recording. May be. Also, depending on the content of the request information during playback,
Instead of the response information prepared by the request processing units 14 and 25, the request information sent from the server at the time of reproduction may be returned to the client.

[0032]

As described above, according to the present invention, in the automatic demonstration apparatus for the client program which operates in the server / client type window system, when the event information is reproduced, the client asks the server about the state of the server. Even when a request for a response is issued, the same server response as when the event information was recorded can be returned to the client regardless of the actual server state. It is also possible to provide a virtual server and make a response to a request from a client depending on its state. Therefore, the client can accurately reproduce the operation as the same operation as at the time of recording, and the demonstration effect is extremely large.
