Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test result collating method for collating test results of inter-process communication in a real-time processing system including a plurality of processes. Real-time processing systems such as various switching systems and data transmission systems include processes that perform various processes such as call processing, control information transmission / reception processing, and switching connection processing. Each process includes data and processing necessary for processing. The result data and the like are transmitted and received. Communication is performed between such a plurality of processes, and normality of the real-time processing system is confirmed by testing whether or not this communication is normally performed.

2. Description of the Related Art In a real-time processing system,
For example, as shown in FIG. 3, a plurality of processes A, B,
Including C, ... X, operating system (O
S), and messages are transmitted and received among the processes A, B, C, ... X.

For example, as shown in FIG.
Sends to process B (1) and to process C
(2) Wait for reception (3). When it is received from process B (4), it is sent to process B as necessary (5).
, Wait for reception again (3). When it is received from the process C (6), it is sent to the process C (7) if necessary, and the reception is waited again (3).

The interprocess communication test, for example, as shown in FIG. 5, creates and executes expected operation data indicating an expected operation sequence, and the operation result data obtained thereby is collated with the expected operation data. Check normality. In that case, the expected operation sequence shown on the left is that process A sends data a to process B, and process B
From process B, then send data c to process B, receive data d from process B, then send data e to process C, receive data f from process C, and also process C. Sends data g to process X,
The case where the data h is received from the process X is shown.

For such an expected operation sequence,
The operation result sequence, as shown on the right side, is process A
After sending data a to process B and before receiving data b from process B, it sends data e to process C, and process A receives data b from process B and sends it to process B. After sending data c, process C
There is a case where the sequence is such that the data f is received from.

[0006]

As described above, in the inter-process communication test, expected operation data is created and executed, and operation result data resulting from the operation is collected and collated with the expected operation data. In that case, as shown in FIG. 5, the expected operation sequence and the operation result sequence are different because the plurality of processes are related to each other. Therefore, even if the expected operation data and the operation result data are sequentially collated, the order thereof is changed in a complicated manner, so that the collation work requires a lot of manpower and time. An object of the present invention is to simplify the collation process and also enable automation.

[0007]

A test result collation method according to the present invention collates expected operation data of a plurality of interprocess communication with operation result data of a result of execution of the expected operation data, and a plurality of processes are compared. In a method for testing a real-time processing system for transmitting and receiving messages between processes, a process table 1 showing a combination of processes A, B, C, ... , A sequence table 2 in which communication data between processes according to an expected operation sequence is tabulated, and operation result data as a result of executing interprocess communication based on the expected operation data is collected, and the operation result Based on the data, the process table 3 showing the combination of processes that have communicated, and the process table 3 in the area according to the process table 3 A sequence table 4 in which communication data is written and formed into a table is formed, and the process table 1 and the sequence table 2 of the expected operation are compared with the process table 3 and the sequence table 4 of the operation result. It includes.

Process tables 1 and 3 show combinations of processes A, B, C, ... Performing communication, and sequence tables 2 and 4 show transmission / reception directions between processes and communication data. It is stored in the area corresponding to the combination. Therefore, due to the association between multiple processes,
Even when the operation result data is obtained in a time order different from the expected operation sequence, if normal interprocess communication is executed, the process table 3 and the sequence table 4 are formed, and the process table 1 of the expected operation and the process table 1 It is the same as the sequence table 2. Therefore, the collation of the process tables 1 and 3 and the collation of the sequence tables 2 and 4 can be easily performed on the display.

Further, in the process of forming the process tables 1 and 3 and the sequence tables 2 and 4, the expected operation data or the operation result data is read for each message, and the combination of processes for transmitting and receiving this message is the process. Determine if it exists in Tables 1 and 3,
If it does not exist, this process combination is written to process tables 1 and 3, and this process table 1 and 3 is written.
The transmission / reception direction of the message and the content of the message are written in the areas of the sequence tables 2 and 4 corresponding to the combination of processes.

The process tables 1 and 3 show combinations of processes A, B, C, ... Communicating with each other. Therefore, the expected operation data or the operation result data of the inter-process communication is set for each message. Since it is possible to identify the transmission / reception process, it is searched whether or not the combination of the transmission / reception process exists in the process tables 1 and 3, and if it does not exist, it is a new process combination. Process table 1,
Write to 3. By repeating such processing, the process tables 1 and 3 can be formed using the expected operation data and the operation result data. Sequence again
Tables 2 and 4 are formed by the areas corresponding to the combination of the processes. For example, in the area of the combination of the processes A and B, the transmission / reception directions from the processes A to B and B to A and the contents thereof are shown. Write. Therefore, for the same combination of processes, the contents of the expected operation sequence table 2 and the operation result sequence table 3 are the same under normal conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory diagram of tabulation of an embodiment of the present invention, in which expected operation data and operation result data, expected operation process table 1 and sequence table 2 and operation result The main parts of the process table 3 and the sequence table 4 are shown. The process tables 1 and 3 include processes A, B, C, and
.., sequence table 2, 4
Are processes A, B, C of process tables 1 and 3,
.. has a region corresponding to the combination of ..., In each region, the transmission / reception direction of the message and its contents are written, and the expected operation data and the operation result data are tabulated.

For example, the process tables 1 and 3 include a combination of processes A and B for performing inter-process communication, a combination of processes A and C, ... A combination of processes A and X, a combination of processes B and C ,. ..A combination of processes C and X is written and formed. In the sequence tables 2 and 4, the communication data a, b, c, d between the processes A and B are written together with the transmission / reception direction in the area corresponding to the combination of the processes A and B. Communication data e and f between the processes A and C are written in the corresponding area together with the transmission / reception direction, and communication data g and h between the processes C and X are transmitted and received in the area corresponding to the combination of the processes C and X. It is written and formed with.

As expected operation data, processes A to B
When the data to (From A to B) and then the data from the process B to the process A (From B to A) are set and executed, the operation result data is output from the process A according to the execution order. B (Fro
Data from m A to B) may be followed by data from process A to C (From A to C). For example, process A sends data a to process B as in the expected operation sequence of FIG.
When indicating that the data b is received from the process B,
As in the operation result sequence, process A is process B
Data a may be transmitted to process C, and then process A may transmit data e to process C.

Such operation result data is collected, the process combinations that have been subjected to inter-process communication are written in the process table 3, and a sequence corresponding to the process combination is displayed.
In the area of the table 4, the communication data between the processes are sequentially written together with the transmission / reception direction. Therefore, even when the data e is transmitted from the process A to the process C before the process B is transmitted to the process A, the area between the processes A and B is stored in the area of the sequence table 4 corresponding to the combination of the processes A and B. The transmission / reception data and the transmission / reception direction are written, and the transmission / reception data between the processes A and C and the transmission / reception direction are written in the area of the sequence table 4 corresponding to the combination of the processes A and C.

(b) If it is finished, the table forming process is terminated.-If it is not finished, it is judged whether or not there is a combination between processes in the process tables 1 and 3 (c), and if there is, a step (e) Process table 1, if there is no process table 1,
Add a new process combination to 3 (d). That is, the expected motion data or motion result data such as "From
“Y to X” is searched for the presence / absence of a combination of the processes X and Y in the process tables 1 and 3, and if there is no such combination, a new combination of the processes X and Y is written in the process tables 1 and 3. .

Then, the transmission / reception direction of the message and its contents are written in the sequence table (e). For example,
“From A to B” indicates that the process A is transmitted to the process B, and if the data after that is a, the sequence table 2 corresponding to the combination of the processes A and B of the process tables 1 and 3 is shown. , 4 are written in the area of A → B as the transmission / reception direction and a as the data. Similarly, the process tables 1 and 3 and the sequence tables 2 and 4 are formed.

[0019]

A process table 3 that collects result data and indicates a combination of processes that have performed inter-process communication, and a sequence table 4 that writes inter-process communication data and a transmission / reception direction thereof in an area corresponding to the combination of processes. Form and Process Table 1,3
By comparing the sequence tables 2 and 4, the normality of interprocess communication is determined.

Therefore, even if the operation result sequence differs from the expected operation sequence due to the relationship between a plurality of processes, the table is used to compare the process result combinations so that interprocess communication of different process combinations can be achieved. There is an advantage that it is not affected, collation becomes extremely easy, and automation becomes possible. Further, not only the sequence corresponding to the combination of the processes but also the data can be collated, and there is an advantage that a highly reliable collating method of the test result can be provided.
