DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic test device used for testing a software program of a storage program controlled electronic exchange.

[Conventional technology]

Conventionally, when automatically testing the software program of a storage progera 11-controlled electronic exchange, a tester would sequentially input previously created commands into the electronic exchange's central processing unit from the input/output terminal of the electronic exchange according to the test procedure. Then, the message data output from the electronic exchange as a result of the execution of the input command is manually analyzed.

[Problem to be solved by the invention]

As mentioned above, in conventional automated testing of software programs for electronic exchanges, the scope of testing is limited to command tests, and in particular, when testing the communication line system, the tester must operate the communication line equipment. Furthermore, there is a problem in that data analysis of test results must be done manually.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic test device that automatically executes a test of a software program of an electronic exchange and determines whether the software program is good or bad.

The automatic test device of the present invention is connected to a central processing unit of a storage program controlled electronic exchange via a system bus, and receives a first control signal from the central processing unit and transmits an operation signal to the central processing unit. a communication path system input/output means for transmitting data; a communication path system simulating means for simulating the operation of telephones and trunks and connections of communication path switches according to a first control signal received from the communication path system input/output means; and a man-machine. a man-machine interface input/output means that connects to the central processing unit via an interface line and transmits commands and second control signals to the central processing unit and receives messages from the central processing unit; first storage means for storing test procedures; and, in accordance with said first storage means, said operating signal.

an automatic execution means for transmitting the command and a second control signal to the central processing unit; a test execution history by the automatic execution means; a simulation result by the communication line system simulation means; and the man-machine interface input/output means. a second storage means for storing test result data consisting of the received message; a third storage means for storing reference data of correct test results; and a comparison between the test result data and the reference data. and determining means for determining whether the test is good or bad.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The automatic test bag 'a, 1 shown in FIG. 1 is connected to a central processing unit 4 via a system bus 2 and a man-machine interface line 3. The automatic test equipment 1 receives control signals for the communication path system from the central processing unit 4 and
communication path system input/output means for transmitting operation signals to the communication path system input/output means; communication path system simulating means 6 for simulating connection according to the communication path system control signal received from the communication path system input/output means 5; and central processing unit 4. A man-machine interface input/output means 7 for transmitting commands and control signals to the central processing unit 4 and receiving messages from the central processing unit 4; a test procedure file 10 for storing predefined test procedures; and a test procedure file 10 for operating according to the test procedure file 10. automatic execution means 8 for transmitting signals, commands and control signals to the central processing unit 4;
and a test result file 11 that stores test result data consisting of the test execution history by the automatic execution means 8, the simulated results by the communication path system simulation means 6, and the messages received by the man-machine interface input/output means 7; It is comprised of a reference file 12 in which reference data of test results is stored, and a determining means 9 that compares the test result data with the reference data and determines whether the test is good or bad.

When the power of the automatic test equipment 1 is turned on by the tester,
The automatic test equipment 1 is activated, and the communication path system input/output means 5
Receives communication line system control signals transmitted from the central processing unit 4. This control signal is analyzed by the communication path system simulating means 6 and sent to the telephone set.

A man-machine interface input/output means 7 that simulates connection operations of trunks and communication path switches and stores the results in a test result file 11 is connected to the central processing unit 4.
The message received from the test result file 11 is stored in the test result file 11. The automatic execution means 8 reads the test instruction information from the test procedure file 10 created in advance, and for the call path system operation instructions, the call path system simulating means 6 simulates the operation of the telephone and the trunk, and transmits the operation signal to the call path. The operating signals are transmitted to the central processing unit 4 by the system input/output means 5 and sequentially stored in the test result file 11. If the test instruction information is a command or control signal to be input to the central processing unit 4, the man-machine interface input/output means 7 transmits it to the central processing unit 4 and sequentially stores it in the test result file 11. The determining means 9 is
Every time one test item is completed, the data in the test result file 11 and the data in the standard file 12 are logically compared, a pass/fail judgment is made for each test number included in the test item, and the results are It is stored in the test item management file 13. After completing the test, the tester can read the results from the test item management file 13 and display the pass/fail judgment on the display section of the determining means 9 by inputting a test result confirmation command.

〔Effect of the invention〕

As explained above, the present invention includes a means for simulating a communication line system, an input/output means for interfacing with an electronic exchange, a means for storing test procedures, test results, and reference data, and a means for automatically executing a test. Since the means and the means for determining the test results are provided, there is an effect that automatic test execution and pass/fail determination of the software program of the electronic exchange can be performed efficiently.
