Abstract

PURPOSE:To analyze a fault in a short time by deciding automatically whether an error occurred or not with a tested instruction. CONSTITUTION:A test environment setting means 21 sets an executing environment of a tested instruction at a CPU 30. A tested instruction executing means 22 carries out the tested instruction through the CPU 30. An executing result deciding means 23 decides whether the executing result is normal or not through the CPU 30. A test environment setting means 41 sets a test environment again at a CPU 40 if the result of the first execution carried out the means 22 is not normal, and the set test carried out the means 22 is not normal., and the set test environment setting information is taken over by the means 22 which carries out the second execution. An executing result deciding means 42 takes over the executing result of the second tested instruction from the means 22 which carried out the tested instruction at the CPU 30. Then the means 42 decides whether the second executing result of the tested instruction is normal or not through the CPU 40.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a test execution system of an information processing apparatus of the present invention. 2 is a flow chart showing an example of the operation of the execution control means of FIG.

In the test execution method of the information processing apparatus of the present embodiment shown in FIG. 1, the test environment setting means 21 for setting an execution environment for executing an instruction operating on the CPU 30 to be tested and the above-mentioned on the CPU 30. An instruction under test executing means 22 for executing an instruction under test, an execution result judging means 23 which operates on the CPU 30 and judges whether or not the result of executing the instruction under test is normal, and an instruction under test executing means 22 When the execution result determining means 23 determines that the execution result of the first instruction of the test under test is not normal, it operates on the CPU 40, sets the test environment similar to the test environment setting means 21, and is set. The test environment setting means 41 that takes over the test environment setting information to the test instruction executing means 22 that executes the test instruction for the second time operates on the CPU 40, and on the CPU under test 30. Information of the execution result of the second instruction under test is inherited from the instruction under test execution means 22 that has executed the test instruction, and the execution result determination means 42 for determining whether the second execution result is normal or not. It is composed of an execution control means 10 for controlling the operation and a CRT display 50 for displaying the test result.

In FIG. 1, the CPU 30 and the CPU
40 is included in the information processing device to be tested, and in this embodiment, the CPU 30 is the CPU to be tested. The test program 20 is a program for operating on the CPU 30 under test to test the CPU 30,
The test environment setting means 21, the test instruction executing means 22 and the execution result determining means 23 shown in FIG.
Is realized on the CPU 30.

The test program 43 is executed by the CPU 40.
The test environment setting means 41 and the execution result determining means 42 which operate above and are shown in FIG. 1 are realized by the operation of the test program 43.

Next, the operation will be described.

In FIG. 1, when the test program 20 is activated, the execution control means 10 reads the test program 20 into the main memory and sets the execution CPU (CPU on which the test program is executed) in the CPU 30 (step 6).
0).

Next, the execution control means 10 activates the test environment setting means 21 (step 61). The activated test environment setting means 21 sets a test environment for executing the instruction under test. When the test environment is set, the execution control means 10 then activates the instruction under test executing means 22 (step 62), and the activated instruction under test executing means 22 executes the instruction under test. After the instruction under test is executed, the execution control means 10 activates the execution result determining means 23 (step 63), and the execution result determining means 23 compares the execution result of the instruction under test with the expected value. (Step 6
4) If they do not match, an execution result error occurs.

For example, taking an addition instruction as an example, when the addition result of "data A" and "data B" becomes "data C", the value of "data C" which is the execution result of the addition instruction, An error is detected by comparing the expected value of the addition operation of "data A" and "data B".

Next, if the execution result is an error, the instruction under test is re-executed as follows.

First, the execution CPU is set in the CPU 40 (step 65), and the test environment setting means 4 on the CPU 40 is set.
1 is activated (step 66). Test environment setting means 41
Sets the test environment for executing the instruction under test by the same operation as the test environment setting means 21. Then run C
The PU is set in the CPU 30 (step 67) and the instruction under test executing means 22 is activated (step 68). And
The instruction under test execution means 22 executes the instruction under test.

Next, the execution CPU is set to the CPU 40 (step 69), and the execution result judging means 42 on the CPU is activated (step 70). The execution result judging means 42
By the same operation as the execution result judging means 23, the execution result of the instruction under test is compared with the expected value, and if they do not match, an execution result error is determined. Then, the execution result is displayed on the CRT display 50 (step 71).

That is, when the expected value of the addition operation and the execution result do not match and an error occurs, the test environment setting means 41 and the execution result judging means 42 are operated next,
If an error still occurs, it can be determined that the instruction under test has an error. And the test environment setting means 4
1 and the execution result judging means 42 are operated, and when no error occurs this time, it can be judged as an error of the test environment setting means 21 or the execution result judging means 23.

As described above, when the execution result of the test program results in an error, the process other than the instruction under test is re-executed on the CPU, and the result is displayed so that the result can be compared. Whether or not an error has occurred is automatically determined, and failure analysis can be performed in a short time.

The execution of the instruction under test described above is
Execution of a single instruction or execution of a combination of a plurality of instructions may be performed.

[0022]

As described above, according to the test execution method of the information processing apparatus of the present invention, when the execution result of the test program results in an error, the process other than the instruction under test is executed again on the CPU. By displaying the results so that they can be compared with each other, it is possible to automatically determine whether or not an error has occurred in the instruction under test, and it is possible to perform the failure analysis in a short time.
