Abstract

Based on a seed value held by a managing apparatus for a plurality of information processing apparatuses, the same number of seed values as the total number of times of tests conducted by one or more processing units included in an information processing apparatus are generated so as not to overlap with another information processing apparatus. Then, a processing unit of the one or more processing units generates the same number of test instruction sequences as the number of times of tests performed by the processing unit based on the same number of seed values as the number of times of tests performed by the processing unit among the generated seed values, and executes the generated test instruction sequences.

Claims

1. A test method comprising:

generating, by a processing unit of one or more processing units included in an information processing apparatus among a plurality of information processing apparatuses, a fist number of test instruction sequences based on the first number of seed values among a second number of seed values generated based on a seed value held by a managing apparatus for the plurality of information processing apparatuses so as not to overlap with another information processing apparatus, the fist number being same as a number of times of tests conducted by the processing unit and the second number being same as a total number of times of tests conducted by the one or more processing units; and

executing the fist number of test instruction sequences by the processing unit.

2. The test method according to claim 1, further comprising:

receiving the seed value held by the managing apparatus from the managing apparatus by the processing unit;

generating the second number of seed values based on the received seed value by the processing unit; and

updating the seed value held by the managing apparatus with a seed value different from the received seed value by the processing unit.

3. The test method according to claim 1, further comprising:

checking lock information held by the managing apparatus for exclusive control between the plurality of information processing apparatuses by the processing unit;

changing the lock information to a lock state by the processing unit when the lock information indicates an unlock state;

receiving the seed value held by the managing apparatus from the managing apparatus by the processing unit;

generating the second number of seed values based on the received seed value by the processing unit;

updating the seed value held by the managing apparatus with a seed value different from the received seed value by the processing unit; and

returning the lock information to the unlock state by the processing unit.

4. The test method according to claim 1, further comprising:

sending a notification of the second number of times of tests to the managing apparatus by the processing unit; and

receiving the second number of seed values from the managing apparatus by the processing unit.

5. The test method according to claim 1, further comprising:

checking lock information held by the managing apparatus for exclusive control between the plurality of information processing apparatuses by the processing unit;

changing the lock information to a lock state by the processing unit when the lock information indicates an unlock state;

sending a notification of the second number of times of tests to the managing apparatus by the processing unit;

receiving the second number of seed values from the managing apparatus by the processing unit; and

returning the lock information to the unlock state by the processing unit.

6. An information processing apparatus including one or more processing units, wherein

a processing unit of the one or more processing units generates a fist number of test instruction sequences based on the fist number of seed values among a second number of seed values generated based on a seed value held by a managing apparatus for a plurality of information processing apparatuses including the information processing apparatus so as not to overlap with another information processing apparatus, the fist number being same as a number of times of tests conducted by the processing unit and the second number being same as a total number of times of tests conducted by the one or more processing units, and executes the fist number of test instruction sequences.

7. A computer-readable recording medium having stored therein a program for causing a processing unit of one or more processing units included in an information processing apparatus to execute a process comprising:

generating a fist number of test instruction sequences based on the first number of seed values among a second number of seed values generated based on a seed value held by a managing apparatus for a plurality of information processing apparatuses including the information processing apparatus so as not to overlap with another information processing apparatus, the fist number being same as a number of times of tests conducted by the processing unit and the second number being same as a total number of times of tests conducted by the one or more processing units; and

executing the fist number of test instruction sequences.
