Suppressing execution of monitoring measurement program pointed to by inserted branch after threshold number of coverage to reduce instruction testing overhead

A computer readable medium having program code recorded thereon for execution on an information processing device for carrying out a coverage measurement on a test target program, which includes jump instruction codes and non-jump instruction codes, said program code, which includes a coverage measurement control program and a coverage measurement program, causing the information processing device to perform the following method:

• branching to said coverage measurement control program by executing a branch instruction inserted in the test target program;
• determining by said coverage measurement control program whether a number of times an instruction code next to the branch instruction in the test target program was executed has reached a predetermined number of times;
• if the predetermined number of times has not been reached, executing said coverage measurement program to increment the number of times said instruction code was executed;
• and
• if the predetermined number of times has been reached, suppressing both the execution of said coverage measurement program and the incrementing operation.

A information processing device for carrying out a coverage measurement on a test target program, which includes jump instruction codes and non-jump instruction codes, said information processing device comprising:

• a CPU;
• a memory unit;
• a program execution unit for executing the test target program and for transferring control to a coverage measurement control unit when executing a branch instruction inserted in the test target program;
• the coverage measurement control unit for determining whether a number of times an instruction code next to the branch instruction in the test target program was executed has reached a predetermined number of times;
• and
• a coverage measurement unit, activated by the coverage measurement control unit, for incrementing the number of times said instruction code was executed if the predetermined number of times has not been reached,
• wherein said coverage measurement control unit suppresses both the activation of said coverage measurement unit and the incrementing operation if the predetermined number of times has been reached.
