    • PROBLEM TO BE SOLVED: To execute a self-test even during an operation and to improve a fault detection rate. SOLUTION: The self-testing apparatus comprises: an operation element decision part 331 for respectively calculating operation elements 312 and 322 to be used for the operation inside the devices 310 and 320 of a board 301 and non-operation elements on the basis of an operation parameter when operating the board 301 loaded with a reconfigurable device for which functions can be freely changed by configurations; an element allocation decision part 332 for allocating the elements 313, 323, 314 and 324 of a self-test object from the non-operation elements calculated by the operation element decision part 331; and a testing means for testing the elements 313, 323, 314 and 324 by making test signals pass through a test route passing through the element allocated by the element allocation decision part 32.
