PROGRAM TEST DEVICE

PROBLEM TO BE SOLVED: To provide a program test device capable of reducing a time required for preparing information relating to state transition of a verification object program, and starting a test of the verification object program more quickly.SOLUTION: An operation event acquisition unit 14 acquires an operation event indicating details of an operation by an operator. A screen transition detection unit 24 detects that an operation screen displayed by a display unit 22 has made transition by an operation of a verification object program based on the operation event. A screen data acquisition unit 26 acquires screen data of an operation screen after the transition. A state transition information preparation unit 30 prepares state transition information associating the operation event, an operation screen before the transition, and an operation screen at a transition destination when the operation event has occurred with one another.
