A condition determination device includes an acquiring unit, a specifying unit, a classifying unit, and a condition determining unit. The acquiring unit acquires a total execution history, which is an execution count for each component included in a program, when a test is performed by supplying a plurality of input data to a target device which executes the program. The specifying unit specifies a shortage component of which the execution count indicated by the total execution history does not satisfy test criteria among components included in the program. The classifying unit classifies each of the input data into first data, which causes the target device to execute the shortage component, and second data, which does not cause the target device to execute the shortage component. The condition determining unit determines a condition of input data having a common characteristic with the first data.
