To quickly and exactly attain a conventionally operated work by automatically operating the manually operated inspection of a test environment in an inspecting work.

A program controlling part 6 checks whether or not activation data pertinent to an inputted test name and test item name are present in an activation data table 8, and reads the activation data when the activation data are present, and executes a program. At that time, an inspecting part 3 checks whether or not the activation data obtained at the execution are the same as the activation data at the previous test in the same specification, and reports the result through an operator outputting part 5 to an operator. After the activation of the program is completed, the input of test data is operated for the activated program. The inspecting part 3 checks whether or not test data pertinent to the test name and the test item in the execution are present in a test data table 7, and reads the test data when the test data are present, and transmits the test data to the program in execution.
