Abstract: An object of the invention is to provide an environmental test apparatus which can directly set an environmental change rate and hardly causes input errors. Change amount information associated with a total change amount and change rate information associated with a change amount per unit time can be input. A target locus of change can be set by using a change amount/change rate setting method of setting the target locus of change based on a combination of change amount information and change rate information. When setting the target locus of change by the change amount/change rate setting method, input of time information is inhibited.
