Abstract: Disclosed is a washing machine including a transmission. The transmission includes: a variable driving side pulley unit arranged on a side of the output shaft; a variable driven side pulley unit arranged on a side of the input shaft; a driving belt capable of transferring the power between the variable driving side pulley unit and the variable driven side pulley unit; a rotating speed sensing part arranged in the driving side pulley unit and configured to change a pulley diameter with the increase of rotating speed; and a torque cam mechanism arranged between pulley hubs and that form a movable pulley and a fixed pulley of the driven side pulley unit and configured to control speed variation time when the pulley diameter varies in a reversing direction with the increase of the rotating speed via cam grooves and pins.

Abstract: A test support process and a test support program for producing a post-update test pattern when a program under test is updated. When a program under development is updated, a post-update operation description defining details of an operation of a function included in the program under development after the update is acquired. Next, a pre-update operation description having high commonality with the post-update operation description is selected from among pre-update operation descriptions defining details of operations of functions included in the program under development before the update. A pre-update test pattern for an operational test of the selected pre-update operation description is extracted from among pre-update test patterns prepared for operational tests of the program under development before the update. A post-update test pattern for an operational test of the post-update operation description is generated by inheriting at least a portion of the extracted pre-update test pattern.
