Abstract: The present disclosure discloses a light-transmittance device and a use method, and belongs to the technical field of manufacturing of rotary equipment. The light-transmittance device includes cylinder sections, a two-column vertical lathe, and a vertical lathe platform; T-shaped supporting fixtures are arranged inside the cylinder sections; light-transmittance tools are arranged at center positions of the cylinder sections; two ends of the cylinder sections are provided with rolling ring base plates which are paired and mounted with the cylinder sections; a roller frame is arranged on a lower side of each group of cylinder section; furthermore, the rolling frames are slidably connected with a rigid rail; a theodolite is arranged on one side close to the cylinder sections; and a triangular bracket and a light-transmittance platform are arranged on a lower side of a shell of the theodolite.

Abstract: Generating pseudorandom test items for software testing of an Application Under Test (AUT) is provided. In one example, a method comprises selecting an oracle of one or more oracles within a test provider directory structure, the oracle defining one or more logical paths each comprising one or more test conditions and an expected result. A pseudorandom test item having an initial state of empty is generated, and a logical path of the one or more logical paths is selected. The one or more test conditions of the logical path are translated into a constraint. Based on the constraint, a pseudorandom test input is generated and stored in the pseudorandom test item in association with the expected result corresponding to the logical path.
