International Classification:

G06F 1100

US Classification:

39518314

Abstract:

A software testing system tests software. The software testing system includes a set-up and control system, and one or more test systems connected to the set-up and control system. The set-up and control system includes a user interface for interacting with a user of the software testing system. The set-up and control system stores test data and test configurations. Each test system sets up test cases from the test data and the test configurations stored in the set-up and control system. Each test case inherits attributes from at least one test object within the test system. The inherited attributes facilitates the interaction of the test system with the test cases.

Abstract:

According to some aspects, a method of designing an object based on a three-dimensional model representing a shape of the object is provided. The object may be fabricated from a plurality of materials having one or more known physical properties, wherein the object is designed to exhibit one or more target properties. The method may comprise determining a first composition of the object by providing the three-dimensional model as input to a reducer tree, determining one or more physical properties of the object with the first composition by simulating the object with the first composition, comparing the determined one or more physical properties with the one or more target properties, and determining a second composition of the object based on a result of comparing the determined one or more physical properties with the one or more target properties.
