Test design assistance device, test design assistance method, and computer-readable medium

A test design assistance method causing a computer to execute a process, the process comprising:

• generating path information indicating a transition path based on a transition event with a designated state as a starting point in a state transition diagram in which the transition event transitioning from one state to the same or another state is described;
• setting each transition event included in the path information to a factor and sets a type of the transition event to a level;
• allocating sets of the set factors and levels to a matrix having a designated size;
• extracting a combination that does not appear in any row of the matrix to which the sets are allocated, among combinations pertaining to all levels between any plurality of factors included within a designated distance in the path information;
• and
• adding a row including the extracted combination to the matrix to thereby generate a test matrix.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• generating path information indicating a transition path based on a transition event with a designated state as a starting point in a state transition diagram in which the transition event transitioning from one state to the same or another state is described;
• setting each transition event included in the path information to a factor and sets a type of the transition event to a level;
• allocating sets of the set factors and levels to a matrix having a designated size;
• extracting a combination that does not appear in any row of the matrix to which the sets are allocated, among combinations pertaining to all levels between any plurality of factors included within a designated distance in the path information;
