1. A method for determining user interface (UI) coverage, comprising: utilizing a computing resource with a number of personnel interfaces for: populating cells of a matrix with a plurality of UI configuration parameters to determine a total number of testable UI configurations; reducing a number of the cells of the matrix by combining at least two UI configuration parameters to determine a reduced number of UI configurations to test; executing a number of predetermined tests, wherein test results depend on input of the reduced number of UI configurations; and determining the UI coverage based upon the test results.
