Webusing a two-layer covering array, in which some or all values of a primary covering array represent equivalence classes. A second layer covering array of the equivalence class values is names in the primary array. It is shown that this method can detect certain classes of errors without a conventional test WebApr 12, 2024 · An orthogonal array (OA) is a mathematical object which may be used as the design matrix of a factorial experiment [ 53 ]. Also, the design matrix of an efficient factorial experiment is an OA or includes an OA as a subset. CT began with the use of OAs to test software-based systems.

WebMar 1, 2024 · The Covering Array Number (CAN) is the minimum N such that for fixed k, v, and t a CA exists. The CAN is denoted by CAN (t,k,v). The construction of CA with N=CAN (t,k,v) is a challenging problem whether we use mathematical structures or … WebJan 1, 2015 · A covering array \(t-\text{ CA }(n,k,g)\), of size n, strength t, degree k, and order g, is a \(k\times n\) array on g symbols such that every \(t\times n\) subarray contains every \(t\times 1\) column on g symbols at least once. Covering arrays have been studied for their applications on software testing, hardware testing, drug screening, and in areas where … bubblefish robot
