What (who) is equivalence partitioning - definition
Equivalence partitioning
Equivalence partitioning or equivalence class partitioning (ECP) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In principle, test cases are designed to cover each partition at least once.
equivalence class partitioning
<testing> A software testing technique that involves
identifying a small set of representative input values that
invoke as many different input conditions as possible.
For example, for binary search the following partitions
exist: inputs that do or do not conform to pre-conditions,
Inputs where the key element is or is not a member of the
array. One can combine these into finer partitions. One can
also pick specific conditions of the array, e.g. a single
value, even or odd number of elements. One should look at
boundary conditions, e.g. inputs where the key element is
the first or last element in the array.
