equivalence class
(foldoc) | equivalence class
An equivalence class is a subset whose elements
are related to each other by an equivalence relation. The
equivalence classes of a set under some relation form a
partition of that set (i.e. any two are either equal or
disjoint and every element of the set is in some class).

equivalence class partitioning
(foldoc) | equivalence class partitioning
equivalence partitioning
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.

equivalence relation
(foldoc) | equivalence relation
A relation R on a set including elements a, b,
c, which is reflexive (a R a), symmetric (a R b => b R a) and
transitive (a R b R c => a R c). An equivalence relation
defines an equivalence class.
See also partial equivalence relation.

observational equivalence
(foldoc) | observational equivalence
Two terms M and N are observationally equivalent iff for all
contexts C[] where C[M] is a valid term, C[N] is also a valid
term with the same value.

partial equivalence relation
(foldoc) | partial equivalence relation
(PER) A relation R on a set S where R is symmetric (x R y => y
R x) and transitive (x R y R z => x R z) and where there may
exist elements in S for which the relation is not defined. A
PER is an equivalence relation on the subset for which it is
defined, i.e. it is also reflexive (x R x).
