@Beta @GwtCompatible public final class EquivalenceTester<T> extends java.lang.Object
Equivalence relationships between groups of objects.
To use, create a new EquivalenceTester and add equivalence groups
where each group contains objects that are supposed to be equal to each
other. Objects of different groups are expected to be unequal. For example:
EquivalenceTester.of(someStringEquivalence)
.addEquivalenceGroup("hello", "h" + "ello")
.addEquivalenceGroup("world", "wor" + "ld")
.test();
Note that testing Object.equals(Object) is more simply done using
the EqualsTester. It includes an extra test against an instance of an
arbitrary class without having to explicitly add another equivalence group.

EquivalenceTester<T> |
addEquivalenceGroup(java.lang.Iterable<T> group) |
EquivalenceTester<T> |
addEquivalenceGroup(T first,
T... rest)
Adds a group of objects that are supposed to be equivalent to each other
and not equivalent to objects in any other equivalence group added to this
tester.
