CollectionEquivalent Constraint

CollectionEquivalentConstraint tests that two IEnumerables are equivalent - that they contain the same items, in any order. If the actual value passed does not implement IEnumerable an exception is thrown.

Constructor

CollectionEquivalentConstraint(IEnumerable other)

Syntax

Is.EquivalentTo(IEnumerable other)

Examples of Use

int[] iarray = new int[] { 1, 2, 3 };
string[] sarray = new string[] { "a", "b", "c" };
Assert.That(new string[] { "c", "a", "b" }, Is.EquivalentTo(sarray));
Assert.That(new int[] { 1, 2, 2 }, Is.Not.EquivalentTo(iarray));

Notes

1. To compare items in order, use Is.EqualTo().
