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

csharp

CollectionEquivalentConstraint(IEnumerable other)

Syntax

csharp

Is.EquivalentTo(IEnumerable other)

Examples of Use

csharp

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

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