SomeItems Constraint

SomeItemsConstraint applies a constraint to each item in an IEnumerable, succeeding if at least one of them succeeds. An exception is thrown if the actual value passed does not implement IEnumerable.

This constraint will also cover Contains functionality. See examples below.

Examples of Use

csharp

int[] iarray = new int[] { 1, 2, 3 };
string[] sarray = new string[] { "a", "b", "c" };
Assert.That(iarray, Has.Some.GreaterThan(2));
Assert.That(sarray, Has.Some.Length.EqualTo(1));

Note

Has.Member(), Contains.Item() and Does.Contain() work the same as Has.Some.EqualTo().
