AnyOf Constraint

AnyOfConstraint tests that a value equals any one of a set of expected values.

Note

Pass expected values as individual parameters, not as an array. To test if a collection contains a specific value, use SomeItemsConstraint instead.

Usage

Is.AnyOf(params object[] expected)

Modifiers

.IgnoreCase
.IgnoreWhiteSpace              // NUnit 4.2+
.Using(IComparer comparer)
.Using(IEqualityComparer comparer)
.Using<T>(IComparer<T> comparer)
.Using<T>(IEqualityComparer<T> comparer)
.Using<T>(Comparison<T> comparer)
.Using<T>(Func<T, T, bool> comparer)
.UsingPropertiesComparer()     // NUnit 4.1+

Examples

[Test]
public void AnyOfConstraint_Examples()
{
    // Value must equal one of the options
    Assert.That(42, Is.AnyOf(0, -1, 42, 100));
    Assert.That("red", Is.AnyOf("red", "green", "blue"));

    // With string comparison modifiers
    Assert.That("RED", Is.AnyOf("red", "green", "blue").IgnoreCase);

    // Negative test
    Assert.That("yellow", Is.Not.AnyOf("red", "green", "blue"));
}

Notes

  1. This is for testing a single value against multiple options.
  2. For testing if a collection contains a value, use Has.Member() or Does.Contain().
  3. All comparison modifiers apply to the equality check between the actual and each expected value.
