PropertyConstraint

PropertyConstraint tests for the existence of a named property on an object and then applies a constraint test to the property value.

Constructor

PropertyConstraint(string name, IConstraint baseConstraint)

Syntax

Has.Property(string name)... // followed by further constraint syntax

Examples of Use

Assert.That(someObject, Has.Property("Version").EqualTo("2.0"));
Assert.That(collection, Has.Property("Count").GreaterThan(10));
Assert.That(collection, Has.Count.GreaterThan(10);

Note: As shown in the example, certain common properties are known to NUnit and may be tested using a shorter form. The following properties are supported:

Has.Length...
Has.Count...
Has.Message...
Has.InnerException...
