Property Constraint
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);
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...
