I'm trying to use mock to verify that an index property has been set. Here's a moq-able object with an index:
public class Index
{
IDictionary<object ,object> _backingField
= new Dictionary<object, object>();
public virtual object this[object key]
{
get { return _backingField[key]; }
set { _backingField[key] = value; }
}
}
First, tried using Setup()
:
[Test]
public void MoqUsingSetup()
{
//arrange
var index = new Mock<Index>();
index.Setup(o => o["Key"]).Verifiable();
// act
index.Object["Key"] = "Value";
//assert
index.Verify();
}
...which fails - it must be verifying against get{}
So, I tried using SetupSet()
:
[Test]
public void MoqUsingSetupSet()
{
//arrange
var index = new Mock<Index>();
index.SetupSet(o => o["Key"]).Verifiable();
}
... which gives a runtime exception:
System.ArgumentException : Expression is not a property access: o => o["Key"]
at Moq.ExpressionExtensions.ToPropertyInfo(LambdaExpression expression)
at Moq.Mock.SetupSet(Mock mock, Expression`1 expression)
at Moq.MockExtensions.SetupSet(Mock`1 mock, Expression`1 expression)
What's the correct way to accomplish this?
