How to Moq Setting an Indexed property

Question

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

        

Answer 1

This should work

[Test]
public void MoqUsingSetup()
{
    //arrange
    var index = new Mock();
    index.SetupSet(o => o["Key"] = "Value").Verifiable();
    // act
    index.Object["Key"] = "Value";
    //assert
    index.Verify();
}

You can just treat it like a normal property setter.
