Example for Scenario not covered in Examples

Firstly thank you for the great work with the library, its invaluable to so many of us.

So my problem is the following:

I have a method that I call that internally is using SQLCommand with output parameters, the output parameters are then updating the Method parameter that I originally passed in.

I have 3 properties that get set on the input parameters, how do I set those with a Setup command?

This method is an async method just returning Task, with the following signature

Task PerformAction(MethodInputParameter parameters);

parameters before the call would be

parameter.Property1 equals null
parameter.Property2 equals null
parameter.Property3 equals null

after the call

parameter.Property1 equals "value1"
parameter.Property2 equals "value2"
parameter.Property3 equals "value3"

Use the following code:

var mock = new Mock<MethodInputParameter>();
mock.SetupSequence(m => m.Property1)
    .Returns((string)null)
    .Returns("Value2");

await PerformAction(mock.Object);

Having tried implementing the solution above, I couldn't get it to work, more than likely my issues not the responders.

I have subsequently asked a colleague who provided me with this solution, which I have validated works

Action<spParameterWithOutput> action = (parameters) =>
{
    parameters.Output1 = value1; 
    parameters.Output2 = value2; 
    parameters.Output3 = value3;
};

_fixture.Mock.Setup(x => x.Action(
    It.IsAny<spParameterWithOutput>()))
    .Callback(action);
