See more:

I have got the following method in the controller.

C#

public async Task

Where CientId uses the following method in the same controller

C#

public Guid CientId
       {
           get
           {
               Guid clientIdParam;
               Guid.TryParse(Request.QueryString["clientId"], out clientIdParam);

               return clientIdParam;
           }
           set{ }
       }

Now I am trying to write the unit for the above controller method in which I want to mock the line model.ClientId = CientId

Till now I have tried the following test

C#

[Test]
       public async void Edit_edits_booking_form_settings()
       {
           //Arrange
           BookingFormSettingsController controller = Substitute.ForPartsOf

Can anyone please help me moch the line I mentioned .

We can't really see your code, update your question to improve it. However be prepared for disappointment as you don't mock individual lines, you mock whole classes.

There isn't enough here to go one really, but one issue is that you are creating a dependency on Request.QueryString. Since this is MVC, why not add this as part of your model?

Also, another note about that is it looks like the code snippet of ClientId you mentioned is inside your controller. If that is so, you are breaking MVC pattern rules and should move that to your Model.

However, take a look at the following links. You might have to alter your approach to unit testing some in order to mock what you want but this should help at least.
