Pass DialogResult to Callback method in MessageBox.SHow

[Sagar]

Hi,

  I have a MessageBox.Show method, which has a CallBack action associated with it. I want to Pass a Mocked parameter to that action, which would eventually execute the action statements based on Parameter passed.

Action<DialogResult> callback = (result) =>
                    {
                        if (result == DialogResult.Yes)
                        {
                           //Do something here
                        }
                    };
MessageBox.Show("Are you Sure?","Test App",DialogButton.YesNo, DialogImage.Question,callback);

  I tried something like below, but it did not work.

 

Mock.Arrange(() => dialog.Show(Arg.AnyString, Arg.AnyString,DialogButton.YesNo, DialogImage.Question, Arg.IsAny<Action<DialogResult>>())).
           DoInstead((Action<DialogResult> action) =>
           {
             action.Invoke(DialogResult.Yes);
           });

 I want to execute the Original callback, with a mocked DialogResult. 

How can we do that?

 

Thanks in Advance,

Sagar

Hello Sagar,

The delegate passed to DoInstead should have the same signature as the arranged method:

Mock.Arrange(() => dialog.Show(Arg.AnyString, Arg.AnyString,DialogButton.YesNo, DialogImage.Question, Arg.IsAny<Action<DialogResult>>())).
           DoInstead((string message, string title, DialogButton buttons, DialogImage image, Action<DialogResult> action) =>
           {
             action.Invoke(DialogResult.Yes);
           });
