模拟一个将回调类型作为参数的对话框 [英] Mocking a dialog box that takes a callback type as argument

问题描述

我为以下类型的对话框创建了模拟设置:

I have created the mock setup for the dialog box of type:

void ShowDialog(string windowName, 
                string parentWindowName,
                Dictionary<string, object> inputFields,
                Action<Dictionary<string, object>> closeCallBack,
                Dictionary<string, object> windowProperties = null);

喜欢:

UIServicemock.Setup(u => u.ShowDialog(It.IsAny<string>(),
                    It.IsAny<string>(),
                    It.IsAny<Dictionary<string, object>>(),
                    It.IsAny<Action<Dictionary<string, object>>>(),
                    It.IsAny<Dictionary<string, object>>())).Callback(ViewName.UnlockScriptPassswordDialog,
                                                                      StudioViewName.MainWindow, 
                                                                      passwordDictionary, ,
                                                                      null);

现在倒数第二个参数中，我不知道如何传递参数，以便对话框可以调用另一个方法.

Now in the second last parameter I don't know how to pass the argument so that the dialog box can call the another method.

我的函数调用是这样的:

My function call is like this:

uiService.ShowDialog(ViewName.UnlockScriptPassswordDialog,
                     StudioViewName.MainWindow,
                     passwordDictionary,
                     this.OnUnlockScriptSetCallBack, null);

这正在调用OnUnlockScriptSetCallBack方法.

推荐答案

如果我理解的不错，您希望对ShowDialog的调用调用该方法的第四个参数.像这样设置:

If I understand you right you want the call to ShowDialog to invoke the fourth parameter to the method. Set it up like this:

UIServicemock.Setup(
                    u =>
                    u.ShowDialog(It.IsAny<string>(), 
                                 It.IsAny<string>(), 
                                 It.IsAny<Dictionary<string, object>>(), 
                                 It.IsAny<Action<Dictionary<string, object>>>(), 
                                 It.IsAny<Dictionary<string, object>>()))
             .Callback<string, 
                       string, 
                       Dictionary<string, object>, 
                       Action<Dictionary<string, object>>, 
                       Dictionary<string, object>>(
                                                   (windowName, 
                                                    parentWindowName, 
                                                    inputFields, 
                                                    closeCallBack, 
                                                    windowProperties) =>
                       closeCallBack(windowProperties /* or whatever dictionary should go here*/)
                                                    );

这样，将传递给ShowDialog的参数发送到指定给Callback方法的Action中.调用ShowDialog时，将调用作为closeCallBack给出的Action<Dictionary<string, object>>.

This way the parameters passed to ShowDialog are sent to the Action given to the Callback method. When ShowDialog is invoked, the Action<Dictionary<string, object>> given as closeCallBack will be invoked.
