是否可以使用最小起订量模拟 System.Windows.Window

Is it possible to mock System.Windows.Window using moq

我有一个 AsyncDelegateCommand 接受 Window 的参数,我尝试模拟 class 但我以异常结束 The calling thread must be STA, because many UI components require this.

删除门命令:

private AsyncDelegateCommand<Window> okCommand;

public AsyncDelegateCommand<Window> OkCommand => this.okCommand ?? (this.okCommand = new AsyncDelegateCommand<Window>(this.OkAsync));

方法实现:

private async Task OkAsync(Window win)
{
   //Logic
}

我目前模拟它的方式是使用:

private Mock<Window> mockWindow;
this.mockWindow = new Mock<Window>();
await this.sut.OkCommand.ExecuteAsync(this.mockWindow.Object);

在调试对象时,我可以看到对象值是异常 this.mock Window.Object' threw an exception of type 'System.Reflection.TargetInvocationException

如果不可能,是否有其他方法可以实现这一目标?

我能够按照评论 [Apartment(ApartmentState.STA)] 对我的测试方法

添加属性的建议来解决问题

例如:

[Test]
[Apartment(ApartmentState.STA)]
public async Task TestMethod()
{
    //Logic
}
