显示自测试单元WPF窗口 [英] Show WPF window from test unit

问题描述

我正在运行测试单元（和学习它们）。很简单，我单位将创建一个列表，并将其传递给我的主窗口。

I am running a test unit (and learning about them). Quite simply, my unit creates a List and passes it to my MainWindow.

我的问题是在我显示（）主窗口单位方法结束。我想让装置没有完成，直到我关闭主窗口。这是我做了什么（见下文） - 这显然是行不通的，感觉就像我在错误的道路上这里。我怎样才能做到这正常吗？

The issue I have is after I show() the main window the unit method ends. I want the unit to not finish until I close the MainWindow. This is what I've done (see below) - it obviously doesn't work and feels like I'm on the wrong path here. How can I do this properly?

    [TestClass]
    public class Logging
    {
        bool continueOn = true;
        [TestMethod]
        public void ShowLogs()
        {
            ShowResults(createLogList());
        }

        private void ShowResults(List<Log> logList)
        {
            MainWindow mw = new MainWindow(logList);
            mw.Closed += mw_Closed;  
            mw.Show();

            while (continueOn)
            { }
        }

        void mw_Closed(object sender, EventArgs e)
        {
            this.continueOn = false;
        }

        private List<Log> createLogList()
        {
            List<Log> listLog = new List<Log>();
            //logic 
            return listLog;            
        }

也许我得把这个到后台辅助线程和监视 - 到说实话我不知道之前我浪费时间，我会很感激一些指导。

Maybe I have to put this onto a background worker thread and monitor that - to be honest I've no idea and before I waste hours, I'd appreciate some guidance.

推荐答案

WPF窗口必须是创建和支持WPF窗口的基础设施（消息泵送）一个线程中。

The WPF Window must be created and shown on a thread which supports the WPF window infrastructure (message pumping).

[TestMethod]
    public void TestMethod1()
    {
        MainWindow window = null;

        // The dispatcher thread
        var t = new Thread(() =>
        {
            window = new MainWindow();

            // Initiates the dispatcher thread shutdown when the window closes
            window.Closed += (s, e) => window.Dispatcher.InvokeShutdown();

            window.Show();

            // Makes the thread support message pumping
            System.Windows.Threading.Dispatcher.Run();
        });

        // Configure the thread
        t.SetApartmentState(ApartmentState.STA);
        t.Start();
        t.Join();
    }

需要注意的是：

Note that:

• 必须创建新的线程中所示的窗口。


• 您必须启动一个调度器（System.Windows.Threading.Dispatcher.Run（））在的ThreadStart返回之前，否则窗口将显示，不久后死去。


• 线程必须配置为在STA公寓运行。
