如何以编程方式运行NUnit

我有一些引用NUnit的程序集,并使用单个测试方法创建一个测试类.我能够获得此程序集的文件系统路径(例如"C:...\test.dll").我想以编程方式使用NUnit来运行此程序集.

到目前为止,我有:

var runner = new SimpleTestRunner();
runner.Load(path);
var result = runner.Run(NullListener.NULL);

但是,调用runner.Load(path)会抛出FileNotFound异常.我可以通过堆栈跟踪看到问题是NUnit在堆栈中调用Assembly.Load(path).如果我将路径更改为"Test,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null",那么我仍会得到相同的错误.

我已经向AppDomain.Current.AssemblyResolve添加了一个事件处理程序,以查看我是否可以手动解析此类型,但我的处理程序永远不会被调用.

让Assembly.Load(...)工作的秘诀是什么？

如果要在控制台模式下打开,请添加nunit-console-runner.dll引用并使用:

NUnit.ConsoleRunner.Runner.Main(new string[]
   {
      System.Reflection.Assembly.GetExecutingAssembly().Location, 
   });

如果你想以gui模式打开,添加nunit-gui-runner.dll引用并使用:

NUnit.Gui.AppEntry.Main(new string[]
   {
      System.Reflection.Assembly.GetExecutingAssembly().Location, 
      "/run"
   });

这是最好的方法,因为您不必指定任何路径.

另一个选项是在Visual Studio调试器输出中集成NUnit runner:

public static void Main()
{
    var assembly = Assembly.GetExecutingAssembly().FullName;
    new TextUI (new DebugTextWriter()).Execute(new[] { assembly, "-wait" });
}

public class DebugTextWriter : StreamWriter
{
    public DebugTextWriter()
        : base(new DebugOutStream(), Encoding.Unicode, 1024)
    {
        this.AutoFlush = true;
    }

    class DebugOutStream : Stream
    {
        public override void Write(byte[] buffer, int offset, int count)
        {
            Debug.Write(Encoding.Unicode.GetString(buffer, offset, count));
        }

        public override bool CanRead { get { return false; } }
        public override bool CanSeek { get { return false; } }
        public override bool CanWrite { get { return true; } }
        public override void Flush() { Debug.Flush(); }
        public override long Length { get { throw new InvalidOperationException(); } }
        public override int Read(byte[] buffer, int offset, int count) { throw new InvalidOperationException(); }
        public override long Seek(long offset, SeekOrigin origin) { throw new InvalidOperationException(); }
        public override void SetLength(long value) { throw new InvalidOperationException(); }
        public override long Position
        {
            get { throw new InvalidOperationException(); }
            set { throw new InvalidOperationException(); }
        }
    };
}
