如何在重试时覆盖NUnit测试结果

Question

I was trying to rerun failed case as below but while marking test case as pass on 2nd run getting below exception at Assert.Pass() step. How to resolve this error?

Exception:

 NUnit.Framework.SuccessException
   at NUnit.Framework.Assert.Pass(String message, Object[] args)
   at NUnit.Framework.Assert.Pass(String message)
   at CodedUI.NUnit2.TestMethod() in NUnit2.cs:line 80
   at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments,   Signature sig, Boolean constructor)
   at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
   at System.Reflection.MethodBase.Invoke(Object obj, Object[] parameters)

Code:

public void TestMethod()
        {

            run++;

            if (run == 1)
            {
                Assert.Fail();
            }
            Console.WriteLine("Rerun..");
            Assert.Pass();

        }

Retrying in clean up as below.

 [TearDown]
    public void cleanup()
    {


        if (TestContext.CurrentContext.Result.Outcome.Status==TestStatus.Failed)
        {
            var type = Type.GetType(TestContext.CurrentContext.Test.ClassName);
            if (type != null)
            {
                var instance = Activator.CreateInstance(type);
                var method = type.GetMethod(TestContext.CurrentContext.Test.MethodName);
                try
                {

                    method.Invoke(instance, null);
                }
                catch(Exception e)
                {

                }
            }
        }
    }

This can't work because NUnit treats every exception, including its own as an error in the TearDown phase. At the time of TearDown, the result of the test is already recorded.
