title: dotnet test command not finding any test to execute in nUnit
body: <p>I am using 3.12.0 version of <strong>nunit</strong> and 3.15.1 version of nunit test adapter.
  I have created a project in .net and added a simple code in class to run tests.
  From <strong>Test->Windows->Test Explorer</strong>, I am able to view and run test cases but when I try to run from command line, It is not running anything and not giving any error also.</p>
  
  <p>I am not sure what I am missing. Can anyone suggest what could be the possible reason for this?</p>

  <p>My code looks like this</p>
  
  <pre><code>using NUnit.Framework;
  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  
  namespace SpecFlow.API.Test
  {
      public class Class1
      {
          [SetUp]
          public void setupclass()
          {
             // Console.ReadLine();
          }
  
          [Test]
          public void setuptest()
          {
              Assert.Fail("ERROR");
              Console.ReadLine();
          }
  
          [TearDown]
          public void tearDown()
          {
              Assert.Fail("ERROR");
          }
      }
  }
  ```
  
  </code></pre>
