title: Run NUnit3 tests in parallel from multiple assemblies from console runner
body: <p>I want to be able to run parameterized tests from multiple assemblies in parallel using the NUnit 3 console runner. The key is that I want to be able to run the static initializers in parallel (the slow part of the tests). </p>
  
  <p>I am able to get this to work using the ReSharper 10 test runner in VisualStudio. When I run the same project in the NUnit 3 console runner, the static initializers do not run in parrallel.</p>
  
  <p>I created a simple unit testing solution to reproduce the issue. There are are two projects. Each project has one test class that looks like the class below. I added logging to show that the tests do not run in parallel from the console runner.</p>
  
  <pre><code>[TestFixture]
  public class UnitTest1
  {
      public static IEnumerable Test1Static
      {
          get
          {
  
              Console.WriteLine($"before sleep 1 - {DateTime.Now}");
              Thread.Sleep(12000);
              Console.WriteLine($"after sleep 1 - {DateTime.Now}");
              return new List&lt;bool&gt; { true, true };
          }
      }
  
      [Test, TestCaseSource(nameof(Test1Static))]
      public void TestMethod1(bool tc)
      {
          Assert.IsTrue(tc);
      }
  }
