title: How to use Parallelizable in NUnit?
body: <p>How can I use Parallelizable attribute to run tests nonparallel? I'm using <code>Selenium</code> + <code>NUnit 3.7.1</code>. I put <code>[Parallelizable(0)]</code> in my <code>TestBase</code> class, but still tests running parallel. Tests fails on Run All but if I run one by one they pass. </p>
  
  <p>My <code>TestBase.cs</code></p>
  
  <pre><code>[TestFixture]
  [Parallelizable(0)]
  public class TestBase
  {
      [TestFixtureSetUp]
      public static void Initialize()
      {
          Browser.Initialize();
      }
  }
  </code></pre>
  
  <p>My tests:</p>
  
  <pre><code>class  Tests: TestBase
  {
  
      [Test]
      public void TestA()
      {
        // test code here
      }
  
      [Test]
      public void TestB()
      {
         // test code here
      }
  
  }
  </code></pre>
