NUnit tests not running in parallel

Question

I have a situation where I want to run tests in parallel using NUnit

To do this I use the attributes below

 [Parallelizable(ParallelScope.All)]
 [FixtureLifeCycle(LifeCycle.InstancePerTestCase)]
 [TestFixture] 
 public class MyTestFixture
 {
     [Test]
     public void Test1()
     {

     }
     
     [Test] 
     public void Test2()
     {

     }
  }
}

In my actual scenario I have over 200 tests in a fixture

Watching the test explorer in Visual Studio the tests dont appear to be run in parallel

The same applies when running the tests via NUnit Lite

Is there a way of just running this test fixture via the command line to see if its an issue with the runners?

What am I doing wrong?

Answer 1

If you want to run NUnit tests in parallel, you can use the Parallelizable attribute over the test cases.

NUnit 3 offers a Parallelizable attribute, which can be used to denote which tests can be run in parallel
