My unit test is always pending

First time attempting to use unit tests. I'm going to go through my steps:

1. Right clicked solution of my project I want to test in visual studio and clicked 'new project'. Then I selected Test > Test Project.

2. This gave me another project under my solution with a Test.cs file. I added the following to it:

   namespace TestProject1    
   {
   [TestClass] 
   public class MainTest
   {
   
       Project1.MainWindow mw = new Project1.MainWindow(); //not used in test yet
   
       [TestMethod]
       public void MakeDoubleDate_Test()
       {
           string validMpacString = "1998,265/302010"; //When converted, should be 36060.430902777778
           string nonValidString1 = "nope,700/807060";
           string nonValidString2 = "thisDoesn't work";
   
           double validDouble = Project1.ConversionsUnit.MakeDoubleDate(validMpacString);
           double nonValidDouble1 = Project1.ConversionsUnit.MakeDoubleDate(nonValidString1);
           double nonValidDouble2 = Project1.ConversionsUnit.MakeDoubleDate(nonValidString2);
   
           Assert.AreEqual(validDouble, 36060.430902777778);
           Assert.AreEqual(nonValidDouble1, DateTime.Now.ToOADate());
           Assert.AreEqual(nonValidDouble2, DateTime.Now.ToOADate());
       }
   }
   
   

   }

My original project is called Project1. In my test project, I added a reference to Project1.

Now, my test shows up in the test view, but trying to run it it just is stuck on pending forever. I tried another person's project w/ tests and it did the same thing. Not sure what I need to do. Haven't had any luck snooping around google.

Edit: Here's some Debug output when I try running it:

Which continues until I exit out of visual studio.
