NUnit Unit tests not showing in Test Explorer with Test Adapter installed

Answer 1

Check whether you have stated [TestFixureSetUp] and [Test]

in the test class

sample:

namespace ClassLibrary1
{
   public class SimpleCalculator
   {
      public Calculator _calculator;
      [TestFixtureSetUp]
      public void initialize()
      {
         _calculator = new Calculator();
      }
      [Test]
      public void DivideTest()
      {
         int a = 10;
         int b = 2;
         int expectedValue = a/b;
         int actualValue = _calculator.Divide(a, b);
         Assert.AreEqual(expectedValue, actualValue, "Functionality not working properly!");
      }
   }   
}
