Unity test can't access my code

So I am trying to work on a project using the TDD methodology. But I am getting an error sying that the class I am writing does not exist in the current context.

Here is my folder structure

├── Editor
│ └── Test
│ ├── Tests
│ └── myTest
└── Scripts
└── myScript

Here is myTest

Code (CSharp):

1.         [UnityTest]
2.         public IEnumerator VerifySigilNotTooLong() {
3.             int[] sigil = new int[] { 1, 2, 1 };
4.             int[] swipe = new int[] { 1, 2, 3, 1 };
5.  
6.             Assert.False(VerifySigil.CheckLength(sigil, swipe));
7.         }

and for now, here is myScript

Code (CSharp):

1. public class VerifySigil : MonoBehaviour {
2.     public static bool CheckLength(int[] sigil, int[] swipe) {
3.         return false;
4.     }
5. }

I don't know why I am getting the error

The name 'VerifySigil' does not exist in the current context

Do I have everything in the right folders?
