How do I reset the window or globalThis for every new test?

[Blankeos]

I can't seem to just use this because it does not work.

describe("a", () => {
   it("b", () => {
      const window = new Window();
      const document = window.document;
      // add globalThis.test here.

     expect(window["test"]).not.toBe(undefined); // does not work. 
   });

   it ("c", () => {
      const window = new Window();
      const document = window.document; 
   });
})

What works is if I use the GlobalRegistrator. The same code would work. BUt the it("c") will inherit the new global variable "test" from the previous it

The easiest way is to just clean up after the test.

One way that will make your code execute within the Window context is to run it in a script inside the Window:

 const window = new Window();
 window.document.write(`<script>window.test = true;</script>`);

What testing tool are you using? Vitest has test isolation that might solve it for you.
