How do you get a fresh copy of a module with module-level state in each test?

beforeEach(() => vi.resetModules());
test("...", async () => {
  const { counter } = await import("./counter");
});

• ✓Correct answer: Reset the module registry and import the module dynamically inside the test (Jest: jest.resetModules/isolateModules)
• 2Call delete require.cache in ESM
• 3It's impossible - modules are singletons
