`jest.mock()` calls not getting hoisted to the top by `esbuild-runner/jest` about esbuild-runner HOT 3 OPEN

from esbuild-runner.

Can confirm, using esbuild-runner with tests that need to jest.mock imported functions will break things. If you want to quickly reproduce this problem you can setup any test that required mocking imported functions

// something.test.ts

import { importedFunction } from './otherFile'

jest.mock('./otherFile', () => ({
  importedFunction: jest.fn().mockResolvedValue(true),
}))

from esbuild-runner.

any solution for this?

I replaced @swc/jest transformer with esbuild-runner/jest and jest.mock no longer works correctly

some.test.ts

import { myModule } from "@/someDir";
import { myFunction } from "@/myFunction";

jest.mock("@/someDir")

test("test1", () => {
  (myModule as Jest.MockedFunction).mockImplementationOnce(() => Promise.resolve(true));

  myFunction();
  
  expect(myModule).toHaveBeenCalledTimes(1)
 
});

@/myFunction.ts

import { myModule } from "@/someDir";

export function myFunction() {
  // other code...
  myModule();
}
