This is what I have in my test file:
```js
import "jsdom-worker";
```

Bắt đầu bằng cách chạy src/utils/bg-worker/bg-worker.test.js và đọc src/utils/bg-worker/index.js, tập trung vào việc khởi tạo Worker được hiển thị trong stack trace. Theo dõi cách việc import jsdom-worker khiến node-fetch nhận một URL không tuyệt đối; hoàn thành khi bài kiểm thử Jest chạy mà không có lỗi này và vẫn giữ nguyên hành vi được mong đợi.
