Jest did not exit one second after the test run has completed.

I'm getting this message every time i'm using any libraries that depend on promises.

🐛 Bug Report

Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with --detectOpenHandles to troubleshoot this issue.

To Reproduce

I have a function that need to make a request to external api, and in the same method just save in the database without waiting for a response.

I don't want to wait until the saving process is done, but i'm forced to change the behaviour of my application to get it tested through jest., or i need to close the connection, stop the server for my code to work.

Expected behavior

Excecpted jest to stop and return to my console.

line49 and line50

test("it should create new order", async () => {
  const response = await server.inject({
    method: "POST",
    url: "/api/orders",
    payload: JSON.stringify({
      customer: {
        email: "asd@gmail.com",
        phone: "20 51 75 95",
        city: "Aarhus",
        zip: "8000",
        first_name: "jamal",
        last_name: "soueidan"
      },
      properties: [
        {
          name: "custom engraving",
          value: "Happy Birthday Mom!"
        }
      ]
    })
  });

  expect(response.statusCode).toBe(200);
});

I had to make those changes to get jest working with my api server and mongodb. https://github.com/jamalsoueidan/giv-et-tilbud/commit/d8f326b6294f88d1f12136042d4adfdc83328201

For those experiencing this when working with Firebase, you likely need to call testEnv.cleanup();

let testEnv;

beforeAll(async () => {
  // Silence expected rules rejections from Firestore SDK. Unexpected rejections
  // will still bubble up and will be thrown as an error (failing the tests).
  setLogLevel("error");
  testEnv = await initializeTestEnvironment({
    projectId: projectId,
    firestore: {
      rules: readFileSync("firestore.rules", "utf8"),
      host: "127.0.0.1",
      port: 8080,
    },
  });
});

afterAll(async () => {
    await testEnv.cleanup();
})
