Open handles when testing with jest

[atheck]

Hi, when I run component tests with jest there are open handles which keep jest from exiting. Running jest with --detectOpenHandles I get the following output:

> 5 | import { Provider } from "react-native-paper";

• react-native-paper: 4.12.4
• react-native-vector-icons: 9.2.0
• react-native: 0.68.3

I'm using the "react-native" jest preset. I think there is nothing special in my jest setup.

Can someone help me with that?

Couldn't find version numbers for the following packages in the issue:

• react-native-paper
• react-native-vector-icons

Can you update the issue to include version numbers for those packages? The version numbers must match the format 1.2.3.

The versions mentioned in the issue for the following packages differ from the latest versions on npm:

• react-native (found: 0.68.3, latest: 0.69.4)

Can you verify that the issue still exists after upgrading to the latest versions of these packages?

Hey! Thanks for opening the issue. The issue doesn't seem to contain a link to a repro (a snack.expo.dev link or link to a GitHub repo under your username).

Can you provide a minimal repro which demonstrates the issue? A repro will help us debug the issue faster. Please try to keep the repro as small as possible and make sure that we can run it without additional setup.

Have you mocked the Animated helper? Ex: https://github.com/callstack/react-native-testing-library/blob/7dd403b2ea76df40c04b22fda91773b95d4454c7/examples/reactnavigation/jest-setup.js it helps with some cases of open handles

Yes I'm already mocking the NativeAnimatedHelper.

Thank you for your reply @thymikee.
