I recently my expo version and my app will now no longer work. I've even tried reverting my app's codebase to a previous commit before I made the changes to my packages. I don't get any errors, instead the app "boots" up and is stuck on the default expo splash screen.

Seems nothing wrong with the component rendering but the test.

You can use getByText query which can be obtained from render.

Answered 2021-Nov-19 at 01:50

Figured out my own issue. I had set global.window = {} in the jest.setup.js file earlier. @testing-library/react-native uses a timers.js file in which they refer to globalObj which they obtain from the following: const globalObj = typeof window === 'undefined' ? global : window;. As window was not technically undefined, globalObj was being set to {} and did not have access to global functionality.

It has been fixed in this merge. So, go ahead and update your version of react-native-modalize

As you may have seen in node_modules/react-native-modalize/lib/utils/devices.js it was related to the reactNativeVersion.

No handler function found for event: "changeText"

ANSWER

Answered 2021-Jul-27 at 18:08

The error occurs because there's no onChangeText callback in your TextInput so there's no handler to call when triggering fireEvent.changeText.

You have to use onChangeText instead.
