            Jest and Async Storage in React Native
            Asked 2020-Dec-08 at 04:13

            I am learning TDD and trying to implement async storage tests by following the guides from https://react-native-async-storage.github.io/async-storage/docs/advanced/jest/ I have followed the installation and currently trying to mock async storage in my first test.

            I created a simple test.

            I think you have misunderstood the documentation. asyncOperationOnAsyncStorage is just an example method that is defined in the documentation, you will have to replace asyncOperationOnAsyncStorage with the method that you have some async storage operation.

            So essentially asyncOperationOnAsyncStorage will be the method that will contain the async storage logic.

            AppNavigator shouldn't return null because this makes the mock useless to test App.

            In order to receive a ref, AppNavigator should be class or forwardRef component. createAppContainer arguments can be optionally represented in element hierarchy in order to be testable by a snapshot:

            I think what you're trying to do is to limit the initial text passed in props to the maxLength of characters passed.

            Async testing React Navigation 5 in Jest: NavigationContainer causes console error
            Asked 2020-May-11 at 13:20

            I'm using react-native-testing-library and after upgrading react-navigation from 4 to 5, I followed these instructions: https://callstack.github.io/react-native-testing-library/docs/react-navigation to upgrade most of my test suite.

            So far so good. The crux here is basically to wrap your tests in a NavigationContainer so my components have access to those hooks that previously came from react-navigation-hooks.

            This works fine when my tests are synchronous, but as soon as I add the async keyword to the test function, I get the following warning:

            Jest: unexpected token export with react-navigation
            Asked 2020-Mar-04 at 14:29

            After spending two days in researching, I've finally run out of ideas.

            The problem is a component that uses withNavigation from React-Navigation.

            When I run Jest, it complains about an unexpected token export (React-Navigation), pointing withNavigation.

            Since there is the same problem with other third-party libraries (such as Native Base), I concluded there must be a problem with transformIgnorePatterns. For example, I tried this solution among sooo many others, that are more or less similar. I also tried to adjust babel.config, as suggested in another post at GitHub. Nothing works! Maybe someone has any idea? Please not that I use TypeScript.
