Support testing with jest and @testing-library/react-native

[itsramiel]

Hi,

I have an app that I am building that requires bottom tabs. I want to use this library as it provides native UI and feel. One issue stopping me from doing that is that I can't seem to be able to interact with the bottom tabs from a jest test setup with @testing-library/react-native.

You can see a guide here from react navigation showing how to do that for the bottom tabs provided by react-navigation. Attempting to something like that with this library is not possible as the rendered react tree has nothing to be interacted with to trigger navigation actions.

This makes it hard to adopt this library into codebases that value tests and validation. I am hoping for a solution

Seems to support testing: https://callstackincubator.github.io/react-native-bottom-tabs/docs/guides/usage-with-react-navigation.html#tabbarbuttontestid

Checking it
