How to mock for jest?

[amduffy19]

I set up bugsnag for react native according to the docs, but I didn't see anything mentioned about how to mock for jest. I'm getting the following error when I try to run a render test:

console.warn
    Bugsnag.getPlugin() was called before Bugsnag.start()

console.error
    The above error occurred in the <App> component:
        in App
    
    Consider adding an error boundary to your tree to customize error handling behavior.
    Visit https://fb.me/react-error-boundaries to learn more about error boundaries.

TypeError: Cannot read property 'createErrorBoundary' of undefined

I understand that the problem is that Bugsnag.getPlugin() is undefined so it's trying to call createErrorBoundary on undefined, but I don't know how to fix this. Is there a way to mock it?

This fix got me around the jest problem. I'm not sure if this is the best solution or just a workaround.

Hi @amduffy19

There is some discussion around this here with some examples of how you could look to mock bugsnag. Perhaps you could try those and see how you get on.
