Unit Testing and mocking

• Node Version: v8.9.1

I am trying to write a unit test for an action that uses the createClient API. I’ve attempted to intercept the URL that it should be hitting, but to no avail. I am seeking help on the best way to test this by intercepting the request to Contentful. Below is a bit of the code:

actions.js

meow = () => {
  mergedParams = {
    limit: 100,
    'content_type': 'XXXXX',
  }
  return client.getEntries(mergedParams)
    .then((response) => {
      response = JSON.parse(response.stringifySafe())
      dispatch(returnAuthorFetchSuccess(response.items))
    })
    .catch((response) => {
      dispatch(returnAuthorFetchFailure({
        error: 'Unable to fetch XXXXX.',
        response,
      }))
    })
}

test.js

fetchMock.getOnce(`https://cdn.contentful.com:443/spaces/${process.env.REACT_APP_CONTENTFUL_SPACE}/entries?access_token=${process.env.REACT_APP_CONTENTFUL_TOKEN}&content_type=XXXXX`, { value: 'meow' })

    return store.dispatch(actions.meow())
      .then(() => {
        const response = store.getActions()
     })

Does anyone have any insight on the best way to approach this?

Hey @mbenjamin618 , There is different ways of mocking the library depends on your use case. there is a library called contentfaux that maybe can help you.

@matthewfbenjamin any example of this?
