[Jest] ReferenceError with inlineRequire: true

[grabbou]

Possibly related to #3999 @cpojer comments.

After upgrading from 0.14.2 to 0.17 and using react-native preprocessor.js - with default value set to true:

ReferenceError: /src/auth/newPasswordForm.js: _immutable is not defined
        at Object.<anonymous> (src/auth/newPasswordForm.js:3:30)

that:

import {Map} from 'immutable'

is simply striped out from transformed code (the first line in the file). Setting it to false makes tests green again.

Funny fact is that it's only affected by the jest. When running normally with packager - all goes smoothly.

Hey grabbou, thanks for reporting this issue!

React Native, as you've probably heard, is getting really popular and truth is we're getting a bit overwhelmed by the activity surrounding it. There are just too many issues for us to manage properly.

• If you don't know how to do something or something is not working as you expect but not sure it's a bug, please ask on StackOverflow with the tag react-native or for more real time interactions, ask on Discord in the #react-native channel.
• If this is a feature request or a bug that you would like to be fixed, please report it on Product Pains. It has a ranking feature that lets us focus on the most important issues the community is experiencing.
• We welcome clear issues and PRs that are ready for in-depth discussion. Please provide screenshots where appropriate and always mention the version of React Native you're using. Thank you for your contributions!

I'm having a similar issue, replacing import ... from ... with require() works around the error. Perhaps somehow Babel is not setup correctly while testing?

Same, for jest 0.9.0-fb2 and react-native 0.19.
Probably, using require or setting inlineRequires: false gets work done, but any update on this issue?

UPD: same for RN 0.21.0-rc and 0.20.0 as well...

btw. I'll be recommending to use babel-jest together with babel-preset-react-native but I haven't had enough time to rewrite the documentation for this yet, unfortunately.

Thank you for your patience. We launched Jest 14.0 with experimental react-native support:

Please feel free to create new issues after trying out the new integration if any issues remain.
