React Native Update 0.56: npm test is broken (even in new projects). Jest tests do not run.

[janhesters]

I went through all these requirements before I filed this issue. Can't find a fix anywhere.

• Review the documentation: https://facebook.github.io/react-native

• Use the latest React Native release: https://github.com/facebook/react-native/releases

Description

While trying to test my newly created action creators,npm test throws the following error:

> jest

 FAIL  app/actions/logout/logout.test.js
  ● Test suite failed to run

I have googled heavily and can't find a fix. It seems like it has something to do with babel.

Reproducible Demo

It's easy to reproduce (currently). I tried an started a new project using react-native init. Then I just created a random .test.js file and wrote the getting started test of the documentation in it:

function sum(a, b) {
  return a + b;
}

test("adds 1 + 2 to equal 3", () => {
  expect(sum(1, 2)).toBe(3);
});

Next I run 'npm test' and it gives the error above.
