Bug

Jest issue #1824

When mounting a stateless function component with enzyme, the component name is preserved when running jest, but not when running jest --coverage. This is causing unit tests to fail when generating coverage that otherwise succeed.

For example, when mounting the component

const Foo = () => <div>Foo</div>

results in

<Foo>
  <div>
    Foo
  </div>
</Foo>

but when generating coverage, it results in

<Component>
  <div>
    Foo
  </div>
</Component>

Reproducing

Unit tests succeed with:

npm test

They fail with:

npm test -- --coverage
