Make library work with render

[blainekasten]

Currently we are doing nothing with rendered components. chai-enzyme is supporting them nicely. We should find a way to support rendered components.

Does anybody actually use the render method with enzyme? I'm never use it and wonder if it's really necassary to support..

Hi,

actually I do use render for presentational components. There's often cases I want to test child elements and render is a bit easier. Otherwise you need the sub components imported to be able to assert against them.

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

With render:

expect(wrapper.find('svg').toBePresent().

With shallow:

import Svg from '...';

expect(wrapper.find(Svg).toBePresent().

Recently switched to Jest, so we might actually do more snapshots, but still.

That's good to know. Thanks for reporting. I think we'all be in an easier place to support this after #39 is done.

@pascalduez you can use find by name with shallow without a problem.
What you need to do is search for your component name and not your HTML output.

so your With shallow code will be:

expect(wrapper.find('Svg')).toBePresent();

@luizbon Thanks for the feedback, I'll give it another try.

Still, there are (few) cases where I'd like to test against "real" DOM elements, but well.
