How to write story that updates component?

I would like to simply see if component behaves correctly when it receives new props. Or even if it receives same props so it’s possible to check that there is no logical error with shouldComponentUpdate. Is there some way for that?

Perhaps an idea for addon? Although I see tiny problem with addons that they cannot be combined, so if such functionality comes with addon, I could not use info addon for that story.

componentWillUpdate is not called in the initial render. We always do the initial rendering for all stories. That to prevent to state related issues.

So, if you wanna test componentWillUpdate you need to run render your component inside a wrapper component.

That wrapper component may have a some kind of a button which re-render your original component. Then it’ll call the componentWillUpdate.

Ah, sorry, I wanted to try it first before responding, but never got a chance with it (more priority stuff). But what you said makes total sense.
