Now we arrive at the most interesting (but also hardest) part of UI testing. We usually do this as a team.

First, we need to make a pretty solid Storybook or a set of Storybooks covering most of the scenarios of our UI components. For that we can follow the following structure:

• Write stories for your individual UI components.
• Write another set of stories for integrating the above UI components (you could consider your pages).

For the individual UI components, you may be using a different repository. Then, keep a storybook inside it for those components. Then, in the main app, write stories for integrations.

Testing Plan

Open a new PR (or multiple of them). Then run your Storybook and start reviewing one story at a time. Then you can comment on the PR.
