@opansauce/storybook-test-runner

This NX plugin provides basic support for the new Storybook feature: interaction testing. For now it provides a basic generator to add a new 'e2e' target for your UI libraries. Writing a Play function and running interaction tests in CI will make sure your stories won't become stale and break at runtime.

Getting started

How to use

nx g @opansauce/storybook-test-runner:init my-ui-library

This gives you an additional e2e run target for your project. Use the new target(s) by running:

nx run my-ui-library:e2e

When already having the target my-ui-library:storybook running use:

nx run my-ui-library:test-storybook

Gotcha

When ran in parallel (in CI), the storybook instances need to use a unique port. By default the generator generates it with port 4400, so you have to change it yourself if you have more than one project.

Prerequisites

• You're using Angular
• You're using Storybook by using the @nrwl/angular plugin
• You're using Storybook 6.5.x or higher
• You've setup the interaction testing addon as described here
• You've written a Play function for a story as described here

Roadmap

• add executor and get rid of wait-on and concurrently dependencies
• check for Storybook version in init generator
• add main.js/ts configuration in init generator
• add support for other frameworks than Angular
