created with node 10.8.3 npm 6.4.1 yarn 1.12.3
Build it:
yarn install && yarn run buildfire up 3 different terminals and run:
yarn run test- this wil start the jest + enzyme test to run through the test cases, I do not normally test components to death, but normally implement end-end testing to catch logic & implementation errors.
- i believe in sanity and informed choice. Running snapshot testing of components can to a very large degree cover most test cases (that is if you create you components atomically)
- Normally i'd implement a Visual Diff engine on top of Casper or another Headless browser to catch all Style regression and errors.
- too see how this works in practice change the padding in WidgetWrapper.css to 0 while tests are running
yarn run storybook- this will run and launch storybook - my prefered way of working with components as I'm a fan of Storybook Driven Development
- In order to demonstrate how that works, i've exploded the component in a a few more subcomponents that is strictly necessary, and i've added a generic button you can examine as well
yarn run start- This will run the application as an isomorphic SSR application and launch 2 servers 1 is the basic server of the client assets (your typical serve -s server) 2 the other runs an express app that hydrates the react app in order to support the usecase of working without javascript
