snapguidist

Jest Snapshot Testing for React Styleguidist.

Demo

Getting Started

To add snapguidist to your react-styleguidist configuration, follow these steps:

1. install the package using yarn or npm:

yarn add --dev snapguidist

1. enhance the webpack configuration in styleguide.config.js:

+const snapguidist = require('snapguidist');
-module.exports = {
+module.exports = snapguidist({
  components: 'src/components/**/[A-Z]*.js',
  defaultExample: true,
  webpackConfig: {
    module: {
      rules: [
        {
          test: /\.jsx?$/,
          exclude: /node_modules/,
          loader: 'babel-loader',
        },
        {
          test: /\.css$/,
          loader: 'style-loader!css-loader',
        },
      ],
    },
  },
-};
+});

Migrate to v4

In v4, snapshots have been renamed to .sg (as opposed to .snap) to avoid conflicts with Jest, and improve compatibility with create-react-app.

Once upgraded to v4, please run yarn test -u to remove the old snapshots (new ones will be automatically generated on the next run) or the following commands to rename them:

cd .snapguidist/__snapshots/
for old in *.snap; do git mv $old `basename $old .snap`.sg; done

Example

To run the example, install the dependencies and start it:

cd example
yarn install
yarn start

Development

Any contribution to snapguidist is highly appreciated.

Run the following command from the root folder to enable the hot-reload:

yarn build:watch & yarn start
