@wisersolutions/test-js NPM

test-js

Default setup for testing JavaScript/React packages with Jest

Use

Install using

npm install @wisersolutions/test-js

Add a test script to your package.json

{
  "scripts": {
    "test": "test-js"
  }
}

or just run it using npx test-js. This simply launches jest with a default setup tailored for testing packages containing React components - with enzyme and jest-enzyme to automatically include React, and the render functions in the global scope and add enzyme-matchers. Your component tests can now be as simple as:

describe('Component', () => {
  it('renders with defaults', () => {
    expect(shallow(<Component />)).toMatchSnapshot()
  })
})

If you need to customise the configuration, use @wisersolutions/test-js/lib/defaultConfig.js as defaults. If you also need to extend the test framework setup, don't forget to include @wisersolutions/test-js/lib/setup.js from your setup file or simply extend setupFilesAfterEnv config instead of replacing it.

Development

Install

npm install

Develop

After you modify sources, run the following (or set up your IDE to do it for you):

format the code using npm run format
lint it using npm run lint
test it using npm test

and fix the errors, if there are any.

Publish

Publishing is done in two steps:

Create a new version tag and push it to the repository:
```
npm version <patch|minor|major>
git push --follow-tags
```
Build and publish the new version as a npm package:
```
npm publish --access public
```
