Enzyme Theme Utils

npm install enzyme-theme-utils

Motivation

Testing React components that need to be wrapped in a ThemeProvider is a pain in the butt. So after lots of trial-and-error programming I created this module to rectify this. Essentially what it does is renders the ThemeProvider and it's children inside a wrapper. Then it adds context to the wrapped ThemeProvider. Then it extracts the children and adds the context from the ThemeProvider to the child and mounts it.

Usage

mountWithTheme

import React from 'react'
import PropTypes from 'prop-types'
import { mountWithTheme } from 'enzyme-theme-utils'

const someTheme = {
  colors: {
    red: 'red',
    yellow: 'yellow'
  }
}

describe('some themed component', () => {

  it('can be mounted', () => {
    const test = mountWithTheme(
      <SomeComponent/>,
      someTheme
    )

    // Assertions

  })
})
