React.js Testing Approaches - an overview

This repository aims to show and compare testing approaches you can have with testing React components:

  • Testing the real markup rendered by React using React.findDOMNode
  • Testing through test utilities (find / scry methods from React.addons.TestUtils)
  • Testing with references and the real markup (an improvement to simple testing with the real markup)
  • Testing with React.addons.TestUtils.Simulate
  • Testing using shallow rendering approach

It shows those testing techniques using three components:

  • Greeter component - a simple box with a "Hello, X!" paragraph. (intent: it is a dead easy example to follow)
  • SpecialityOfTheHouse component - a select box with three options to choose (intent: to show interaction with form inputs in tests)
  • InvitationList component - a list of people invited for an event (intent: it is made of more than two components, so it can be shown what to test at the top-level and what not.)

Installation:

You must have io.js or node.js installed.

Then, follow these steps:

git clone git@github.com:arkency/react-testing-approaches.git
cd react-testing-approaches
npm install -g grunt # You may need a root access for this.
npm install

Usage

To run tests, simply run:

grunt test
