Idiomatic React Testing Patterns

Idiomatic React Testing Patterns

Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you write readable, flexible tests for the type of component you are testing.

Setup

I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a beforeEach. This will help ensure tests are isolated and make things a bit easier to reason about. I use a pattern that gives great defaults for each test example but allows every example to override props when needed:

example component
// all of our components are in their own directories with local css
// so we use index.js (node resolution paradigm) so we can write:
// `import Button from 'components/button'`
// rather than:
// `import Button from 'components/button/button'`
//
// eg. dir structure
// /components/button
// /components/button/index.js
// /components/button/button.js
Security - the elephant in the room. Everyone agrees that it is very important but few takes it seriously. We at RisingStack want you to do it right - this is why we have put together this checklist to help you guide through the must have security checks before your application is enabled to thousands of users/customers.
Most of these items are general and applies to all languages and frameworks not just Node.js - however some of the tools presented are Node.js specific. You should also check our introductory Node.js security blogpost.

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

JS: AngularJS Directive Attribute Binding Explanation

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

  1. Raw Attribute Strings

    <div my-directive="some string" another-param="another string"></div>
