A simple stateless functional component that we want to test that it renders without propType warnings.
import React, { PropTypes } from 'react'
let VersionListItem = function ({ active, version }) {
return (
React introduced shallow rendering in 0.13. This is an excellent feature that I wish was included earlier in React. It aims to solve the problem of unit testing components without going through a real, or jsdom mocked, DOM. I couldn't find any info online about what lifecycle events it actually fires. So I did some testing of my own. To reproduce, put component.js
and test.js
into a folder and run node test.js
.
TLDR; shallow rendering only invokes the following lifecycle hooks (in order):
getDefaultProps
getInitialState
componentWillMount
stops here until re-rendercomponentWillReceiveProps
shouldComponentUpdate
componentWillUpdate

Majority of search result about unit testing Angular.js apps is about how to do it by using test frameworks that run the tests in a real browser. Even though it's great to be able to test your code in multiple platforms, in my opinion it creates a lot of boilerplate code and makes it hard to run the tests in, for instance a CI-server. |

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.
