react-defaulting-image

react-defaulting-image

this simple component allows for specifying a default image if the target image can not be loaded.

unit testing strategies

while this is a very simple component, i'm also using this repo to evaluate a few unit testing libraries:

1. jest

• automatically initializes jsdom to be able to test jsx type functionality via react test helpers
• handy auto-mock feature
• jasmine-2 by default
• example

1. mocha

• requires initialization of jsdom
• can use with various assertion libraries, chai is one popular option
• example

1. ava

• requires initialization of jsdom
• runs tests in parallel for performance and isolation win
• enhanced power-assert messages ftw
• example

at this point, ava is my fave based on isolation, concurrency and enhanced-assertion messages
