I just published Imitation, a new Node package that helps with testing React components (especially those using CSS modules).
The most common use case is simply for mocking out image/css
For example, say you have a component:
If you were to simply use something like Enzyme then it would fail when trying to
require the css and image files.
That's where Imitation comes in. It hooks into the default
injects a simple mock for images and css (images resolve to their own path and css resolves to a Proxy object where all custom
properties resolve to just their name).
Imitation also has some methods for mocking URLs (for testing Redux Actions, etc) but I'll let you check them out in the README.
