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:

Declarative Mixpanel Helper Allows you to declare tracking of onClick event on any type of DOM element.
View gist:7966016
# Helper for tracking mixpanel events, allows for declaritve events. Usage:
# <a href="http://google.com" data-mixpanel="name: 'clicked link'">Google</a>
# <a href="http://cows.com" data-mixpanel="name: 'clicked link', data: { animal: 'cow' }">Cow</a>
# <li data-mixpanel="'clicked list element'">I am not a link!</li>
$(document).on "click", "[data-mixpanel]", (event) ->
options = eval "({" + $(this).attr("data-mixpanel") + "})"
# If event is bound to a link, add delay to ensure event is tracked.
if event.currentTarget.href?
options.data = {} if !options.data?

Rails helper for automatically generating mixpanel tracking for links.
View application.html.erb
<!-- Include Mixpanel and init before this. -->
<!-- Place at the bottom of your layout (ex: app/views/layouts/application.html.erb) -->
<% if content_for :mixpanel %>
<%= javascript_tag(yield :mixpanel) %>
<% end %>
You can’t perform that action at this time.
