Wisper::MiniTest

MiniTest assertions/expectations and stubbing for Wisper. Based on @krisleech work and his own wisper-rspec gem.

Installation

gem 'wisper-minitest', require: false

Usage

Broadcast assertion

In test_helper

require 'wisper/minitest/assertions'

In your tests:

assert_broadcast(:an_event) { publisher.execute }

This will match both broadcast(:an_event) and broadcast(:an_event, :arg_1).

# with optional arguments
assert_broadcast(:another_event, :arg1, :arg2) { publisher.execute }

With event arguments, it matches only if the event is broadcast with those arguments. This assertion matches broadcast(:another_event, :arg1, :arg2) but not broadcast(:another_event).

Todo

The wisper-rspec gem is not fully ported yet. Here's what's missing:

• Convert broadcast expectation to assert_broadcast assertion
• Add a refute_broadcast assertion
• Make those available as Minitest expectations too
• Document or implement a way to assert that a listener is receiving events
• Port publisher stub feature
