### Minitest::Mock
|
|
|
|
A simple and clean mock system. There two essential methods at our disposal: expect and verify.
|
|
|
|
require 'minitest/autorun'
|
|
|
|
describe Twipster, "Make every tweet a hipster tweet." do
|
|
before do
|
|
@twitter = Minitest::Mock.new
|
|
@twipster = Twipster.new(@twitter)
|
|
end
|
|
|
|
it "should append a #lolhipster hashtag and update Twitter with our status" do
|
|
tweet = "Skyrim? Too mainstream."
|
|
@twitter.expect :update, true, ["#{tweet} #lolhipster"]
|
|
@twipster.submit(tweet)
|
|
assert @twitter.verify # verifies tweet and hashtag was passed to `@twitter.update`
|
|
end
|
|
end
|
|
|
|
### Reporters
|
|
|
|
gem 'minitest-reporters'
|
|
|
|
require 'minitest/reporters'
|
|
Minitest::Reporters.use! Minitest::Reporters::SpecReporter.new
|
|
|
|
[Default, Spec, Progress, RubyMate, RubyMine, JUnit]
