minitest

Hopefully a simple question for MiniTest folks.. I have a section of code which I'll condense into an example here: class Foo def initialize(name) @sqs = Aws::SQS::Client.new @id = @sqs.create_queue( queue_name: name ).fetch(:queue_url) @poller = Aws::SQS::QueuePoller.new(@id) end def pick_first @poller.poll(idle_timeout: 60) do |message| process_msg(message) if some_condition(message) end end How can I mock/stub/something-else so that I can feed a message through to be tested by the some_condition() and possibly processed with process_msg() ? I.e. I want to test the @poller.poll(idle_timeout:

I'm using minitest/mock and would like to mock a class. I'm not trying to test the model class itself, but rather trying to test that a service (SomeService) interacts with the model (SomeModel). I came up with this (Hack::ClassDelegate), but I'm not convinced it's a good idea: require 'minitest/autorun' require 'minitest/mock' module Hack class ClassDelegate def self.set_delegate(delegate); @@delegate = delegate; end def self.method_missing(sym, *args, &block) @@delegate.method_missing(sym, *args, &block) end end end class TestClassDelegation < MiniTest::Unit::TestCase class SomeModel < Hack:

I am using Ruby 1.9.2 (ruby -v yields :ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]), and I am trying to get this to work: require 'test/unit' class TestStartup < Test::Unit::TestCase def self.startup puts "startup" end def test1 puts "in test1" end end when I run it, I get Loaded suite test_startup Started in test1 . Finished in 0.000395 seconds. 1 tests, 0 assertions, 0 failures, 0 errors, 0 skips I had a hard time finding documentation on this feature, other than scattered posts here on SO and the like. And yes, I want to use this feature and not setup. TIA Ruby 1.9.x bundles

I use Ruby 2 and Rails 4. I have a folder test/lib , where a few tests are located. But running rake test does not use them. Only the other tests (models, controllers, ...) are running. Where do I have to add the lib folder? I already tried MiniTest::Rails::Testing.default_tasks << 'lib' , but I get NameError Exception: uninitialized constant MiniTest::Rails . I did not add the minitest gem to my Gemfile, because Ruby 2 uses it by default. To use MiniTest::Rails::Testing.default_tasks << 'lib' you need to add the minitest-rails gem to your Gemfile. It is separate from Minitest and adds enables

In Rails 3, when writing functional tests in MiniTest, I got in the habit of testing routes separately from testing my controller actions. I got the idea from the Rails Guide on Testing - Section 9: Testing Routes . However, after upgrading my application to Rails 4 I noticed that the controller action tests themselves have started balking about unknown routes if I don't supply the get|patch|post|delete method with a proper set of params. For example, given routes: # config/routes.rb namespace "api" do namespace "v2", defaults: { format: :json } do resources :users do resources :posts do

The spec library in Minitest is great. I've been able to use it within Rails unit tests no problem. However, Rails functional test inherit from ActionController::TestCase which provides instance variables like @controller in it's setup. Has anyone been using the Minitest::Spec lib for their Rails functional tests? If not, I'm considering creating a small library to do just that. I'm not too keen on rspec, and shoulda is starting to shift it's focus to rspec. It would be nice to have something lightweight and built on tools already provided. james2m Thoughtbot have now split shoulda into
