The gem database_cleaner is a beast and may eat some seconds out of your #rspec test suite. By using a simpler approach you can save up some time. More under the cut

I has very #weird wish...

Does anyone tried using #rspec + #jruby for testing plain #java projects? Does this possible ever? Does exists any nice analogues of rspec for java?

In order to stub objects in #cucumber's step definitions like you do with #rspec specs just add

require 'cucumber/rspec/doubles'

to cucumber env.rb file and stub whatever you want :)

Zeus preloads your app and when you run console, generate or rspec tasks it loads much faster - less than a second! More under the cut

I don't like cucumber and scenarios for development, but using it for introducing application features for customers with #capybara produce awesome effect. More under the cut

If you need to confirm or cancel alert dialog in test cases you should do something like this:

# actions.html.slim
= link_to 'EXTERMINATE!!!', planet_path, method: :delete,
                                         data: { confirm: 'Are you sure?' }

#shoulda - is a #gem by #thoughtbot. It provides helpers for your #rspec or unit-tests like this:

# account_spec.rb
it { should belong_to(:user) }
it { should belong_to(:project) }

it { should validate_presence_of(:user) }
it { should validate_presence_of(:project) }
it { should validate_uniqueness_of(:project_id).scoped_to(:user_id) }

Today I had got strange behavior of #rspec while writing tests with #capybara.

This doesn't work:

context 'for unauthorized user' do
  before { visit all_path }
  let!(:tags) { 5.times.map { create(:tag) } }

  it 'should show popular tags' do
    Tag.popular.each do |tag|
      sidebar.should have_link(tag.with_sign)
    end
  end
end

For js: true specs firefox is opening and showing me what happens on the page.

How can I disable it? Is it real?

#rspec #capybara #selenium

I had a problem:

it 'should send confirmation email' do
  review = build(:review)
  ReviewMailer.should_receive(:confirmation).with(review)
  review.save
end

Didn't work and returns undefined method `deliver' for nil:NilClass

Then I found a gist with solution! More under the cut

You can skip group of tests with config!

Add this to spec_helper.rb

config.filter_run_excluding :remote => true

#ruby #rspec

The let blocks are lazy-evaluated and the let! blocks are always evaluated. So simple..

describe(:let) do
  let(:smth) { Smth.create! }
  it { Smth.count.should == 0 }
  it { smth; Smth.count.should == 1 }
end

describe(:let!) do
  let!(:smth) { Smth.create! }
  it { Smth.count.should == 1 }
end

I didn't know about it and was nervous a lot. #ruby #rspec
