mock with rspec

RSpec uses its own mocking framework by default, or you can configure it
explicitly.

Scenarios
  1. passing message expectation
  2. failing message expecation
  3. failing message expectation in pending block (remains pending)
  4. passing message expectation in pending block (fails)
  5. accessing RSpec.configuration.mock_framework.framework_name
passing message expectation
Given
a file named "example_spec.rb" with: 
RSpec.configure do |config|
  config.mock_framework = :rspec
end

describe "mocking with RSpec" do
  it "passes when it should" do
    receiver = double('receiver')
    receiver.should_receive(:message)
    receiver.message
  end
end
When
I run rspec example_spec.rb
Then
the examples should all pass
failing message expecation
Given
a file named "example_spec.rb" with: 
RSpec.configure do |config|
  config.mock_framework = :rspec
end

describe "mocking with RSpec" do
  it "fails when it should" do
    receiver = double('receiver')
    receiver.should_receive(:message)
  end
end
When
I run rspec example_spec.rb
Then
the output should contain "1 example, 1 failure"
failing message expectation in pending block (remains pending)
Given
a file named "example_spec.rb" with: 
RSpec.configure do |config|
  config.mock_framework = :rspec
end

describe "failed message expectation in a pending block" do
  it "is listed as pending" do
    pending do
      receiver = double('receiver')
      receiver.should_receive(:message)
    end
  end
end
When
I run rspec example_spec.rb
Then
the output should contain "1 example, 0 failures, 1 pending"
And
the exit status should be 0
passing message expectation in pending block (fails)
Given
a file named "example_spec.rb" with: 
RSpec.configure do |config|
  config.mock_framework = :rspec
end

describe "passing message expectation in a pending block" do
  it "fails with FIXED" do
    pending do
      receiver = double('receiver')
      receiver.should_receive(:message)
      receiver.message
    end
  end
end
When
I run rspec example_spec.rb
Then
the output should contain "FIXED"
Then
the output should contain "1 example, 1 failure"
And
the exit status should be 1
accessing RSpec.configuration.mock_framework.framework_name
Given
a file named "example_spec.rb" with: 
RSpec.configure do |config|
  config.mock_framework = :rspec
end

describe "RSpec.configuration.mock_framework.framework_name" do
  it "returns :rspec" do
    RSpec.configuration.mock_framework.framework_name.should eq(:rspec)
  end
end
When
I run rspec example_spec.rb
Then
the examples should all pass
