mock with flexmock

Configure RSpec to use flexmock as shown in the scenarios below.

Scenarios
Passing message expectation
Given
a file named "example_spec.rb" with:
RSpec.configure do |config|
  config.mock_framework = :flexmock
end

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

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

RSpec.describe "failed message expectation in a pending example" do
  it "is listed as pending" do
    pending
    receiver = flexmock('receiver')
    receiver.should_receive(:message).once
  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 example (fails)
Given
a file named "example_spec.rb" with:
RSpec.configure do |config|
  config.mock_framework = :flexmock
end

RSpec.describe "passing message expectation in a pending example" do
  it "fails with FIXED" do
    pending
    receiver = flexmock('receiver')
    receiver.should_receive(:message).once
    receiver.message
  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 = :flexmock
end

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