mock with flexmock

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

Scenarios
  1. Passing message expectation
  2. Failing message expectation
  3. Failing message expectation in pending example (remains pending)
  4. Passing message expectation in pending example (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 = :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
