Overview

Checks if there is an empty line after let blocks.

Examples:

# bad
RSpec.describe Foo do
  let(:something) { 'something' }
  let(:another_thing) do
  end
  let(:something_else) do
  end
  let(:last_thing) { 'last thing' }
end

# good
RSpec.describe Foo do
  let(:something) { 'something' }
  let(:another_thing) do
  end

  let(:something_else) do
  end

  let(:last_thing) { 'last thing' }
end

# good - it's ok to have non-separated without do/end blocks
RSpec.describe Foo do
  let(:something) { 'something' }
  let(:last_thing) { 'last thing' }
end
