Overview

Checks if there is an empty line after example blocks.

Examples:

# bad
RSpec.describe Foo do
  it 'does this' do
  end
  it 'does that' do
  end
end

# good
RSpec.describe Foo do
  it 'does this' do
  end

  it 'does that' do
  end
end

# fair - it's ok to have non-separated one-liners
RSpec.describe Foo do
  it { one }
  it { two }
end

with AllowConsecutiveOneLiners configuration


# rubocop.yml
# RSpec/EmptyLineAfterExample:
#   AllowConsecutiveOneLiners: false

# bad

  it { two }
end
