Test report for an almost empty spec file displays '3 passed'

Environment

• vim-rspec version: last available one (cf7eb2f)
• rspec version: 3.2.3
• vim version: NVIM 0.0.0-alpha+201504141749 (compiled Apr 15 2015 11:57:57)

Description

Let's imagine I'm using an almost empty file like so:

class Foo
  def answer
    42
  end
end

describe Foo do
  describe '#answer' do
  end
end

When executing :RunSpec on the file, the result is:

+-- 3 passed --------------------------------------------------
Finished in 0.00015 seconds

Damn !?! 3 tests passed ? where does that come from ?
Let's expand the result report:

++++++++++++++++++++++++++++++
+ PASS: All 0 Specs Pass!
++++++++++++++++++++++++++++++
Finished in 0.00015 seconds

Seems like 3 lines -> 3 passed

The very same thing happen if a add a single test:

class Foo
  def answer
    42
  end
end

describe Foo do
  let (:instance) { Foo.new }
  describe '#answer' do
    it { expect( instance.answer ).to eq 42 }
  end
end

The result being:

+-- 3 passed --------------------------------------------------
Finished in 0.00088 seconds

[Foo]

[#answer]
+ should eq 42

Which expand to:

++++++++++++++++++++++++++++++
+ PASS: All 1 Specs Pass!
++++++++++++++++++++++++++++++
Finished in 0.00088 seconds

[Foo]

[#answer]
+ should eq 42

Could be related to rpsec 3.2.3 output format, then ?
