Mark examples without should as pending

[quaternion]

describe Array do
  it "should size be 0" do
    subject.size == 0
  end
end

This example is passed, but developer forgot call should method. It would be logical to remind him about it and mark the example as pending. I could be wrong, but it seems that the rspec-expectations gem already have the appropriate interfaces.

This has been requested and rejected before. First, not everybody uses rspec-expectations, so this would need to be conditional. Second, the following is perfectly valid:

it "executes with no exception" do
  do_something
end
