[sblackstone]

Ruby 2.2.3 and 2.3.0

jack: sblackstone$ grep simplecov Gemfile.lock
    simplecov (0.11.1)
      simplecov-html (~> 0.10.0)
    simplecov-html (0.10.0)
  simplecov

But I don't see anything weird about the file that would cause this:

Your problem may be related to this issue: #444

This impacts not only blank lines, but any lines with no executable code on them. Are you merging multiple outputs from simplecov?

[sblackstone]

@ksmurphy no - only have the first line of test_helper.rb as SimpleCov.start 'rails' and everything else is out-of-the-box.

I was just working on another new project and everything was reporting 100% and suddenly within my last couple patches, I started seeing this same bug again in the new project.

[sblackstone]

Update: It was occuring when I forgot to do rvm use 2.3.0.

My system ruby was 2.0.0p481 and it seems to occur when run from there.

[BandanaPandey]

@sblackstone I m also using Ruby 2.3.0 and simplecov 0.11.2.
In my case there is no such problem as end is covered in my simplecov coverage.
I have included following in my Gemfile::
gem "simplecov", "> 0.11.1", :require => false
And, my Gemfile.lock I have ::
simplecov (0.11.2)
simplecov-html (> 0.10.0)
simplecov-html (0.10.0)

[PragTob]

If it occured with some patch level of ruby 2.0.0 it might have been an old simplecov version or a temporary bug in the coverage library. The tests here test plenty of simple cases such as this one so I'll close this out.

Should this error occur again, please let us know :)
