IOError

[tansaku]

I'm getting an odd IOError when running simplecov with feature tests, but not just on specs:

/Users/tansaku/.rvm/gems/ruby-2.2.2/gems/simplecov-html-0.9.0/lib/simplecov-html.rb:21:in `write': not opened for writing (IOError)
    from /Users/tansaku/.rvm/gems/ruby-2.2.2/gems/simplecov-html-0.9.0/lib/simplecov-html.rb:21:in `puts'

    from /Users/tansaku/.rvm/gems/ruby-2.2.2/gems/simplecov-0.9.2/lib/simplecov/defaults.rb:54:in `block in <top (required)>'

Our project has features in a features directory, straight off the root, and specs in a spec directory also straight off root. I get the above running "rspec features" but don't get it when running "rspec" or "rspec spec".

Everything still seems to work in terms of the simplecov output, but gets this error thrown as well ...

I tried upgrading simplecov to the latest version, but same issue:

I also tried moving the feature folder into the spec folder, but again same error

[tansaku]

and I still get it from running a single feature

→ rspec features/login_spec.rb

I can totally imagine that this is due to something weird in our setup - just wondering if anyone else has ever seen the same ...

[colszowka]

This should not be related to the location of your spec/feature folders, it seems simplecov is failing to write it's coverage report. Can you try to delete the ./coverage directory and try again?

[tansaku]

ah, I think we just worked out it is because we are using webmock with the features, which prevents simplecov from outputing the message to the console:

        puts output_message(result)
      end

      def output_message(result)
        "Coverage report generated for #{result.command_name} to #{output_path}. #{result.covered_lines} / #{result.total_lines} LOC (#{result.covered_percent.round(2)}%) covered."
      end

/Users/tansaku/.rvm/gems/ruby-2.0.0-p598/gems/simplecov-html-0.10.0/lib/simplecov-html.rb:25

[colszowka]

That is awkward, webmock should not be related to $stdout output and I have used it on many projects along simplecov without problems. But maybe you are somewhere else closing/redirecting $stdout/STDOUT?

Closing due to inactivity and seemingly/hopefully not related to simplecov itself.
