IOError about simplecov-html

[tansaku]

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

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.
