Problems running scov for a Rails Engine Source

[krobi64]

I have an engine repo much like mentioned in #221, and like that issue, I am not getting any coverage from my specs:

I attempted to use the solution suggested in the https://gist.github.com/bsodmike/5866873:

# my_engine/spec/spec_helper.rb:

SimpleCov.start 'rails' do
    adapters.delete(:root_filter)
    filters.clear # This will remove the :root_filter that comes via simplecov's defaults
    add_filter do |src|
      !(src.filename =~ /^#{SimpleCov.root}/) unless src.filename =~ /my_engine/
    end
end

However, instead of catching the code in both lib and the app directories of the engine, it instead only captures a few spec files:

Engines are tested in context of a spec/dummy app.

require File.expand_path('../dummy/config/environment.rb',  __FILE__)

Sanity check, did you actually use /my_engine/? Also, normally you would test coverage of spec files. That might be useful in seeing if you have unexecuted tests, but that's about it.

For sanity check, please also try what I suggested in #345 (comment)

After your SimpleCov.start try adding

SimpleCov.at_exit do
  puts Coverage.result.keys
end

Which will output every single file the Ruby stlib Coverage module recorded as being loaded. Hopefully that will help you pinpoint your problem.

Also, forgot to ask,

1. Please share the info from https://github.com/colszowka/simplecov/blob/master/CONTRIBUTING.md
2. Did you look at Create a STANDARD_RESPONSES file for common issues #340 ?
