[BUG] ArgumentError within GitHub CI environment: invalid value for Integer(): ""

[etagwerker]

Hi @jmmastey,

Thanks for creating this gem! It has been very useful in estimating how big a Ruby/Rails application really is. I wrote a little bit about it over here: How we estimate the size of a Rails application

I wanted to incorporate it to rails_stats as a way to get both bundler and LOC stats, so I went ahead and submitted: fastruby/rails_stats#21

Unfortunately my test suite fails with this error:

  1) Error:
50
RailsStats::CodeStatistics::#to_s#test_0001_outputs useful stats for a Rails project:
51
ArgumentError: invalid value for Integer(): ""

I see that in your test suite you stub the method that calls tput:

bundler-stats/spec/lib/bundler/stats/printer_spec.rb

Lines 7 to 9 in b55fd31

	def set_term_width(width)
	allow(Kernel).to receive(:"`").and_return(width)
	end

I assume that is a good way to get around that issue in CI.

Would you be interested in a simple patch to this method?

Please let me know.

Thanks,
Ernesto
