A tool to count the number of test cases per feature file in order to evenly distribute them then running in parallel

cucumber_test_case_counter.rb

require 'gherkin/parser'
require 'gherkin/pickles/compiler'

@test_case_files = []

@tags_to_ignore = ['@no_parallel', '@wip', '@bug', '@live', '@real', '@mobile', '@site']

all_feature_files = Dir.glob("./**/*.feature")

all_feature_files.each do |feature_file|

  contents = File.read(feature_file)
  parser = Gherkin::Parser.new
  gherkin_document = parser.parse(contents)

  pickles = Gherkin::Pickles::Compiler.new.compile(gherkin_document, feature_file)

  @test_cases_count = pickles.count

  pickles.each do |test_case|
    test_case[:tags].each do |tag|

      if @tags_to_ignore.include? tag[:name]
        @test_cases_count -= 1
        break
      end

    end
  end

  if @test_cases_count > 0
    @test_case_files.push({name: feature_file[2..-1], test_case_count: @test_cases_count})

  end

end


sorted = @test_case_files.sort_by { |k| k[:test_case_count] }.reverse
puts sorted
