Public Instance Methods

extract_regex(line) click to toggle source

determine if the line in a cucumber feature file is a feature and return the kind, and the regexp associated with the feature. Note that the regexp is returened as a string.

# File lib/cucumber-slices.rb, line 12
def extract_regex line
  if line =~ /^(Then|Given|When|And)[ (]\/(.+)\/[^\/]+$/
    return [$1, $2]
  else
    return nil
  end
end

extract_steps(file) click to toggle source

scan step file for steps. return an array of the steps in the Command struct

# File lib/cucumber-slices.rb, line 22
def extract_steps file
  in_cmd_block = false
  cmd = nil
  code = []
  @steps = []
    file.each do |line|
      if line =~ /^end/
        in_cmd_block = false
        command = Command.new
        command.command, command.regex = extract_regex cmd
        command.code = code
        @steps << command
        code = []
      elsif line =~ /^(Given|When|Then|And)/
        in_cmd_block = true
        cmd = line
      else
        code << line if in_cmd_block
      end
    end
end

splice_features(feature_file, lines=nil) click to toggle source

match steps to features and output an array of lines that can be displayed

# File lib/cucumber-slices.rb, line 46
def splice_features(feature_file, lines=nil)
    splice = []
    count = 0
    feature_file.each do |line|
      count = count + 1
      if !lines or lines.include?(count)
        splice << "#{count.to_s} #{line}"
        if line =~ /^([ \t]+)(Given|When|Then|And) (.+)/
          indent = $1
          cmd = $2
          code = $3
          @steps.each do |step|
            if code =~ Regexp.new(step.regex)
              step.code.each do |l|
                splice << "#{indent}#{l}"
              end
            end
          end
        end
