[Cucumber] 如何用 rakefile 重跑 Cucumber Fail 的 Features ???

Use --format rerun --out rerun.txt to write out failing features. You can rerun them with cucumber @rerun.txt. 

• :run 用來執行任務
• :rerun 用來重跑任務

require 'rubygems'
require 'cucumber'
require 'cucumber/rake/task'

namespace :test do

    desc 'ExecuteTestCase'
    task :execute do
        Cucumber::Rake::Task.new(:run) do |t|
            t.cucumber_opts = "-f pretty --format rerun --out rerun.txt"
        end

        is_first_run_successful = run_rake_task ("run")

        if not is_first_run_successful
            Cucumber::Rake::Task.new(:rerun) do |t|
                t.cucumber_opts = "@rerun.txt"
            end

            run_rake_task("rerun")
        end
    end

    def run_rake_task(name)
        begin
            Rake::Task[name].invoke
        rescue Exception => e
            puts e
            return false
        end
        true
    end
end

$ rake test:execute
