[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

Calabash-iOS on Physical Devices

0. Prepare the environment

1. Link calabash.framework to your XCode project

$ bundle exec calabash-ios download

After that, you have build your apps on real machine.

2. Install and generate Calabash-ios folder

$ gem install calabash-cucumber
$ calabash-ios gen

3. Start to run your test

• BUNDLE_ID : Your apps bundle_ID
• DEVICE_TARGET : Your devices UDID
• DEVICE_ENDPOINT : Your devices IP

$ export BUNDLE_ID=com.example.MyApp-cal
$ export DEVICE_TARGET=< UDID >
$ export DEVICE_ENDPOINT=http://<ip>:37265
$ bundle exec cucumber

Tips: To get UDID from command line

udid=$(ideviceinfo | grep UniqueDeviceID | awk '{ print $2}')
