Get code coverage on Xcode5. Hacky but pragmatic.

gcovr_runner.rb

#! /usr/bin/env ruby
workspace_name = %x[ls].split.find{ |file_name| file_name.include? 'xcworkspace' }
project_name = workspace_name.split('.')[0]
pwd = %x[pwd].strip
settings = %x[xcodebuild -workspace #{workspace_name} -showBuildSettings -scheme #{project_name}]
%x[xcodebuild -workspace #{workspace_name} test -scheme #{project_name} -destination OS=6.1,name=iPad -configuration Debug]
if $? == 0
  full_build_root = settings[/BUILD_ROOT = (.*)/].split[2]
  full_build_root[/(.*)\/Build\/Products/]
  root_for_gcovr = $1
  %x[cp -R #{project_name} #{root_for_gcovr}]
  %x[cd \"#{root_for_gcovr}\"; gcovr -r #{pwd} --exclude '.*Tests.*' --exclude '.*libs.*' --exclude '.*main.m' --exclude '.*ExternalFrameworks.*' --exclude '.*Spec.*' --html --html-details -o coverage.html]
  %x[open \"#{root_for_gcovr}/coverage.html\"]
end

testloop.sh

#! /bin/bash

# poor replacement for autotest but works
kicker -c -e ./coverage.rb .
