#find_cz_pids ⇒ Object

‘START` will also create a parent process for `cmd.exe` when `ruby.exe` is created, so we also need to make sure that we find those and kill them after the ruby process is terminated. Otherwise many orphaned `cmd.exe` windows could be left open in the aftermath.

    SELECT
      ProcessID,
      ParentProcessID

      CommandLine LIKE "%chef-zero%"

#nuke_all_cz_pids ⇒ Object

It is possible to have multiple chef-zero processes running which may mess up taste-tester’s state. So… nuke ‘em all.

def nuke_all_cz_pids
  find_cz_pids.each do |pid, parentpid|
    ::Mixlib::ShellOut.new("taskkill /F /PID #{pid}").run_command
    ::Mixlib::ShellOut.new("taskkill /F /PID #{parentpid}").run_command
  end
end

#start_win_chef_zero_server ⇒ Object

We use START to spawn a subprocess of chef-zero since if you were to do this directly within a terminal session it will collide with the running chef-zero process when the user tries to input commands leading to many keystrokes being lost :(
