I wish this helpful for you I'm completely "fresh" to Ruby and coming from a .NET background. , You could use it like
code :
File.open('etc/metrics_json.log').each_line do |line|
  begin
    metric_hash = JSON.parse(line)
    Metric.create(metric_hash)
  rescue RuntimeError => e
    puts e.message
  end
end

Can I assert inside a begin rescue end block?

Any of those help You can use assert_raise to test that particular exceptions are being thrown.
Exception is only caught with `rescue` at the end of the line but not when using a `begin rescue` block

may help you . I have a statement that fails:
code :
begin
   result = service.load_data()
rescue AnExceptionKlass => details    # here the name is SocketError    
   logger.fatal "Failed to load the data: #{details}"
end
require 'net/http'
Net::HTTP.start('http://www.google.com') do |http|
response = http.get('/')
puts response
end
#=> getaddrinfo: No such host is known.  (SocketError)
require 'net/http'

begin

  htt = Net::HTTP.start('http://www.google.com')
  response = htt.get('/')
  puts response

rescue SocketError => details    # or the Exception class name may be SocketError    
   p "Failed to load the data: #{details}"
end

#=> "Failed to load the data: getaddrinfo: No such host is known. "

I hope this helps . retry will execute the entire begin block, so in your case all the email loops will run again.
Here's a quick example, which will print integers 1 through 7 continuously (terminate with CTRL-C, as it will infinite loop):
code :
begin
  (1..10).each do |x|
    puts x
    if x > 6
      STDIN.gets # press enter to do another iteration
      raise ArgumentException
    end
  end
rescue
  retry # loop will restart from 1
end

hope this fix your issue Retry is called on the object on which your run_ssh_command was called.
So
code :
describe "rescues Net::SSH::HostKeyMismatch" do
  it "resyncs the ssh keys" do
    ssh_instance = ssh_class.new

    Net::SSH::HostKeyMismatch.any_instance.should_receive(:remember_host!).and_return(true)
    ssh_instance.should_receive(:retry)

    ssh_instance.run_ssh_command { raise  Net::SSH::HostKeyMismatch}
  end
end

Any of those help You could use two rescue clauses, one to catch PuppetError::Error and raise it again, then on the other catch everything else:
code :
module PuppetCert
  def self.remove(instance_hostname)
    begin
      Open3::popen3("puppet cert clean #{instance_hostname}") do |stdin, stdout, stderr, wait_thr|
        if wait_thr.value.success?
          puts "success"
        else
          raise PuppetError::Error
          return
        end
      end
    rescue PuppetError::Error => error
      raise error
    rescue
      raise PuppetError::ExecError
    end
  end
end
