Access STDERR of command

You may need to #stop_all_commands before accessing #stderr of a single
command - e.g. #last_command_started.

Background
Given
I use a fixture named "cli-app"
And
the default aruba io wait timeout is 1 seconds
Scenarios
Existing executable
Given
an executable named "bin/aruba-test-cli" with:
#!/bin/bash
echo 'Hello, Aruba!' >&2
And
a file named "spec/run_spec.rb" with:
require 'spec_helper'

RSpec.describe 'Run command', :type => :aruba do
  before(:each) { run('cli') }
  before(:each) { stop_all_commands }
  it { expect(last_command_started.stderr).to start_with  'Hello' }
end
When
I run rspec
Then
the specs should all pass
Waiting for output to "appear" after 2 seconds
Given
an executable named "bin/aruba-test-cli" with:

RSpec.describe 'Run command', :type => :aruba, :io_wait_timeout => 2 do

  it { expect(last_command_started.stderr).to start_with 'Hello' }
