STDERR of commands which were executed

In order to specify expected output
As a developer using Cucumber
I want to use the "the stderr should contain" step

Background
Given
I use a fixture named "cli-app"
Scenarios
  1. Detect stderr from all processes
  2. Detect stderr from all processes (deprecated)
  3. Detect stderr from named source
Detect stderr from all processes
Given
a file named "features/output.feature" with: 
Feature: Run command
  Scenario: Run command
    When I run bash -c 'printf "hello world!\n" >&2'
    And I run bash -c 'cat >&2 ' interactively
    And I type "hola"
    And I type ""
    Then the stderr should contain:
    """
    hello world!
    """
    And the stderr should contain:
    """
    hola
    """
    And the stdout should not contain anything
When
I run cucumber
Then
the features should all pass

Detect stderr from named source
Given
a file named "features/output.feature" with: 
Feature: Run command
  Scenario: Run command
    When I run bash -c 'printf hello >&2'
    And I run printf goodbye
    Then the stderr from "bash -c 'printf hello >&2'" should contain "hello"
    And the stderr from "bash -c 'printf hello >&2'" should contain exactly "hello"
    And the stderr from "bash -c 'printf hello >&2'" should contain exactly:
    """
    hello
    """
    And the stdout from "bash -c 'printf hello >&2'" should not contain "hello"
    And the stderr from "printf goodbye" should not contain "hello"
When
I run cucumber
Then
the features should all pass
