Feature: 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"
Scenario: Existing executable
Given an executable named "bin/aruba-test-cli" with:
"""bash
#!/bin/bash
echo 'Hello, Aruba!' >&2
"""
And a file named "spec/run_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'Run command', type: :aruba do
before { run_command('aruba-test-cli') }
before { stop_all_commands }
it { expect(last_command_started.stderr).to start_with 'Hello' }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: Waiting for output to appear
Given an executable named "bin/aruba-test-cli" with:
"""bash
#!/bin/bash
sleep 0.1
echo 'Hello, Aruba' >&2
"""
And a file named "spec/run_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'Run command', type: :aruba, io_wait_timeout: 0.4 do
before { run_command('aruba-test-cli') }
it { expect(last_command_started.stderr).to start_with 'Hello' }
end
