Feature: Run preview server before hook
Scenario: When run
Given a fixture app "preview-server-hook-app"
And the default aruba timeout is 30 seconds
When I run `middleman server --server-name localhost --bind-address 127.0.0.1` interactively
And I stop middleman if the output contains:
"""
### END ###
"""
Then the output should contain:
"""
/// 127.0.0.1:4567 ///
/// 4567 ///
/// localhost ///
/// http://localhost:4567 ///
"""
