Features

• Run for length of time
• Run for number of iterations
• Run for both and stop at whichever comes first
• Reuse RSpec structure
• Running semantics:
  • I want to run for N iterations limited to X minutes in CI
  • I want to run for a few seconds with rake
• I want to run for a shorter period of time with guard
