Design

Setup

  1. Restart B2G process

Test

  1. Invoke launch programmatically
  2. Inject the Performance Helper and save start time
  3. Instrumented throws timeline events at appropriate times
  4. Performance helper observes events
  5. Event emit times are compared with start time for time elapsed

Execution

  1. Test should be executed 30 times, take average and median
