Instrument Flipper with ActiveSupport

[jibees]

What? Why?

Add Flipper instrumentation

What should we test?

• Test a feature: for exemple unit_price
• When you create a feature (foo), you should see:

 Flipper feature(foo) adapter(active_record) add  (14.8ms)  [ result=true ]
 Flipper feature(foo) add true (15.2ms)  [ thing=nil ]

• When you delete a feature (foo), you should see a log like

Flipper feature(foo) adapter(active_record) remove  (29.5ms)  [ result=true ]
