How to get object reference from inspection-string
Suppose there is a test failing and only an inspection string is shown in the error message.
#<Class:0x007ff706e7eb68>
It would be very convenient to retrieve a reference to the object for further inspection. The following snippet will give you the object if it isn't garbage-collected yet.
ObjectSpace._id2ref '0x007ff706e7eb68'.to_i(16) >> 1
If you are asking about the strange bit shift >> 1 as I am, I'll humbly point you to
