Why:
These methods are used internally for the functionality of the library
and are subject to change. Therefore shouldn't be part of the public
interface.
This PR:
- Moves the ```register_factory``` and ```factory_by_name``` methods to
the ```FactoryBot::Internal``` class.
- Deprecates the use of ```register_factory``` and ```factory_by_name```
from the ```FactoryBot``` module.
- Improve formatting of the specs
Fixes [#1259]
Fixes [#1267]
In [#1156] we added support for looking up local traits with either a
symbol or string. This matches the lookup for factories and for global
traits.
We were calling `to_sym` on the trait arguments passed in when
building an object, assuming that those arguments would always respond
to `to_sym`. This leads to a confusing error message when passing an
object that doesn't respond to that method.
This PR replaces the confusing "NoMethodError: undefined method `to_sym`
for ..." with a more helpful "KeyError: Trait not registered: ...". It
ensures that all trait resolution is done using strings instead of
symbols, all objects should have a `to_s` method.
