This PR addresses #11 by making possible to catch all validation errors of a given input instead of just the first one encountered. Any feedback from
valideer
users that would find this enhancement useful would be most welcome before merging it.Summary:
Validator.full_validate()
method is introduced, similar tovalidate()
. The difference is that invalid inputs raise aMultipleValidationError
exception, a newValidationError
subclass with anerrors
attribute that captures all individual errors in a (flat) list.ContainerValidator
abstract helper class is introduced to act as a base class of container-like validators that need to report multiple errors, without duplicating the logic betweenvalidate
andfull_validate
or making the former less efficient than necessary by delegating to the latter.HomogeneousSequence
,HeterogeneousSequence
,Mapping
andObject
now extendContainerValidator
and support reporting mutiple errors out of the box.compat.py
module for Python 2/3 compatibility is replaced by six.errors.py
module.
