+Error reporting should be accurate:
+
+    >>> from voluptuous import *
+    >>> schema = Schema(['one', {'two': 'three', 'four': ['five'],
+    ...                          'six': {'seven': 'eight'}}])
+    >>> schema(['one'])
+    ['one']
+    >>> schema([{'two': 'three'}])
+    [{'two': 'three'}]
+
+It should show the exact index and container type, in this case a list
+value:
+
+    >>> try:
+    ...   schema(['one', 'two'])
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc) == 'expected a dictionary @ data[1]'
+    True
+
+It should also be accurate for nested values:
+
+    >>> try:
+    ...   schema([{'two': 'nine'}])
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "not a valid value for dictionary value @ data[0]['two']"
+
+    >>> try:
+    ...   schema([{'four': ['nine']}])
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "not a valid value @ data[0]['four'][0]"
+
+    >>> try:
+    ...   schema([{'six': {'seven': 'nine'}}])
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "not a valid value for dictionary value @ data[0]['six']['seven']"
+
+Errors should be reported depth-first:
+
+    >>> validate = Schema({'one': {'two': 'three', 'four': 'five'}})
+    >>> try:
+    ...   validate({'one': {'four': 'six'}})
+    ... except Invalid as e:
+    ...   print(e)
+    ...   print(e.path)
+    not a valid value for dictionary value @ data['one']['four']
+    ['one', 'four']
+
+Voluptuous supports validation when extra fields are present in the
+data:
+
+    >>> schema = Schema({'one': 1, Extra: object})
+    >>> schema({'two': 'two', 'one': 1}) == {'two': 'two', 'one': 1}
+    True
+    >>> schema = Schema({'one': 1})
+    >>> try:
+    ...   schema({'two': 2})
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "extra keys not allowed @ data['two']"
+
+dict, list, and tuple should be available as type validators:
+
+    >>> Schema(dict)({'a': 1, 'b': 2}) == {'a': 1, 'b': 2}
+    True
+    >>> Schema(list)([1,2,3])
+    [1, 2, 3]
+    >>> Schema(tuple)((1,2,3))
+    (1, 2, 3)
+
+Validation should return instances of the right types when the types are
+subclasses of dict or list:
+
+    >>> class Dict(dict):
+    ...   pass
+    >>>
+    >>> d = Schema(dict)(Dict(a=1, b=2))
+    >>> d == {'a': 1, 'b': 2}
+    True
+    >>> type(d) is Dict
+    True
+    >>> class List(list):
+    ...   pass
+    >>>
+    >>> l = Schema(list)(List([1,2,3]))
+    >>> l
+    [1, 2, 3]
+    >>> type(l) is List
+    True
+
+Multiple errors are reported:
+
+    >>> schema = Schema({'one': 1, 'two': 2})
+    >>> try:
+    ...   schema({'one': 2, 'two': 3, 'three': 4})
+    ... except MultipleInvalid as e:
+    ...   errors = sorted(e.errors, key=lambda k: str(k))
+    ...   print([str(i) for i in errors])  # doctest: +NORMALIZE_WHITESPACE
+    ["extra keys not allowed @ data['three']",
+     "not a valid value for dictionary value @ data['one']",
+     "not a valid value for dictionary value @ data['two']"]
+    >>> schema = Schema([[1], [2], [3]])
+    >>> try:
+    ...   schema([1, 2, 3])
+    ... except MultipleInvalid as e:
+    ...   print([str(i) for i in e.errors])  # doctest: +NORMALIZE_WHITESPACE
+    ['expected a list @ data[0]',
+     'expected a list @ data[1]',
+     'expected a list @ data[2]']
+
+Required fields in dictionary which are invalid should not have required :
+
+    >>> from voluptuous import *
+    >>> schema = Schema({'one': {'two': 3}}, required=True)
+    >>> try:
+    ...   schema({'one': {'two': 2}})
+    ... except MultipleInvalid as e:
+    ...   errors = e.errors
+    >>> 'required' in ' '.join([x.msg for x in errors])
+    False
+
+Multiple errors for nested fields in dicts and objects:
+
+> \>\>\> from collections import namedtuple \>\>\> validate = Schema({
+> ... 'anobject': Object({ ... 'strfield': str, ... 'intfield': int ...
+> }) ... }) \>\>\> try: ... SomeObj = namedtuple('SomeObj', ('strfield',
+> 'intfield')) ... validate({'anobject': SomeObj(strfield=123,
+> intfield='one')}) ... except MultipleInvalid as e: ...
+> print(sorted(str(i) for i in e.errors)) \# doctest:
+> +NORMALIZE\_WHITESPACE ["expected int for object value @
+> data['anobject']['intfield']", "expected str for object value @
+> data['anobject']['strfield']"]
+
+Custom classes validate as schemas:
+
+    >>> class Thing(object):
+    ...     pass
+    >>> schema = Schema(Thing)
+    >>> t = schema(Thing())
+    >>> type(t) is Thing
+    True
+
+Classes with custom metaclasses should validate as schemas:
+
+    >>> class MyMeta(type):
+    ...     pass
+    >>> class Thing(object):
+    ...     __metaclass__ = MyMeta
+    >>> schema = Schema(Thing)
+    >>> t = schema(Thing())
+    >>> type(t) is Thing
+    True
+
+Schemas built with All() should give the same error as the original
+validator (Issue \#26):
+
+    >>> schema = Schema({
+    ...   Required('items'): All([{
+    ...     Required('foo'): str
+    ...   }])
+    ... })
+
+    >>> try:
+    ...   schema({'items': [{}]})
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "required key not provided @ data['items'][0]['foo']"
+
+Validator should return same instance of the same type for object:
+
+    >>> class Structure(object):
+    ...     def __init__(self, q=None):
+    ...         self.q = q
+    ...     def __repr__(self):
+    ...         return '{0.__name__}(q={1.q!r})'.format(type(self), self)
+    ...
+    >>> schema = Schema(Object({'q': 'one'}, cls=Structure))
+    >>> type(schema(Structure(q='one'))) is Structure
+    True
+
+Object validator should treat cls argument as optional. In this case it
+shouldn't check object type:
+
+    >>> from collections import namedtuple
+    >>> NamedTuple = namedtuple('NamedTuple', ('q',))
+    >>> schema = Schema(Object({'q': 'one'}))
+    >>> named = NamedTuple(q='one')
+    >>> schema(named) == named
+    True
+    >>> schema(named)
+    NamedTuple(q='one')
+
+If cls argument passed to object validator we should check object type:
+
+    >>> schema = Schema(Object({'q': 'one'}, cls=Structure))
+    >>> schema(NamedTuple(q='one'))  # doctest: +IGNORE_EXCEPTION_DETAIL
+    Traceback (most recent call last):
+    ...
+    MultipleInvalid: expected a <class 'Structure'>
+    >>> schema = Schema(Object({'q': 'one'}, cls=NamedTuple))
+    >>> schema(NamedTuple(q='one'))
+    NamedTuple(q='one')
+
+Ensure that objects with \_\_slots\_\_ supported properly:
+
+    >>> class SlotsStructure(Structure):
+    ...     __slots__ = ['q']
+    ...
+    >>> schema = Schema(Object({'q': 'one'}))
+    >>> schema(SlotsStructure(q='one'))
+    SlotsStructure(q='one')
+    >>> class DictStructure(object):
+    ...     __slots__ = ['q', '__dict__']
+    ...     def __init__(self, q=None, page=None):
+    ...         self.q = q
+    ...         self.page = page
+    ...     def __repr__(self):
+    ...         return '{0.__name__}(q={1.q!r}, page={1.page!r})'.format(type(self), self)
+    ...
+    >>> structure = DictStructure(q='one')
+    >>> structure.page = 1
+    >>> try:
+    ...   schema(structure)
+    ...   raise AssertionError('MultipleInvalid not raised')
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> str(exc)
+    "extra keys not allowed @ data['page']"
+
+    >>> schema = Schema(Object({'q': 'one', Extra: object}))
+    >>> schema(structure)
+    DictStructure(q='one', page=1)
+
+Ensure that objects can be used with other validators:
+
+    >>> schema = Schema({'meta': Object({'q': 'one'})})
+    >>> schema({'meta': Structure(q='one')})
+    {'meta': Structure(q='one')}
+
+Ensure that subclasses of Invalid of are raised as is.
+
+    >>> class SpecialInvalid(Invalid):
+    ...   pass
+    ...
+    >>> def custom_validator(value):
+    ...   raise SpecialInvalid('boom')
+    ...
+    >>> schema = Schema({'thing': custom_validator})
+    >>> try:
+    ...   schema({'thing': 'not an int'})
+    ... except MultipleInvalid as e:
+    ...   exc = e
+    >>> exc.errors[0].__class__.__name__
+    'SpecialInvalid'
