# Generates a Shindo test that compares a hash schema to the result
|
|
# of the passed in block returning true if they match.
|
|
#
|
|
# The schema that is passed in is a Hash or Array of hashes that
|
|
# have Classes in place of values. When checking the schema the
|
|
# value should match the Class.
|
|
#
|
|
# Strict mode will fail if the data has additional keys. Setting
|
|
# +strict+ to +false+ will allow additional keys to appear.
|
|
#
|
|
# @param [Hash] schema A Hash schema
|
|
# @param [Hash] options Options to change validation rules
|
|
# @option options [Boolean] :allow_extra_keys
|
|
# If +true+ does not fail when keys are in the data that are
|
|
# not specified in the schema. This allows new values to
|
|
# appear in API output without breaking the check.
|
|
# @option options [Boolean] :allow_optional_rules
|
|
# If +true+ does not fail if extra keys are in the schema
|
|
# that do not match the data. Not recommended!
|
|
# @yield Data to check with schema
|
|
#
|
|
# @example Using in a test
|
|
# Shindo.tests("comparing welcome data against schema") do
|
|
# data = {:welcome => "Hello" }

|
# data_matches_schema(:welcome => String) { data }
