# This module assumes you have `let(:query_string)` in your spec.
# It provides `errors` which are the validation errors for that string,
# as validated against `Dummy::Schema`.
# You can override `schema` to provide another schema
# @example testing static validation
# include StaticValidationHelpers
# let(:query_string) { " ... " }
# it "validates" do
# assert_equal(errors, [ ... ])
# assert_equal(error_messages, [ ... ])
# end
module StaticValidationHelpers
def errors
@errors ||= begin
target_schema = schema
validator = GraphQL::StaticValidation::Validator.new(schema: target_schema)
query = GraphQL::Query.new(target_schema, query_string)
validator.validate(query)[:errors].map(&:to_h)
end
end
def error_messages
errors.map { |e| e["message"] }
end
def schema
# without #graphql_definition call here #errors / #error_messages will reference a different schema object
# than the one returned by schema so it's difficult to make changes in specs.
