public function ParserTest::testMappingDuplicateKeyBlock in Lockr 7.3

> It is an error for two equal keys to appear in the same mapping node. > In such a case the YAML processor may continue, ignoring the second > `key: value` pair and issuing an appropriate warning. This strategy > preserves a consistent information model for one-pass and random access > applications.
