+|metric        | 1. tosca file which is converted from yang file by Parser    |
+|              | 2. result whether the output is same with expected outcome   |
++--------------+--------------------------------------------------------------+
+|test purpose  | To verify the function of Yang-to-Tosca in Parser.           |

+|              | yangfile: the path of the yangfile which you want to convert |
+|              | toscafile: the path of the toscafile which is your expected  |

+|              | (Parser is not part of a Linux distribution, hence it        |
+|              | needs to be installed. As an example see the                 |
+|              | /yardstick/benchmark/scenarios/parser/parser_setup.sh for    |
+|              | how to install it manual. Of course, it will be installed    |
+|              | and uninstalled automatically when you run this test case    |
+|              | by yardstick)                                                |

+|applicability | Test can be configured with different path of yangfile and   |
+|              | toscafile to fit your real environment to verify Parser      |

+|step 1        | parser is installed without VM, running Yang-to-Tosca module |
+|              | to convert yang file to tosca file, validating output against|
+|              | expected outcome.                                            |
+|              |                                                              |
+|              | Result: Logs are stored.                                     |
++--------------+--------------------------------------------------------------+
+|test verdict  | Fails only if output is different with expected outcome      |
+|              | or if there is a test case execution problem.                |
