title: How do I structure node.js mocha tests
body: <p>I'm very beginner for unit testing in node.js, I want to know what is the best practice of writing unit testing in node.js for example 'it' method how many assert test cases I can have, Is there any standard of writing only one test case in single it method. Please give me an idea to write the unit test case.
  Thanks in advance.:)</p>
