examples of unit testing methods that are expected to return JSON

Question

How does one unit test an object or collection - specifically a JSON packet?? Do you just test for he structure, key/values pairs? regardless of values??

Do I create an empty collection? and compare? same question applies to any complex object (query,structure,array, etc)

Any help by real examples would be greatly appreciated.

• Im just getting started with TDD, and using MXUnit... Im not really quite sure where to begin... Here is a sample of one basic test,

  // Arrange 
      // obj set up - handled in "setup"
  
  // Act 
      var expect = 1;         
      var result = obj.getPersonByID();
      debug( result ); // throws data back to the tester for display
  
  // Assert 
      assertEqual( expect, result, 'Expected #expect#, got #result#.' );

Use the following process:

• Create a mock JSON
• Deserialize JSON to a struct using DeserializeJSON
• Create an array of keys using StructKeyArray
• Loop through the array
• Assert the name of each key
