/* Notes:

 1. all test function names should begin with 'test'
 2. (if exists) at the beginning of module test setUpModule() module function is called
 3. (if exists) at the beginning of each test setUp() module function is called
 4. tests should use TKUnit.assert(condition, message) to mark error. If no assert fails test is successful
 5. (if exists) at the end of each test tearDown() module function is called
 6. (if exists) at the end of module test tearDownModule() module function is called
