/**
 * ServiceNow JavaScript Bugs

 * Executes a suite of tests to verify proper JavaScript implementation.
 * Test failures will output "FAIL: expected <actual> to be <expected>" after test description.
 * Or produce compiler exception, e.g.: 'Allows keywords as property names' test.
 * Outputs using console.log() if console object is found (i.e., browser or node.js),
 * otherwise uses gs.info().
