/**
* Support for testing with the creation of a list of issues
*
*
* #### Description of motivation
*
* We have two different behaviors for the code related to
* "CodeException":
*
* ```
* $codebase->config->throw_exception = true; // or false
* ```
*
* When `throw_exception` is set to `true`, code execution stops once
* the first issue is emitted, thus it may mask any problems after
* that point.
*
* When `throw_exception` is set to `false`, the code will continue
* to be executed and we can uncover some additional bugs.
*
* This is trait allows testing for the second case, when the value of
* "throw_exception" will be "false".
*
