Does the MettleCI Unit Test job parameter need to be removed from a job before promoting it to a Production environment?

The unit testing is actually enabled by an environment variable, which we suggest is added as a parameter to each job for which you wish to enable unit testing. This parameter is used exclusively by MettleCI, and can be safely propagated to Production environments where it is guaranteed to be ignored. This is because the MettleCI Unit Test framework is only installed on your DataStage Development environment.
