This test is not about the contents of the runs, but about generating useful output. You can add one or more resultWriters to catch the output of an algorithm. It also works for a model or observer if it supports the OpenDA resultWriter mechanism. In the main OpenDa input file (*.oda) you can specify what data to collect. The class used for the resultWriter determines the file format. eg. . results_dud.m . results_dud.csv . results_dud_.nc Selections can be added to limit the output for a resultWriter. eg. . results_dud_algorithm.m . results_dud_model.m . results_dud_observer.m . results_dud_other.m . results_dud_costTotal_only.m
