From my understanding of the code in buildingspy/development/regressiontest.py, the reference results for the regression testing are always read from the following directory:

        # Check if the directory
        # "self._libHome\\Resources\\ReferenceResults\\Dymola" exists, if not
        # create it.
        refDir = os.path.join(self._libHome, 'Resources', 'ReferenceResults', 'Dymola')
        if not os.path.exists(refDir):
            os.makedirs(refDir)

We have a use case where we would like to use BuildingsPy to run tests on an auto-generated Modelica package. For this application, it would be useful if we could specify a base directory for the reference results which is outside of the generated library. This may e.g. be done by adding a new class attribute self.refDir and moving the code snippet mentioned above into the class initialization to execute it when the default refDir=None is passed to the ìnit` method.

As I understand that this proposed change may be a bit too special for all users I first wanted to ask whether there is an interest in me implementing this. As an alternative, we could also copy reference results into the library during the auto-generation process, so we could also work around this issue.
