Name:

    testsuite::test_set_Vm - test if setting V_m work via SetModelStatus and SetStatus

Synopsis:

    (test_set_Vm) run -> dies if assertion fails

Description:

      This test goes through all models in modeldict for which V_m can be
      set, and attempts to set V_m via SetModelStatus and SetStatus. It then
      compares results. If both ways of setting V_m give different results,
      something is wtong with state initialization.

Remarks:

      The tests exploits that almost all neuron models have a state variable
      V_m. It ignores all other models (the test returns true for them). The
      new membrane potential that is set it the potential found in the
      neuron +0.1mV. This should not conflict with any limitation requiring
      the potential to be set to subthreshold values, but in pathological
      cases it may lead to the exclusion of a model that should be tested.
