Question

My code is like below:

def getAllVehicles(self):
    try:
        vehobj = Vehicles.objects.all()            
    except VehicleDoesNotExists, e:
        logger.debug("Exception in getAllVehicles() is :::: %s ", e)
    return vehobj

And here is my test case:

def test_getAllVehicles(self):
    Vehicles.objects.all().delete()
    instance = Vehicles()
    self.assertRaises(VehicleDoesNotExists, instance.getAllVehicles)

Exception is never raised, but I require that:

 Vehicles.objects.all() 

to raise an exception.
Code coverage is asking me to execute the except block.

Answer 1

Vehicles.objects.all() will give you an empty list… which is the correct behavior. If you want to raise an exception, you can test for an empty list and raise VehicleDoesNotExists(...) yourself… but I don’t understand why you’d want to.
