+None of the following tests really depend on the content of the request, so
+we'll just pass in None.
+
+>>> request = None
+
+>>> band = Band(name='The Doors', bio='')
+
+Under the covers, the admin system will initialize ModelAdmin with a Model
+class and an AdminSite instance, so let's just go ahead and do that manually
+for testing.

+# form/fields/fieldsets interaction ##########################################
+
+fieldsets_add and fieldsets_change should return a special data structure that
+is used in the templates. They should generate the "right thing" whether we
+have specified a custom form, the fields arugment, or nothing at all.
+
+Here's the default case. There are no custom form_add/form_change methods,
+no fields argument, and no fieldsets argument.
+
+>>> ma = ModelAdmin(Band, site)
+>>> ma.fieldsets_add(request)
+[(None, {'fields': ['name', 'bio']})]
+>>> ma.fieldsets_change(request, band)
+[(None, {'fields': ['name', 'bio']})]
+
+
+If we specify the fields argument, fieldsets_add and fielsets_change should
+just stick the fields into a formsets structure and return it.
+
+>>> class BandAdmin(ModelAdmin):
+...     fields = ['name']
+
+>>> ma = BandAdmin(Band, site)
+>>> ma.fieldsets_add(request)
+[(None, {'fields': ['name']})]
+>>> ma.fieldsets_change(request, band)
+[(None, {'fields': ['name']})]
+
+
+
+
+If we specify fields or fieldsets, it should exclude fields on the Form class
+to the fields specified. This may cause errors to be raised in the db layer if
+required model fields arent in fields/fieldsets, but that's preferable to
+ghost errors where you have a field in your Form class that isn't being
+displayed because you forgot to add it to fields/fielsets
+
+>>> class BandAdmin(ModelAdmin):
+...     fields = ['name']
+
+>>> ma = BandAdmin(Band, site)
+>>> ma.form_add(request).base_fields.keys()
+['name']
+>>> ma.form_change(request, band).base_fields.keys()
+['name']
+
+>>> class BandAdmin(ModelAdmin):
+...     fieldsets = [(None, {'fields': ['name']})]
+
+>>> ma = BandAdmin(Band, site)
+>>> ma.form_add(request).base_fields.keys()
+['name']
+>>> ma.form_change(request, band).base_fields.keys()
+['name']
