How to do it...

Modify app_tests.py to accommodate mocking of the geoip lookup:

1. First, configure the mocking of the geoip lookup by creating patchers:

from unittest import mockimport geoip2.records 
 
class CatalogTestCase(unittest.TestCase): 
 
    def setUp(self): 
        # .. Non changed code .. 
        self.geoip_city_patcher = mock.patch('geoip2.models.City',            location=geoip2.records.Location(time_zone =             'America/Los_Angeles')        )        PatchedGeoipCity = self.geoip_city_patcher.start()        self.geoip_reader_patcher =         mock.patch('geoip2.database.Reader')        PatchedGeoipReader = self.geoip_reader_patcher.start()        PatchedGeoipReader().city.return_value = PatchedGeoipCity 
        db.create_all() 

First, we imported records from geoip2, which we will use to create the mocked return value ...
