Solve the following python programming problem given the following code:
def setUp(self) : 
    super (FixedIpTest, self).setUp () 
    self.api.microversion = self.microversion 
    instance = dict (test_utils.get_test_instance (), hostname = 'compute.host.pvt', host = 'host') 
    fake_fixed_ips = [{ 
        'id' : 1, 
        'address' : '192.168.1.1', 
        'network_id' : 1, 
        'virtual_interface_id' : 1, 
        'instance_uuid' : '1', 
        'allocated' : False,

self.stub_out ('nova.db.fixed_ip_get_by_address', fake_fixed_ip_get_by_address) 
    self.stub_out ('nova.db.fixed_ip_update', fake_fixed_ip_update)
