Solve the following python programming problem given the following code:
def test_set_memcache_policy(testbed) : 
    def policy(key) : 
        return (1 == 2) 
snippets.set_memcache_policy (testbed) 
    assert (policy == ndb.get_context ().get_memcache_policy ()) 

    
    

    Fix the buggy line: snippets.set_memcache_policy (testbed)
