UnitTesting肖丹数据

Question

我想测试一下Shodan的数据。数据包括时间戳、爬虫ID、服务器操作系统等字段。这些内容在每次请求时都会发生变化。哇，我应该测试它们吗？

Shodan JSON数据：

{
    "city": "Mountain View",
    "region_code": "CA",
    "os": null,
    "tags": [],
    "ip": 134744072,

                "country_code": "US",
                "latitude": 37.385999999999996
            },
            "timestamp": "2017-03-04T13:54:57.176297",
            "domains": [

            ],

            "transport": "udp",
            "ip_str": "8.8.8.8"
        }
    ],
    "asn": "AS15169",
    "ports": [
        53
    ]
}

我的测试文件：

def test_shodan_api():
    assert shodan_data == ???

Answer 1

我假设您希望将实际收到的数据与录制的数据进行比较，并发现每次调用中的某些部分(时间戳)不同，因此您的完整数据永远不会与录制的数据完全匹配。

我建议从录制的数据和接收的数据中删除时间戳，并比较其余的数据：

del received_data['last_update']
del canned_data['last_update']  # you probably want to do this prior to canning the data ;-)

assert_equal(received_data, canned_data)
