在编写接口用例的过程中,针对一个接口,往往只是参数不同,那么参数化就非常有必要了。

seldom 中参数化的用法非常灵活,这里仅介绍@file_data() 的N种玩法。

二维列表

当参数比较简单时可以试试下面的方式。

  • 参数化数据
{
 "add_guest":  [
   ["参数错误", "", "", 10021, "parameter error"],
   ["查询为空", "tom", "13711001100", 10022, "event id null"],
 ]
}
  • 测试用例
import seldom
from seldom import file_data


class AddGuestTest(seldom.TestCase):

    @file_data("add_guest.json", key="add_guest")
    def test_case(self, _, real_name, phone, status, msg):
        payload = {"realname": real_name, "phone": phone}
        self.post("/api/add_guest/", data=payload)
        self.assertStatusCode(200)
        self.assertPath("status", status)
        self.assertPath("message", msg)


if __name__ == "__main__":
    seldom.main(base_url="http://127.0.0.1:8000", debug=True)

列表嵌套字典

当参数很多时,不便于阅读,可以通过字典的方式定义。

  • 参数化数据
{
  "add_guest": [
    {
      "name": "参数错误",
      "real_name": "",
      "phone": "",
      "status": 10021,
      "msg": "parameter error"
    },
    {
      "name": "查询为空",
      "real_name": "tom",
      "phone": "13711001100",
      "status": 10022,
      "msg": "event id null"
    },
  ]
}
  • 测试用例
import seldom
from seldom import file_data


class AddGuestTest(seldom.TestCase):

    @file_data("add_guest.json", key="add_guest")
    def test_case(self, _, real_name, phone, status, msg):
        payload = {"realname": real_name, "phone": phone}
        self.post("/api/add_guest/", data=payload)
        self.assertStatusCode(200)
        self.assertPath("status", status)
        self.assertPath("message", msg)


if __name__ == "__main__":
    seldom.main(base_url="http://127.0.0.1:8000", debug=True)

复杂的数据结构

我们可以将接口的入参、出参进一步拆分。

  • 参数化数据
{
  "add_guest": [
    {
      "name": "参数错误",
      "req": {
        "real_name": "",
        "phone": ""
      },
      "resp": {
         "status": 10021,
          "msg": "parameter error"
      }
    },
    {
      "name": "查询为空",
      "req": {
        "real_name": "tom",
        "phone": "13711001100"
      },
      "resp": {
        "status": 10022,
        "msg": "event id null"
      }
    }
  ]
}
  • 测试用例
import seldom
from seldom import file_data


class AddGuestTest(seldom.TestCase):

    @file_data("add_guest.json", key="add_guest")
    def test_case(self, _, req, resp):
        payload = {"realname": req["real_name"], "phone": req["phone"]}
        self.post("/api/add_guest/", data=payload)
        self.assertStatusCode(200)
        self.assertPath("status", resp["status"])
        self.assertPath("message", resp["msg"])


if __name__ == "__main__":
    seldom.main(base_url="http://127.0.0.1:8000", debug=True)

通过json编写用例

虽然不推荐用文件写用例,你想写也是可以的。

  • 测试用例文件
{
  "cases": [
    {
      "name": "参数错误",
      "method": "post",
      "url": "/api/add_guest/",
      "req": {
        "eid": "",
        "real_name": "",
        "phone": ""
      },
      "resp": {
         "status": 10021,
          "msg": "parameter error"
      }
    },
    {
      "name": "查询为空",
      "method": "post",
      "url": "/api/add_guest/",
      "req": {
        "eid": 901,
        "real_name": "tom",
        "phone": "13711001100"
      },
      "resp": {
        "status": 10022,
        "msg": "event id null"
      }
    }
  ]
}
  • 解析测试用例

import seldom
from seldom import file_data


class SampleCaseTest(seldom.TestCase):

    @file_data("test_case.json", key="cases")
    def test_case(self, _, method, url, req, resp):
        if method == "post":
            payload = {"eid": req["eid"], "realname": req["real_name"], "phone": req["phone"]}
            self.post(url, data=payload)
            self.assertStatusCode(200)
            self.assertPath("status", resp["status"])
            self.assertPath("message", resp["msg"])
        elif method == "get":
            pass


if __name__ == "__main__":
    seldom.main(base_url="http://127.0.0.1:8000", debug=True)

最后的这种写法不是seldom推荐的,假如要测试的接口足够简单,设计一个测试方法来处理简单的接口也未尝不可。当然,往往实际项目中的用例并不足够简单。回到代码的方式编写才能足够个兼具灵活性和易用性。
