使用seldom编写http接口用例

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_dataclass 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_dataclass 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_dataclass 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_dataclass 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":passif __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。
