前言

在一个完整的测试用例中，断言是必不可少的，断言是拿实际结果和期望结果去比较，在httprunner中用validate来对比测试结果。

validate校验器

在httprunner的源码里，utils.py可以找到有哪些校验方法

def get_uniform_comparator(comparator):      """ convert comparator alias to uniform name      """      if comparator in ["eq", "equals", "==", "is"]:          return "equals"      elif comparator in ["lt", "less_than"]:          return "less_than"      elif comparator in ["le", "less_than_or_equals"]:          return "less_than_or_equals"      elif comparator in ["gt", "greater_than"]:          return "greater_than"      elif comparator in ["ge", "greater_than_or_equals"]:          return "greater_than_or_equals"      elif comparator in ["ne", "not_equals"]:          return "not_equals"      elif comparator in ["str_eq", "string_equals"]:          return "string_equals"      elif comparator in ["len_eq", "length_equals", "count_eq"]:          return "length_equals"      elif comparator in ["len_gt", "count_gt", "length_greater_than", "count_greater_than"]:          return "length_greater_than"      elif comparator in ["len_ge", "count_ge", "length_greater_than_or_equals",           "count_greater_than_or_equals"]:          return "length_greater_than_or_equals"      elif comparator in ["len_lt", "count_lt", "length_less_than", "count_less_than"]:          return "length_less_than"      elif comparator in ["len_le", "count_le", "length_less_than_or_equals",           "count_less_than_or_equals"]:          return "length_less_than_or_equals"      else:          return comparator

平常用eq比较多，eq就是equals的缩写，这里总结下相关的校验方法

  • eq equals，判断实际结果和期望结果是否相等，可以用”eq”, “equals”, “==”, “is”
  • lt less_than， 判断实际结果小于期望结果 ，可以用 “lt”, “less_than”
  • le less_than_or_equals，判断实际结果小于等于期望结果 ，可以用 “le”, “less_than_or_equals”
  • gt greater_than，判断实际结果大于期望结果，可以用”gt”, “greater_than”
  • ge greater_than_or_equals，判断实际结果大于等于期望结果，可以用”ge”, “greater_than_or_equals”
  • ne not_equals, 判断实际结果和期望结果不相等，可以用”ne”, “not_equals”
  • str_eq string_equals 判断转字符串后对比 实际结果和期望结果是否相等，可以用”str_eq”, “string_equals”
  • len_eq length_equals 判断字符串或list长度,可以用”len_eq”, “length_equals”, “count_eq”
  • len_gt length_greater_than 判断实际结果的长度大于和期望结果，可以用”len_gt”, “count_gt”, “length_greater_than”, “count_greater_than”
  • len_ge length_greater_than_or_equals 实际结果的长度大于等于期望结果，可以用”len_ge”, “count_ge”, “length_greater_than_or_equals”, “count_greater_than_or_equals”
  • len_lt length_less_than 实际结果的长度小于期望结果，可以用”len_lt”, “count_lt”, “length_less_than”, “count_less_than”
  • len_le length_less_than_or_equals 实际结果的长度小于等于期望结果，可以用”len_le”, “count_le”, “length_less_than_or_equals”, “count_less_than_or_equals”

案例

接着上一篇的demo案例，返回内容如下

C:Usersdell>http http://127.0.0.1:8000/api/test/demo  HTTP/1.1 200 OK  Content-Length: 255  Content-Type: application/json  Date: Sun, 22 Sep 2019 10:11:07 GMT  Server: WSGIServer/0.2 CPython/3.6.0  X-Frame-Options: SAMEORIGIN    {      "code": 0,      "datas": [          {              "age": 20,              "create_time": "2019-09-15",              "id": 1,              "mail": "[email protected]",              "name": "yoyo",              "sex": "M"          },          {              "age": 21,              "create_time": "2019-09-16",              "id": 2,              "mail": "[email protected]",              "name": "yoyo111",              "sex": "M"          }      ],      "msg": "success!"  }

针对上面的返回结果写几种不同的validate，校验返回结果，报错问test_validate_demo.yml

- config:      name: test_demo      variables: {}  - test:      name: test_demo case1      request:          url: http://127.0.0.1:8000/api/test/demo          method: GET          headers:              Content-Type: application/json              User-Agent: python-requests/2.18.4          json:              username: test              password: 123456      extract:          - mail: content.datas.0.mail         # 提取mail      validate:          - eq: [status_code, 200]          - less_than: [status_code, 400]          - equals: [content.code, 0]          - equals: [content.msg, success!]          - length_equals: [content.datas, 2]          - greater_than_or_equals: [content.datas.0.age, 18]

运行用例

运行结果

validate两种格式

validate支持两种格式：

  • {“comparator_name”: [check_item, expect_value]}
  • {“check”: check_item, “comparator”: comparator_name, “expect”: expect_value}

那么上面的validate校验也可以用下面这种格式

    validate:          - check: status_code            comparator: eq            expect: 200            - check: status_code            comparator: less_than            expect: 400            - check: content.code            comparator: equals            expect: 0            - check: content.msg            comparator: equals            expect: success!
