httprunner学习 -validate校验器
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:\Users\dell>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

{
"code": 0,
"datas": [
{
"age": 20,
"create_time": "2019-09-15",
"id": 1,
"mail": "283340479@qq.com",
"name": "yoyo",
"sex": "M"
},
{
"age": 21,
"create_time": "2019-09-16",
"id": 2,
"mail": "123445@qq.com",
"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!
