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。
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"
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 X-Frame-Options: SAMEORIGIN { "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]
运行结果
