yaml结合数据驱动编写测试用例

文章中示例源码获取地址：https://github.com/wmm0165/auditcenter_190912

1.yaml格式介绍

基本格式

k: v(:后必须有空格)

减号-表示列表

- desc: 机构列表
  api: /api/v1/zoneForReport
  method: get
  data:
    - test1
    - test2
  params:
    keyword: null
  headers:
    Content-Type: application/json
  assert_code: 200

等价于：
[{'desc': '机构列表', 'api': '/api/v1/zoneForReport', 'method': 'get', 'data': ['test1', 'test2'], 'params': {'keyword': None}, 'headers': {'Content-Type': 'application/json'}, 'assert_code': 200}]

-分隔多个测试用例

- desc: 机构列表
  api: /api/v1/zoneForReport
  method: get
  data:
    - test1
    - test2
  params:
    keyword: null
  headers:
    Content-Type: application/json
  assert_code: 200
- desc: 门诊科室列表
  api: /api/v1/deptForReport
  method: get
  data: null
  params:
    type: 1
    keyword: null
  headers:
    Content-Type: application/json
  assert_code: 200

等价于：
[{'desc': '机构列表', 'api': '/api/v1/zoneForReport', 'method': 'get', 'data': ['test1', 'test2'], 'params': {'keyword': None}, 'headers': {'Content-Type': 'application/json'}, 'assert_code': 200}, {'desc': '门诊科室列表', 'api': '/api/v1/deptForReport', 'method': 'get', 'data': None, 'params': {'type': 1, 'keyword': None}, 'headers': {'Content-Type': 'application/json'}, 'assert_code': 200}]

2.读取yaml文件

import yaml
import os
from config.config import YAML_PATH


class HandleYaml:
    def __init__(self):
        pass

    def read_yaml(self, filename):
        with open(os.path.join(YAML_PATH, filename), 'r', encoding='utf8') as f:
            file_content = yaml.load(f, Loader=yaml.FullLoader)
        datas = [tuple(i.values())[1::] for i in file_content]
        print(file_content)
        return datas

3.使用pytest进行数据驱动

import pytest
from common.request import HttpRequest
from common.handle_yaml import HandleYaml

requ = HttpRequest()
hy = HandleYaml()
datas = hy.read_yaml('auditcenter.yaml')
print(datas)
auditcenter_url = 'http://10.1.1.89:9999/auditcenter'


@pytest.mark.parametrize("api,method,data,params,headers,assert_code", datas)
def test_single_api(api, method, data, params, headers, assert_code):
    res = requ.req(auditcenter_url + api, method, data, params, headers)
    assert res.json()['code'] == str(assert_code)
