测试用例

通过json/yaml文件等方式定义测试用例，实现代码与数据分离。一个用例文件如下：

{
  "name": "用例名称",
  "author": "用例作者",
  "createTime": "(可选)创建时间",
  "lastModifyTime": "(可选)最后修改时间",
  "lastModifiedAuthor": "(可选)最后修改人",
  "summary": "用例描述",
  "comment": "(可选)备注说明",
  "precondition": {
    "version": "系统版本",
    "function": [
      {
        "prefunc": "前置函数名称",
        "args": [
          {
            "name": "参数名",
            "type": "参数数据类型",
            "value": "参数值"
          }
        ]
      }
    ],
    "dependency": [
      "依赖接口1",
      "依赖接口2",
      "..."
    ]
  },
  "step": [
    {
      "input": {
        "http": {
          "version": "HTTP协议版本",
          "ip": "HTTP请求的IP地址",
          "port": "HTTP请求的端口",
          "path": "HTTP请求的路径",
          "url": "HTTP请求的完整URL",
          "method": "GET/POST/DELETE",
          "param": [
            {
              "name": "参数名",
              "type": "参数数据类型",
              "value": "参数值"
            }
          ]
        },
        "cm": {
          "server": "webadmin",
          "cmd": "01",
          "param": [
            {
              "name": "参数名",
              "type": "参数数据类型",
              "value": "参数值"
            }
          ]
        }
      },
      "output": {
        "strict": "严格匹配，不允许返回其他变量",
        "match": [
          {
            "var": "输出的变量名",
            "opt": "比较运算符（大于／等于／小于／不等于／加减N/正则满足/...）",
            "val": {
              "type": "期望数据类型",
              "value": "期望数据的值"
            }
          }
        ]
      }
    }
  ]
}

运行示例

import os
from src import task


def main():
    """"""
    _case_path = os.path.join(os.path.dirname(__file__), 'case', 'sample.json')
    testcase =task.OneCase(case_path=_case_path)
    testcase.run()

    # 输出结果:

    # 测试通过时:
    #   All steps passed for case: test

    # 测试不通过:
    #   Failed on case: test
    #   Step 1 failed for reason:
    #       Not equal!
    #       Expect: 201
    #       Got: 200

扩展接口协议

可通过继承IConnection类来实现私有协议接口的测试，IConnection类定义如下，只需要实现send和response方法：

from abc import ABCMeta, abstractmethod, abstractproperty


class IConnection(object):
    """Connection interface for different connection in different protocol"""
    __metaclass__ = ABCMeta

    def __init__(self, *args, **kwargs):
        self.name = None

    @abstractmethod
    def send(self, *args, **kwargs):
        raise NotImplementedError

    @abstractproperty
    def response(self, *args, **kwargs):
        raise NotImplementedError
