Aest 功能强大的NodeJS Restful 接口测试工具

项目地址：https://github.com/wangduandu...

功能强大的REST接口测试工具, Power By Jest, axios, superstruct, mustache, lodash

非常简单: 大部分工作量在于写配置文件

请求模板: 可以在配置文件中加入运行时变量，如/users/{{id}}

响应体结构验证: 支持对响应体的字段类型进行严格校验，多字段、少字段、字段类型不符合预期都会报错

非常详细的报错提示: 参见截图

yarn add aester
npm i aester -S

// filename 必须以 test.js结尾

const Ae = require("aester")
var testData = require("./test-data.js")

// 初始化配置文件
testData = Ae.init(testData)

describe("4XX 5XX error response test", () => {
  test("Get User Info without sessionId", async () => {
    await expect(Ae.send(testData.getOneUser, {id: "1"})).rejects.toHaveProperty("status", 403)
  })

  test("loginByEmail Fail Test", async () => {
    await expect(Ae.send(testData.loginByEmail, {password: "111"})).rejects.toHaveProperty("status", 401)
  })
})

describe("2XX success response test", () => {
  test("loginByEmail Success Test", async () => {
    // 对于符合预期的正向测试，不需要使用expect, 如果响应状态码是400以上，或者响应体结构不符合预期，
    // 该测试用例会自动失败
    const data = await Ae.send(testData.loginByEmail, {password: "000"})
    Ae.share("sessionId", data.sessionId)
  })

  test("Get User Info", async () => {
    await Ae.send(testData.getOneUser, {id: "1"})
  })
})

describe("2XX success response with error body struct", () => {
  test("StructError test", async () => {
    var data = _.cloneDeep(testData.getOneUser)
    data.resBodyStruct.test = "number" // set a error struct

    await expect(Ae.send(data, {id: "1"})).rejects.toHaveProperty("type", "StructError")
  })
})

// test-data.js
module.exports = {
  $baseUrl: "http://localhost:3000",
  loginByEmail: {
    desc: "login",
    req: {
      method: "post",
      path: "/login",
      headers: { "content-type": "application/x-www-form-urlencoded" },
      data: "email=wdd@cc.tt&password={{password}}",
      params: {
        _test: 1
      }
    },
    resBodyStruct: {

    }
  },
  getOneUser: {
    desc: "get user info",
    req: {
      path: "/users/{{id}}",
      headers: {
        "sessionId": "{{sessionId}}" // 如果share中有sessionId, 在请求发送时，会自动将{{sessionId}}替换成真正的值，否则会被替换成空字符串
      }
    },
    resBodyStruct: {
      id: "string",
      email: "string",
      password: "string",
      userName: "string",
      likes: "array",
      isAdmin: "boolean"
    }
  },
  createOneUser: {

    req: {
      method: "post",
      path: "/users",
      headers: {

      }
    }
  },

    desc: "update user",
    req: {

      path: "/users/{{id}}",
      headers: {
        "sessionId": "{{sessionId}}"
      }
    }
  }
}

在package.json加入

  "scripts": {
    "test": "jest"
  }

然后运行npm test

yarn add jest-html-reporter -D

然后在package.json中加入如下字段

"test:report": "jest --reporters="jest-html-reporter""

然后运行

npm run test:report

创建jest.config.js在项目根目录

module.exports = {
  verbose: true,
  testEnvironment: "node",
  reporters: [
    "default",
    ["./node_modules/jest-html-reporter", {
      pageTitle: `operation api test ${process.env.testConfigEnv}`,
      includeFailureMsg: true // 详细错误提示
    }]
  ]
}

然后运行

npm test

 PASS  test/index.test.js

例如，resBodyStruct配置sessionId为number格式，但是返回的格式是字符串，将会如下格式的报错

    TypeError: Expected a value of type `number` for `sessionId` but received `"123456"`.

      61 |         let Scheme = struct(conf.resBodyStruct)

         |                             ^
      63 |         if (result.length === 1) {

初始化配置文件

const Ae = require("aester")

...
var conf = Ae.init(apiConfs)

发送请求。

options会与share合并，然后将对应变量渲染到请求模板中。

const Ae = require("aester")

...
Ae.send(testData.getOneUser, {id: "1"}

设置共享变量

const Ae = require("aester")

...
var conf = Ae.share("token", "123123")

获取所有共享变量

const Ae = require("aester")

...
var conf = Ae.getShare() // {token: "123123"}

desc | 否 | 接口说明
req | 是 | 请求对象
req.method | 否 | 请求方法，默认get
req.path | 是 | 请求路径
req.headers | 是 | 默认为空对象，默认设置"content-type": "application/json; charset=UTF-8"
resBodyStruct | 否 | 响应体格式校验对象

resBodyStruct字段说明

{
  key: keyType
}

字段类型支持如下

any: 任意

number: 数字

array: 数组

string: 字符串

boolean： 布尔值

null: null

undefined: undefined

object: 对象类型

在字段类型后加上?表示字段是否可选

如：

{
  sessionId: "string?" //sessionId是字符串，但是可以没有这个字段
}
