Locust学习笔记(3) - 一个简单的出库demo

在做一个测试之前,首先需要分析请求的过程,请求参数的信息,返回的信息
完成分析之后,再着手脚本的编写
最后通过Locust并发请求

本文是简单的模拟商品出库的流程,分为3个步骤
1.根据商品的barCode查询商品
2.根据用户的手机号查询用户
3.商品出库

所以实现的过程如下:

1.实现查看商品的请求
2.实现查看会员的请求
3.将前面两个请求的响应里所需要的信息取回来
4.构造销售出库的请求
from locust import HttpLocust, TaskSet, task, between
from random import randint
import json

class TestLogin(TaskSet):
    # 每个虚拟用户都需要执行一次
    def on_start(self):
        self.login_data = [{"username": "user1", "password": "pwd1"}, {"username": "user2", "password": "pwd2"},
                           {"username": "user3", "password": "pwd3"}]
        self.ranIndex = randint(0, len(self.login_data) - 1)
        self.barCodes = ['1001', '1002', '1003']
        self.customers = ['22222222', '11111111']
        self.doLogin()

    # 获取给定List中的随机值
    def randomValue(self, myList):
        ranIndex = ranInt(1, 10000) % len(myList)
        return myList[ranIndex]

    # 登录
    def doLogin(self):
        print(self.login_data[self.ranIndex])
        response = self.client.post("/admin/", data=self.login_data[self.ranIndex], catch_response=Ture)
        print(response.text)
        # 断言
        if "login-pass" in response.text:
            response.success()
        else:
            response.failure("Can not login!")

    # 返回随机商品的价格
    def getGoods(self):
        # 请求地址:http://localhost:8080/WoniuSales/sell/barcode
        # 参数:barcode=1001
        body = {'barcode': self.randomValue(self.barCodes)}
        # response为一个Json对象
        response = self.client.post('/WoniuSales/sell/barcode', body)
        newText = json.loads(response.text)
        return newText[0]['unitprice']

    # 获取会员的信息
    def getCustomerInfo(self):
        # 请求地址:http://localhost:8080/WoniuSales/customer/query
        # 参数:customerphone=11111111
        body = {"customerphone": self.randomValue(self.customers)}
        response = self.client.post('/WoniuSales/customer/query', body)
        newText = json.loads(response.text)
        # python 返回多个值
        return newText[0]['customerphone'], newText[0]['credittotal']

    # 销售出库的请求
    @task
    def doSell(self):
        # 请求地址:http://localhost:8080/WoniuSales/sell/summary
        # 参数:customerphone,paymethod,totalprice,creditratio,creditsum
        #        tickettype,ticketsum,oldcredit
        price = int(self.getGoods() * 0.78)
        phone, creditTotal = self.getCustomerInfo()
        body = {
            "customerphone": phone,
            "paymethod": "现金",
            "totalprice": price,
            "creditratio": "2.0",
            "creditsum": price * 2,
            "tickettype": "",
            "ticketsum": "0",
            "oldcredit": creditTotal
        }
        response = self.client.post('/WoniuSales/sell/summary', body, catch_response=True)
        # 断言(简单断言)
        if response.text.isdigit():
            response.success()
        else:
            response.failure("can not sell!!!!!!!!!")


class WebSite(HttpLocust):
    task_set = TestLogin
    wait_time = between(3, 7)

总结:以上代码可以看出,重点还是在于分析请求的过程和处理response返回的信息。Locust只是提供一个并发的功能。

在调试过程中,可以一个请求一个请求的挨个调试
