Locust 类的使用

 HttpLocust类

可定义多个HttpLocust类，即多个用户可执行不一样的任务或者相同的任务，可是执行频率不同，用weight进行约定。

# coding:utf-8
from locust import HttpLocust, TaskSet, task import urllib3 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) class UserTask1(TaskSet): @task def task1(self): self.client.get("/", headers=header, verify=False) class UserTask2(TaskSet): @task def task2(self): self.client.get("/belle-ls/", verify=False) class UserOne(HttpLocust): weight = 1 task_set = UserTask1 class UserTwo(HttpLocust): weight = 2 task_set = UserTask2

 终端命令：

1 $ locust -f locustDemo2.py UserOne UserTwo --host=https://www.cnblogs.com 2 [2019-03-07 14:55:49,299] LiuShuangdeiMac.local/INFO/locust.main: Starting web monitor at *:8089
3 [2019-03-07 14:55:49,300] LiuShuangdeiMac.local/INFO/locust.main: Starting Locust 0.9.0 4 [2019-03-07 14:55:58,657] LiuShuangdeiMac.local/INFO/locust.runners: Hatching and swarming 10 clients at the rate 10 clients/s... 5 [2019-03-07 14:55:59,678] LiuShuangdeiMac.local/INFO/locust.runners: All locusts hatched: UserTwo: 7, UserOne: 3

运行结果以下，UserTwo 的执行频率是UserOne的两倍多

 

TaskSet类：执行频率的约定及嵌套

1. task修饰符 @task or @task(1)  1为权重，权重越高，执行比例越大

2. taskSet嵌套，须要用 interrupt()跳出

 写法1：

# coding:utf-8

from locust import HttpLocust, TaskSet, task import urllib3 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) class UserTask(TaskSet): @task(2) class stayMe(TaskSet): @task(2) def MyHome(self): self.client.get("/belle-ls/", verify=False)  @task(4) def MyCote(self): self.client.get("/belle-ls/category/1412671.html", verify=False)  @task(1) def Out(self): self.interrupt() #跳出当前TaskSet类，才有机会执行其余行为
 @task(1) def BlogHome(self): self.client.get("/", verify=False) class User(HttpLocust): task_set = UserTask

写法2：

class stayMe(TaskSet): @task(2) def MyHome(self): self.client.get("/belle-ls/", verify=False) @task(4) def MyCote(self): 　　　　 self.client.get("/belle-ls/category/1412671.html", verify=False) @task(1) def Out(self): self.interrupt() class UserTask(TaskSet): tasks= {stayMe:2} @task(1) def BlogHome(self):self.client.get("/", verify=False)class User(HttpLocust): task_set = UserTask

 

ResponseContextManager类：

class UserTask(TaskSet): @task(1) def BlogHome(self): with self.client.get("/", headers = header, catch_response = True, verify = False) as response: if response.status_code == 200: response.failure('Failed!') else: response.success() class User(HttpLocust): task_set = UserTask

ResponseContextManger类是Response类的子类，多了两个failure()和success()方法。

上面的例子：使用with语句及catch_response参数能够截获原始响应，把全部status_code是200的响应都当作失败响应。这里success()和failure(str)的调用会体如今结果的统计上。

 

合并请求：

好比进入博客分类，其实属于一条测试用例，可是因为参数的不一样，会再测试结果中显示两行，好比：

https://www.cnblogs.com/belle-ls/category/1412671.html

https://www.cnblogs.com/belle-ls/category/1411809.html

如何合并呢？能够在get请求参数中加个name参数来将统计叠加在一块儿，name也能够用来对Name显示为路径进行重命名

class UserTask(TaskSet): @task(1) def BlogHome(self): self.client.get("/belle-ls/category/1412671.html", headers=header, verify=False, name = "category") self.client.get("/belle-ls/category/1411809.html", headers=header, verify=False, name = "category") class User(HttpLocust): task_set = UserTask

效果：
