创建好Locust脚本(locust file),模拟好场景
locust -f locust_file.py
import gevent
from locust import HttpUser,task,between
from locust.env import Environment
from locust.stats import stats_printer
from locust.log import setup_logging
setup_logging("INFO",None)
class WebUser(HttpUser):
    wait_time = between(1,5)
    host = ‘https://blog.51cto.com‘
    @task
    def open_blog1(self):
        with self.client.get(‘/13734261/2538770‘,catch_response=True) as res:
            if res.status_code == 200:
                res.success()
    @task
    def open_blog2(self):
        with self.client.get(‘/13734261/2538745‘,catch_response=True) as res:
            if res.status_code == 200:
                res.success()
#创建环境和runner
env = Environment(user_classes=[WebUser,])
env.create_local_runner()
#start a WebUI instance
env.create_web_ui("127.0.0.1",8001)
#开启了协程,会定期打印runner状态
gevent.spawn(stats_printer(env.stats))
#开启测试,开启用户数为1
env.runner.start(1,hatch_rate=10)
# 设置100秒后,然后停止测试
gevent.spawn_later(100,lambda: env.runner.quit())
#等待greenlet结束
env.runner.greenlet.join()
#结束locust webUI
env.web_ui.stop()测试输出结果如下,测试过程中,也会定期输出这样的测试结果表格,一般是隔几秒输出一次吧。
