Locust 学习之路 （集合点）

Posted 2020-12-29 grandlulu

直接编写接口事务脚本对后台接口进行测试；有时测试需要让所有并发用户完成初始化后再进行压力测试，这就需要类似于LoadRunner中的集合点的概念，由于框架本身没有直接封装，有如下办法实现：

from gevent._semaphore import Semaphore
all_locusts_spawned = Semaphore()
all_locusts_spawned.acquire()

def on_hatch_complete(**kwargs):
    all_locusts_spawned.release()

events.hatch_complete += on_hatch_complete

class TestTask(TaskSet):
    def on_start(self):
        """ on_start is called when a Locust start before any task is scheduled """
        self.login()
        all_locusts_spawned.wait()
