如何在Locust中设置失败？
如何在Locust中设置失败？
提问于 2019-09-26 05:59:02
我正在我的蝗虫设置中进行验证，如果验证失败，我希望蝗虫立即退出。
为了做到这一点，我抛出了一个异常，但是locust会继续进行测试，直到达到时间限制。
如果安装失败，我希望它甚至不启动测试。有没有办法做到这一点？
蝗虫代码
class MyLocust(Locust):
task_set = MyTaskSet
def setup(self):
if True:
raise ValueError('Setup failed')stdout / stderr：

对我来说-对这件事有帮助。只有一个问题-- locust退出时代码为0，比如"successful“
import greenlet
class MyLocust(Locust):
task_set = MyTaskSet
def setup(self):
if True:
raise greenlet.error('Setup failed')Stack Overflow用户

如果你想停止单一蝗虫，使用下面的代码。locust.exceptions将帮助停止单蝗虫操作。
from locust.exception import StopLocust
class MyLocust(Locust):
task_set = MyTaskSet
def setup(self):
if True:
raise StopLocust()如果你想停止所有蝗虫，使用下面的代码。
from locust.main import runners
class MyLocust(Locust):
task_set = MyTaskSet
def setup(self):
if True:
raise runners.locust_runner.quit()Stack Overflow用户

您可以随时使用quit()一起退出蝗虫。另一种选择是使用raise StopLocust()：
class MyLocust(Locust):
task_set = MyTaskSet
def setup(self):
if True:
raise StopLocust()另外，请查看Stopping a locust
