以编程方式分配蝗虫任务集
以编程方式分配蝗虫任务集
提问于 2021-09-28 01:44:18
我试图根据通过UI传递的主机值动态分配蝗虫任务。在本例中，如果主机作为" hello“传入，则测试应该运行hello任务，否则它将运行world任务。
from locust import HttpUser, TaskSet, task, events
class RandomTask1(TaskSet):
@task(1)
def soemthing(self):
print("Hello!")
class RandomTask2(TaskSet):
@task(1)
def soemthing(self):
print("World!")
class LoadTestUser(HttpUser):
def on_start(self):
host_config = self.host
if host_config == "hello":
tasks = {RandomTask1:1}
else:
tasks = {RandomTask2:1}下面的示例不起作用，我得到以下错误
Exception: No tasks defined on LoadTestUser. use the @task decorator or set the tasks property of the User (or mark it as abstract = True if you only intend to subclass it)你知道我怎么能做到这样的事吗？我已经对示例进行了简化，但对于所有意图和目的，让我们假设locust实例已经在运行，不能停止或重新启动，并且需要动态分配任务。
编辑：
试过这样做：
class LoadTestUser(HttpUser):
def on_start(self):
if self.host == "hello":
self.tasks = {HelloTask: 1}
else:
self.tasks = {WorldTask: 1}
@task
def nothing(self):
pass
class HelloTask(TaskSet):
@task
def something(self):
print("Hello")
class WorldTask(TaskSet):
@task
def something(self):
print("World")现在我看到了以下错误：
Traceback (most recent call last):
