A simple runner for Python coroutines.
import asyncio
import corunner
co_group = corunner.Group()
@co_group
async def f_1():
await asyncio.sleep(0.1)
@co_group
async def f_2():
await asyncio.sleep(0.2)
@co_group
async def f_3():
await asyncio.sleep(0.5)
@co_group
async def f_4():
raise ValueError('Whoops...')
report = corunner.run(co_group, duration=2, users=5) # runs for 2 seconds with 5 virtual users (default)
corunner.echo(report)Running the above produces something like this:
$ python main.py
