Re: [Grinder-development] Initialization of object once per thread

[Darren B. <bal...@gm...>]

This is exactly what I am getting along with the script, any insight as to
why the object is not available inside of the __call__ method would be
great.

The script:

from net.grinder.script import Test
from net.grinder.script.Grinder import grinder
from com.myapp.api.controllers.perf.app import CreateAppPerf

createAppTest = Test(1, "Create APP 1 Table 100 Fields")
createAppPerf = CreateAppPerf()
createAppPerf.initialize()
createAppTest.record(createAppPerf.createApp)


class TestRunner:
    def __call__(self):
        createAppPerf.createApp(1,100)
