I think this is documented poorly but basically when you did server = StopableWSGIServer.create(...) the server is already running at that point. The run() method is not necessary when using create(). It is only necessary if you don't use the create() helper and directly instantiate a StopableWsgiServer yourself.
You can see this in the code here https://github.com/Pylons/webtest/blob/0b9d1a748e6c1436cdb1e6fd6c251d201a487aac/webtest/http.py#L117-L120 On Thu, Oct 1, 2015 at 9:38 AM, Alain Désilets <[email protected]> wrote: > I am working on some integration tests for a Pyramid app, and I want to > run the under StopableWSGIServer, in the same process as the tests.
