Capturing locust traffic in Fiddler with Locust version 0.11 works just fine. Using a python virtual (3.7) and PyCharm.
I created a second python virtual (also 3.7) for the latest version of Locust v1.1.1. Execution of this version of Locust captured no traffic in Fiddler.
In Fiddler I reset The certificate :
Tools -> Options - HTTPS - Actions
Within PyCharm I've tried both Auto-detect proxy and Manual config under:
Settings -> Appearance and Behavior -> System Settings -> HTTP Proxy
Flipping the virtual env back to the locust 0.11 traces traffic in Fiddler just fine. I don't know what v1.1.1 may be doing differently. Fiddler logs do not show any sign an attempt to connect.
Curious if anyone has encountered similar behavior.
I dont think this is a certificate issue at all (if it was, the request would not go thru)
Locust configures requests to ignore proxy settings, see https://docs.locust.io/en/stable/writing-a-locustfile.html#http-proxy-settings
You can probably re-enable it, but you’ll need to check either locust source or requests documentation.
