Hey Chris,
First off, welcome to the LoadUI community! Now to solving your issue, from the sound of it you want to view all the traffic that goes from your webrunner to the endpoint you are hitting. Let's remember that Fiddler is a proxy that allow us to inspect the requests that leaves the local machine through a proxy.
The proxy resides at port
localhost:8888 according to
docs.telerik.com/fiddler Now, webrunner is using HttpClient under the hood, where you need to explicitly tell it to use a proxy as it wont magically pick it up like chrome seems to be doing. At least i didn't need to configure anything in order for fiddler to pick up my chrome-browsers traffic.
In LoadUI 2.6.8 the easiest way to solve this is to enter the fiddler proxy directly into the webrunners settings.
Open your webrunners settings:
Select Menu -> Settings -> Proxy
Enter the following fields: Proxy host -> localhost
Proxy port -> 8888
That should be about it!
Best regards,
Mikael
