Does agent keep track of intercepted requests?

[jethrolam]

In my unit tests, I want to not only intercept the incoming fetch response but also verify the body of any outgoing (intercepted) fetch request. I searched through the doc but cannot find anything. Does such a feature exist?

There is an experimental API called interceptor. Its very clunky.
An example of which can be seen in the 3XX redirect handler.
