Distributed environment testing

I have started the all the NFs and the UPF,and manually exec the test command:
/usr/local/go/bin/go test -v -vet=off -run TestRegistration

the AMF receives the HTTP2 response of nnrf-disc from the NRF,but not to request “/nausf-auth/v1/ue-authentications” to the AUSF?

the AMF info:

When you run the NF distribute and manually, you shouldn’t run the test. The test is for all in one and will automatically bring up each NF on the same host and connect to each others.

If you want to test for distributed environment, you can try to modify the test script.

I have tested the registration procedure manually, but found that the AMF’s HTTP2 request was sent slowly.sometimes, each request takes a few minutes.

in the line 250 of /usr/local/go/src/net/http/client.go
resp,err = rt.RoundTrip(req)
