05/05/2023, 5:26 AMHey @Sreedhar Singaraju, in that case you’ll need to configure your app to send the requests to port 9000, where WireMock is running.
WireMock can then either send responses you defined or forward the requests to the actual endpoint, but you’ll need to tell your app to go to WireMock first.

05/05/2023, 5:32 AMOk let me tell my scenario
Sreedhar Singaraju
05/05/2023, 5:33 AMThere are bunch of services which are caling into each other using resttemplate
Sreedhar Singaraju
05/05/2023, 5:33 AMi domt have liberty to go ad chanfe code to mke them call different endpoint
Sreedhar Singaraju
05/05/2023, 5:34 AMthats why i am exploring interceptors who can give me control to inject different responses and simulate failures from a service
Sreedhar Singaraju
05/05/2023, 5:34 AMexample Payment services calls Balnking Service
Sreedhar Singaraju
05/05/2023, 5:35 AMI canot change ether of servuce code
Sreedhar Singaraju
05/05/2023, 5:35 AMSo i want to mock say endpoints of Babking srvice which Paymet Service calls but inject response as per my test scenario say Internal error injection
Sreedhar Singaraju
05/05/2023, 5:37 AMi hope I could explain my scenario cearly

Bas Dijkstra
05/05/2023, 6:57 AMYes, that's clear. And the app you're testing calls the Payment service?
s
Sreedhar Singaraju
05/05/2023, 7:10 AMYes
Sreedhar Singaraju
05/05/2023, 7:10 AMApp can be treated outside platform
Sreedhar Singaraju
05/05/2023, 7:11 AMSo my intention and scope is to check out inside platform communictions and inject exceptions based on scenarios
Sreedhar Singaraju
05/05/2023, 7:11 AMso app which calls is not of scope
b
Bas Dijkstra
05/05/2023, 8:57 AMWouldn't it be much simpler to just mock the calls to the Payment service and forget about everything downstream?
If not I'm not sure how WireMock would be able to support what you're trying to do

05/05/2023, 10:17 AMeven if it to call to Payment Service the problem statement is same
Sreedhar Singaraju
05/05/2023, 10:17 AMWhat I want is without stopping the Payment Service I want to intercept the endpoint calls and provide mocked response
Sreedhar Singaraju
05/05/2023, 10:18 AMHow can it be done
Sreedhar Singaraju
05/05/2023, 10:18 AMI dont have control on who calls into Payment service as outside platform is blackbox
Sreedhar Singaraju
05/05/2023, 10:18 AMI am exploring if wiremock can intercept those calls and provide the configured responses for the defined end points
Sreedhar Singaraju
05/05/2023, 10:20 AMi know little bit about proxy-all option for the jar may help here but not quite sure

05/05/2023, 11:00 AMWhat you probably need to look into is the proxying mode indeed.
https://wiremock.org/docs/proxying/
The question is, where to put the proxy?
At some point you need to tell some of your apps to route traffic through WireMock in some way, there's no escaping that as far as I can see.
It's a little difficult without more details (and seeing what you're working with) to give a definite answer.
