# Use child router in the test cases

I have two routers in my app. I am forwarding api calls which start with `/admin_api/v1` to a child router from the main router.

``````                       forward "/admin_api/v1", Admin.ApiWeb.Router
``````

It works fine when I test it with Postman. Both routers are working as expected. This is path in the child router.

``````            qa_question_path  DELETE  /qa_questions/:nuton_id              NutonAdminApi.QaQuestionController :delete
``````

This is route in the parent route for the same entity.

``````      qa_question_path  GET   /api/v1/qa_questions                 NutonApi.QaQuestionController :index
qa_question_path  POST  /api/v1/qa_questions                 NutonApi.QaQuestionController :create
``````

Their path names are the same but their EP are different.
When I run following test case

`````` json_resp =
put(
conn,
qa_question_path(conn, :update, id),
params
)
|> json_response(200)
``````

It gives me this error:

``````   ** (ArgumentError) no action :update for ApiWeb.Router.Helpers.qa_question_path/3. The following actions/clauses are supported:

qa_question_path(conn_or_endpoint, :create, params \\ [])
qa_question_path(conn_or_endpoint, :index, params \\ [])
qa_question_path(conn_or_endpoint, :show, nuton_id, params \\ [])
``````

I understand the issue because of the same path names in both routes . It just checks if the path exist in the parent and raise an error, but how can I include child router in the test cases so that it will check if the path exist in it.
