Hi,

Symfony has infrastructure to start a test HTTP server process. With #50814 it can now specify your working directory.

It would be nice if all configured HTTP clients are proxied/routed to this test server 'when at test env' (when@test), thus without changing any request URL or so.

We'd ensure no external traffic occurs by default, unless a client opts-out for reasons. I recently discovered we fetch some external Soap WSDLs lazily (if not cached).

Mocking the endpoint should be effortless: match request => provide response, be done. This can now be achieved by leveraging some designated working directory (tests/Fixtures/Http/), to be fed to TestHttpServer::start(), to be triggered by FrameworkBundle::boot() or so.

In practice it would look like:

when@test:
  http_test_server:
    enabled: true
    port: 1337
    excluded_clients: []
    working_dir: 'tests/Fixtures/Http'

(eg. to be provided in at the recipe level)

The remaining question would be how we arrange tests/Fixtures/Http and write actual fixtures. Perhaps we can benefit from existing response classes to provide a mock.

# tests/Fixtures/Http/domain.com.php

return fn(Request $r): Response {
};

Thoughts?

Example

No response
