+### Functional tests
+
+The functional test suite uses [stabber](https://git.jabber.space/devs/stabber) as a mock XMPP server. Tests are located in `tests/functionaltests/`.
+
+#### Running functional tests
+
+Functional tests require stabber to be installed. Once installed, tests run as part of `make check`:
+
+```bash
+make check
+```
+
+#### Writing functional tests
+
+Use content-based stubbing with stabber:
+
+```c
+// Use stbbr_for_query for IQ queries (roster, disco, etc.)
+stbbr_for_query("jabber:iq:roster", "<iq type='result'>...</iq>");
+
+// Use stbbr_send for presence, message, and push-style stanzas
+stbbr_send("<presence from='buddy@localhost'>...</presence>");
+```
+
+Guidelines:
+
+1. Use `stbbr_for_query(namespace, xml)` for IQ queries where the namespace is stable.
+2. Use `stbbr_send(xml)` for presence, message, and other push-style stanzas.
+3. Keep assertions tolerant of ordering when possible; use `prof_output_regex()` for flexible matching.
+4. If timing issues appear, use `prof_timeout()` around critical expectations and reset afterwards.
