+### Request/Response Debug Output
+
+Each test module supports a dedicated environment variable that enables pretty-printed JSON logging of every request and response:
+
+| Test file | Variable | Prints |
+|-----------|----------|--------|
+| `test_electrum.py` | `ELECTRUM_DEBUG=1` | `>>>` JSON-RPC payload / `<<<` response with elapsed time |
+| `test_native.py` | `NATIVE_DEBUG=1` | `>>> GET <url>` / `<<<` response JSON with elapsed time |
+| `test_bitcoind_rpc.py` | `BITCOIND_DEBUG=1` | `>>>` JSON-RPC payload / `<<<` response with elapsed time |
+
+```bash
+# Electrum — pretty-print all requests and responses
+ELECTRUM_DEBUG=1 pytest test_electrum.py -s
+
+# Native REST
+NATIVE_DEBUG=1 pytest test_native.py -s
+
+# bitcoind RPC
+BITCOIND_DEBUG=1 pytest test_bitcoind_rpc.py -s
+
+# Combine with -k to focus on a single test
+ELECTRUM_DEBUG=1 pytest test_electrum.py -s -k "block_headers_20000"
+```
+
+> **Note:** Use `-s` (or `--capture=no`) together with the debug variable so pytest does not suppress stdout.
