/// tip

Notice that the testing functions are normal `def`, not `async def`.

And the calls to the client are also normal calls, not using `await`.

This allows you to use `pytest` directly without complications.

You could also use `from starlette.testclient import TestClient`.

Go 1.22 changed the default minimum TLS version supported by both servers
and clients to TLS 1.2. The default can be reverted to TLS 1.0 using the
[`tls10server` setting](/pkg/crypto/tls/#Config).

Go 1.22 changed the default TLS cipher suites used by clients and servers when
not explicitly configured, removing the cipher suites which used RSA based key

They will be converted to their corresponding values (strings in this case) before returning them to the client:

```Python hl_lines="18  21  23"

In your client you will get a JSON response like:

```JSON

  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
