If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

        // When
        response.setupResponse(resp);

        // Then - nothing should happen (empty implementation)
        verifyNoInteractions(resp);
    }

    @DisplayName("Should read valid negotiate response from wire format")
    void testReadBytesWireFormatValid() throws Exception {
        // Given
        byte[] buffer = createValidNegotiateResponseBuffer();

        // When

        byte[] recv = new byte[16];
        int r = spyHandle.sendrecv(buf, 2, 4, recv, 16);

        // Assert
        assertEquals(7, r);
