## Separando testes { #separating-tests }

Em uma aplicação real, você provavelmente teria seus testes em um arquivo diferente.

E sua aplicação **FastAPI** também pode ser composta de vários arquivos/módulos, etc.

### Arquivo da aplicação **FastAPI** { #fastapi-app-file }

    @Test
    void testSend() throws SmbException {
        SmbTree tree = new SmbTree(session, "testShare", "A:");
        tree.connectionState = 2; // Connected state
        tree.tid = 123;

        // Create real request and response objects since they're not interfaces
        ServerMessageBlock request = new SmbComOpenAndX("testfile.txt", 0x01, 0, null);
        ServerMessageBlock response = new SmbComOpenAndXResponse();

The supporting additional functions `fake_password_hasher` and `fake_save_user` are just to demo a possible flow of the data, but they of course are not providing any real security.
