## Criar o App com um Único Modelo { #create-the-app-with-a-single-model }

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

Depois, vamos melhorá-lo aumentando a segurança e versatilidade com **múltiplos modelos** abaixo. 🤓

### Criar Modelos { #create-models }

Importe o `SQLModel` e crie um modelo de banco de dados:

        // Since we can't directly verify the internal state, we create a new request to test
        Smb2CloseRequest newRequest = new Smb2CloseRequest(mockConfig, testFileId);
        assertNotNull(newRequest, "Should create request with new file ID");
    }

    @Test
    @DisplayName("Should handle null file ID")
    void testSetNullFileId() {

        v.add(new DERTaggedObject(true, 2, new DERBitString(new byte[] { 0x01 })));

        // Create a custom APPLICATION tagged object that throws IOException when encoding
        // We need to create a proper ASN1TaggedObject with APPLICATION tag class
        // Create a custom base object that throws IOException
        ASN1Encodable badBase = new ASN1Encodable() {
            @Override

        // Configure OEM encoding to avoid NullPointerException
        when(mockConfig.getOemEncoding()).thenReturn("UTF-8");
    }

    @Test
    @DisplayName("Constructor with Configuration only should create empty Name instances")
    void testConstructorWithConfigOnly() {
        SessionRequestPacket packet = new SessionRequestPacket(mockConfig);

        assertNotNull(packet);

        // Create mock HTTP handler
        URLStreamHandler httpHandler = new URLStreamHandler() {
            @Override
            protected URLConnection openConnection(URL u) throws IOException {
                return mock(HttpURLConnection.class);
            }
        };

        // Create mock HTTPS handler
        URLStreamHandler httpsHandler = new URLStreamHandler() {

    populate(table, data);
    return table;
  }

  public void testRowKeySetOrdering() {
    table = create("foo", 3, 'a', "bar", 1, 'b', "foo", 2, 'c');
    assertThat(table.rowKeySet()).containsExactly("foo", "bar").inOrder();
  }

  public void testRowOrdering() {
    table = create("foo", 3, 'a', "bar", 1, 'b', "foo", 2, 'c');
    assertThat(table.row("foo").keySet()).containsExactly(2, 3).inOrder();
  }

                "/invoices/": {
                    "post": {
                        "summary": "Create Invoice",
