## Montando uma aplicação **FastAPI**

"Montar" significa adicionar uma aplicação completamente "independente" em um caminho específico, que então se encarrega de lidar com tudo sob esse caminho, com as operações de rota declaradas nessa sub-aplicação.

### Aplicação de nível superior

        // Execute on both instances
        dataStore1.store(config, callback, params);
        dataStore2.store(config, callback, params);
        dataStore2.store(config, callback, params);

        // Verify independent operation
        assertEquals(1, store1CallCount.get());
        assertEquals(2, store2CallCount.get());
    }

    // Test implementation of IndexUpdateCallback for testing purposes

        assertNull(pc.getPassword());
        verify(spyAuth, times(1)).getPasswordAsCharArray();
    }

    @Test
    @DisplayName("clone: copies fields and cached subject; instances are independent")
    void testCloneCopiesFieldsAndIndependence() throws Exception {
        // Use configuration-based constructor to also exercise copying of configuration/service fields

            assertEquals(type, iate.getType());
            assertEquals(message, e.getMessage());
        }
    }

    public void test_multipleExceptionInstances() {
        // Test multiple instances are independent
        InvalidAccessTokenException exception1 = new InvalidAccessTokenException("Type1", "Message1");
        InvalidAccessTokenException exception2 = new InvalidAccessTokenException("Type2", "Message2");

        SmbNegotiation anotherNegotiation =
                new SmbNegotiation(anotherRequest, anotherResponse, anotherRequestBuffer, anotherResponseBuffer);

        // Verify the instances are independent
        assertNotSame(negotiation.getRequest(), anotherNegotiation.getRequest());
        assertNotSame(negotiation.getResponse(), anotherNegotiation.getResponse());

That's what we'll solve, let's load the model before the requests are handled, but only right before the application starts receiving requests, not while  the code is being loaded.
