A parte mais importante é que quando você chama `python`, esse é exatamente o "`python`" que será executado.

Assim, você pode confirmar se está no ambiente virtual correto.

/// tip | Dica

É fácil ativar um ambiente virtual, obter um Python e então **ir para outro projeto**.

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

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

Digamos que você tenha uma estrutura de arquivo conforme descrito em [Aplicações maiores](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

No arquivo `main.py` você tem sua aplicação **FastAPI**:

  private val forbiddenLocks = mutableListOf<Any>()

  /** The timestamp of the last taken event, used to measure elapsed time between events. */
  private var lastTimestampNs: Long? = null

  /** Confirm that the thread does not hold a lock on `lock` during the callback. */
  fun forbidLock(lock: Any) {
    forbiddenLocks.add(lock)
  }

  /**

      assertThat(response.code).isEqualTo(200)
      assertThat(response.socket).isNull()
      assertThat(response.body.string()).isEqualTo("normal request")
    }
    // Confirm there's no RequestBodyStart/RequestBodyEnd on failed upgrades.
    assertThat(eventRecorder.recordedEventTypes()).containsExactly(
      CallStart::class,
      ProxySelectStart::class,
      ProxySelectEnd::class,

    }

    @Test
    public void test_serializable() {
        // Test that the exception has serialVersionUID
        WebApiException exception = new WebApiException(404, "Not Found");

        // This test confirms the exception can be created and has standard exception properties
        assertNotNull(exception);
        assertTrue(exception instanceof java.io.Serializable);
    }

    @Test

        file("/build/restResources/yamlTests/rest-api-spec/test/" + coreTest).exists()
        file("/build/restResources/yamlTests/rest-api-spec/test/" + xpackTest).exists()

        // confirm that replacement happened
        file("/build/restResources/yamlTests/rest-api-spec/test/" + coreTest).getText("UTF-8") == "replacedWithValue"

        when:
        result = gradleRunner("copyRestApiSpecsTask").build()

Cela confirme que vous parvenez à servir des fichiers statiques depuis votre application et que vous avez placé les fichiers statiques des docs au bon endroit.

    for (int i = 0; i < times; i++) {
      waitingThread.interrupt();
    }

    future.set(RESULT);

    assertEquals(times > 0, (boolean) interruptReporter.get(20, SECONDS));
  }

     */
    ExecutionException fromRunInterruptibly =
