### Async Context Manager

Si revisas, la función está decorada con un `@asynccontextmanager`.

Eso convierte a la función en algo llamado un "**async context manager**".

{* ../../docs_src/events/tutorial003.py hl[1,13] *}

Un **context manager** en Python es algo que puedes usar en una declaración `with`, por ejemplo, `open()` puede ser usado como un context manager:

```Python

            when(resource.getContext()).thenReturn(mockContext);

            // When
            CIFSContext context = resource.getContext();

            // Then
            assertNotNull(context, "Context should not be null");
            assertSame(mockContext, context, "Should return the expected context");
        }

        @Test
        @DisplayName("getName should return resource name")

     * @return session instance with the given type
     */
    <T extends SmbSession> T unwrap(Class<T> type);

     *
     * @return the context this session is attached to

    CIFSContext getContext();
