## A database dependency with `yield`

For example, you could use this to create a database session and close it after finishing.

Only the code prior to and including the `yield` statement is executed before creating a response:

```Python hl_lines="2-4"
{!../../../docs_src/dependencies/tutorial007.py!}
```

The yielded value is what is injected into *path operations* and other dependencies:

          }
        });

    // Run those tasks together.
    fakePool.runAll();

    // Check that the interruption of a SequentialExecutor's task is restored to the thread once
    // it is yielded. Clear the bit while checking so that the test doesn't hose JUnit or some other
    // test case.
    assertThat(Thread.interrupted()).isTrue();
  }

  public void testInterrupt_doesNotStopExecution() {

  at the final moment when it yielded the logical processor, for example
  because it made a system call or tried to acquire a mutex.

  Directly underneath each bar, a smaller bar or more commonly a fine
  vertical line indicates an event occurring during its execution.
  Some of these are related to garbage collection; most indicate that
  a goroutine yielded its logical processor but then immediately resumed execution

          }
        });
