# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

        "EffectivelyPrivate", // It is still useful to distinguish between public interface and implementation details of inner classes even though it isn't enforced.

        "InlineMeSuggester", // Only suppression seems to actually "fix" this, so make it global

#### Secure Erasure and Locking

The MinIO server requires an available KMS to en/decrypt SSE-S3 encrypted objects. Therefore it is possible to erase or lock some or all encrypted objects. For example in case of a detected attack or other emergency situations the following actions can be taken:

    // Run a task that expects that it is not interrupted while it is running.
    e.execute(() -> assertThat(Thread.currentThread().isInterrupted()).isFalse());

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

    // Check that the interruption of a SequentialExecutor's task is restored to the thread once

        // Create a ServletException with a message
        String errorMessage = "Test servlet error message";
        ServletException servletException = new ServletException(errorMessage);

        // Wrap it in ServletRuntimeException
        ServletRuntimeException runtimeException = new ServletRuntimeException(servletException);

        // Verify that the cause is correctly set
        assertNotNull(runtimeException);
