### Other utility functions { #other-utility-functions }

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.

This is in contrast to the functions that FastAPI calls for you: *path operation functions* and dependencies.

                throw new RuntimeException("Delete operation failed");
            }
        };
        ComponentUtil.register(searchEngineClient, "searchEngineClient");

        // Execute the job
        String result = purgeDocJob.execute();

        // Assert error message is in the result
        assertTrue(result.contains("Delete operation failed"));
        assertTrue(result.endsWith("\n"));
    }

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

So, in OpenAPI, each of the HTTP methods is called an "operation".

We are going to call them "**operations**" too.
