## `Depends()`

Dependencies are handled mainly with the special function `Depends()` that takes a callable.

Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

        return asListHtml();
    }

    /**
     * Performs a search operation with the provided form data.
     *
     * @param form the list form containing search criteria
     * @return HTML response with search results
     */
    protected HtmlResponse doSearch(final ListForm form) {
        validate(form, messages -> {}, this::asListHtml);

        // Test with no bad words
        String[] badWords = { "spam", "illegal" };
        assertFalse(item.isBadWord(badWords));

        // Test with matching bad word
        String[] badWords2 = { "test", "bad" };
        assertTrue(item.isBadWord(badWords2));

        // Test with partial match
        item.setText("testing something");

# Testing Events: lifespan and startup - shutdown { #testing-events-lifespan-and-startup-shutdown }

When you need `lifespan` to run in your tests, you can use the `TestClient` with a `with` statement:

{* ../../docs_src/app_testing/tutorial004.py hl[9:15,18,27:28,30:32,41:43] *}


You can read more details about the ["Running lifespan in tests in the official Starlette documentation site."](https://www.starlette.io/lifespan/#running-lifespan-in-tests)
