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

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

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

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

The code following the `yield` statement is executed after the response:

    /** {@literal true} if the iterator has more elements. */
    protected boolean hasNext = true;

    /**
     * Returns an {@link Iterable} that wraps a {@link SingleValueIterator} for use in a for-each statement.
     *
     * @param <E> the element type
     * @param value the single value returned by the iterator
     * @return an {@link Iterable} wrapping a {@link SingleValueIterator}
     */

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

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}
