If you have dependencies with `yield`, the exit code will run *after* the middleware.

If there were any background tasks (covered in the [Background Tasks](background-tasks.md) section, you will see it later), they will run *after* all the middleware.

@test "No duplicate files on Windows" {
    cat <<EOF
Please rename files so there are no repeats. For example, README.md and
Readme.md would be the same file on Windows. In this test, you would get a
warning for "readme.md" because it makes everything lowercase. There are
repeats of these filename(s) with different casing:
EOF
    find . | tr '[A-Z]' '[a-z]' | sort | uniq -d | tee $BATS_FILE_TMPDIR/repeats

Because of this, **FastAPI** itself provides an alternative API documentation (using ReDoc), which you can access at [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc):

The same way, there are many compatible tools. Including code generation tools for many languages.

## More information about OpenAPI responses { #more-information-about-openapi-responses }

To see what exactly you can include in the responses, you can check these sections in the OpenAPI specification:

These **"type hints"** or annotations are a special syntax that allow declaring the <dfn title="for example: str, int, float, bool">type</dfn> of a variable.

By declaring types for your variables, editors and tools can give you better support.

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.
