### Testing an example with `assume-role.go`

The included program in this directory can also be used for testing:

``` shell
$ go run assume-role.go -u foobar -p foo12345 -d

You could still use most of the features in **FastAPI** with the knowledge from the main [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank}.

The next sections are **not necessarily "advanced"**.

And it's possible that for your use case, the solution is in one of them.
