So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

would result in something equivalent to:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",

async with lifespan(app):
    await do_stuff()
```

When you create a context manager or an async context manager like above, what it does is that, before entering the `with` block, it will execute the code before the `yield`, and after exiting the `with` block, it will execute the code after the `yield`.

In our code example above, we don't use it directly, but we pass it to FastAPI for it to use it.

This project should only be used by :testing-jvm-infrastructure, however it is not depended upon directly.
Instead :testing-jvm-infrastructure loads classes from this project via reflection due to the above noted Java version issue.
We make sure to include this subproject as a runtime dependency in :distributions-core to ensure we include it with the Gradle distribution.
