But when checking benchmarks and comparisons you should keep the following in mind.

When you check the benchmarks, it is common to see several tools of different types compared as equivalent.

Specifically, to see Uvicorn, Starlette and FastAPI compared together (among many other tools).

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.

This is the equivalent to:

Notice the `.` at the end, it's equivalent to `./`, it tells Docker the directory to use to build the container image.

In this case, it's the same current directory (`.`).
