cargo new by default creates a package with a main binary target, so no unit tests for it. If you run cargo new --lib it does create a unit test for the new “library” package. Cargo tries to put a proper amount of code of a new project.

Do you have any thought on what a unit test should look like in a package with a binary target?

In the meantime, you could take a look at some cargo extensions from crates.io, like cargo-generate which does project customizations.

For further discussion of creating a new package from pre-defined templates, please see #5151.
