[feature request] support ui-cargo

[lengyijun]

Although we can compress all mods in one file, supporting ui-cargo make it easier to migrate tests from clippy

Hi, @lengyijun. Could you please point me to the project you'd like support for? Do you have a sense of the changes that would be required?

Currently the tests doesn't make sense:

If copy ui/fail.rs to seperate rust project, a warning is given as expected.

However, cargo test gave no error

Just to be sure I understand, when you say "support ui-cargo", you mean support testing entire packages simliar to how Clippy does with its ui-cargo tests? https://github.com/rust-lang/rust-clippy/tree/master/tests/ui-cargo
