Need at least one example using `main_binary` and/or `cargo_binary` to actually test a Rust CLI app.

The docs don't show how to test a cli application written in Rust.

Like, there are no examples in the documentation that actually show how to do this. The main_binary and cargo_binary functions are mentioned, but without showing how to use them to do anything useful.

If this crate main audience are Rust programmers wanting to test Rust CLI applications, having some examples showing how to test an actual Rust cli application would significantly lower the barrier of entry to use this crate.

Agreed, these functions need docs. I’ve been meaning to get back to this crate and the ongoing API refactor (I’m sorry I haven’t been around much, @epage!) and more detailed docs are most certainly on the list!

For now, though, do you have any concrete issues with these helpers? (The are just shortcuts for cargo run --.)
