Mocking traits with associated functions?

[U007D]

Given

#[cfg_attr(test, automock)]
pub trait ICmdRunner {
    fn run(cmd: Cmd, verbosity: Verbosity) -> Result<()>;
}

(note the lack of self parameter on .run().)

1. Can automock or mock! handle this?
2. What does the usage of MockICmdRunner look like? I tried:

[test]
// ...
    let cmd_runner = {
        let tmp_mock = MockICmdRunner::default();
        tmp_mock
            .expect_run() // in case `automock` made an `expect_run` method
            .times(1)
            .with(eq(expected_res), eq(verbosity))
            .returning(|_, _| Ok(()));
        tmp_mock
    };
// ...

and

[test]
// ...
    MockICmdRunner::expect_run().times(1).with(eq(expected_res), eq(verbosity)).returning(|_, _| Ok(()));  // in case `automock` made a static `expect_run()`
// ...

without success.

[`expect_run`] function or associated item not found in `MockICmdRunner`

See the example at https://docs.rs/mockall/latest/mockall/#static-methods . Because there's no receiver, the syntax is a little bit different.

Sorry, not sure how I missed this in my searching!

But yes, this makes perfect sense, thank you! 💯
