What's the procedure for mocking structs? - eviltoast

I know there’s mockall which seems to be geared towards implementation methods and traits, but I’m wondering about just structs with non-function properties.

In my tests, I want to define initialized structs with values. It works fine to just do it like I normally would in code, but I’m wondering if there’s more to it than that. Like if I have a cat struct:

struct Cat { name : String } `

#[cfg(test)] pub mod test { use super::Cat; fn test_create_cat() -> Cat { Cat { name. : String::from("Fred") }; }

That’s fine, but should I be doing it differently? What about mockall, is it not meant for structs with properties?

    A few days later, but keep in mind that if you write your tests in the module you declare your structs, you’ll have access to its “private” (non-pub) members since those are technically module scoped (default scope is pub(self)).

    pub struct Cat {
        name: String,
    }
    
    #[cfg(test)]
    mod tests {
        use super::*;
    
        #[test]
        fn create_cat() {
            let cat = Cat {
                name: "fluffy".into(),
            };
        }
    }
