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(),
        };
    }
}
