stub_trait

Macro to implement stub object for a trait.

Overview

Stub traits is a technique to simulate some comportments or to avoid to be blocked by a specific part of the code that is not implemented yet.

Usage

stub_trait is generally only used by tests. Add the following snippet into your Cargo.toml: toml [dev-dependencies] stub_trait = "0.1.0"

You can use it like this: ```rust

[cfg(test)]

use stub_trait::stub;

[cfg_attr(test, stub)]

trait Animal { fn name(&self) -> &str; }

[cfg(test)]

mod test { use super::*;

#[test]
fn stub_all_calls() {
    let mut animal = StubAnimal::default();
    animal.stub_all_calls_of_name(|| "Ivana");
    assert_eq!(animal.name(), "Ivana");
    assert_eq!(animal.name(), "Ivana");
    assert_eq!(animal.count_calls_of_name(), 2);
}

#[test]
fn stub_call_by_call() {
    let mut animal = StubAnimal::default();
    animal.register_stub_of_name(|| "Ivana");
    animal.register_stub_of_name(|| "Truffle");
    assert_eq!(animal.name(), "Ivana");
    assert_eq!(animal.name(), "Truffle");
    assert_eq!(animal.count_calls_of_name(), 2);
}

} ```
