Moq

This library provides macro that provides mock struct generating that implements trait.

toml [dependencies] moq = "0.1"

Usage example

```rust

[moq::automock]

trait Trait { fn func(&self, arg: i64) -> String; }

[test]

fn testok() { let mock = TraitMock::new() .expectcallfunc(|arg: i64| { asserteq!(arg, 42); format!("Hello, {}", arg) }) .expectcallfunc(|arg: i64| { assert_eq!(arg, -1); format!("Hello again, {}", -1) });

mock.func(42);
mock.func(-1);

}

[test]

fn testfailedextracall() { let mock = TraitMock::new() .expectcallfunc(|arg: i64| { asserteq!(arg, 42); format!("Hello, {}", arg) });

mock.func(42);
mock.func(-1); // Panic here

}

[test]

fn testfailedmissingcall() { let mock = TraitMock::new() .expectcallfunc(|arg: i64| { asserteq!(arg, 42); format!("Hello, {}", arg) }) .expectcallfunc(|arg: i64| { assert_eq!(arg, -1); format!("Hello again, {}", -1) });

mock.func(42);
// Panic here

} ```

async_trait also works, but the main limitation is to specify the automock macro above the async_trait ```rust

[moq::automock]

[asynctrait::asynctrait]

trait Trait { async fn func(&self, arg: i64) -> String; }

[test]

fn testok() { let mock = TraitMock::new() .expectcallfunc(|arg: i64| async { asserteq!(arg, 42); format!("Hello, {}", arg) });

mock.func(42).await;

} ```

You can find more examples in the tests.
