Factori

A testing factory library for Rust, inspired by FactoryBot. 🤖 🦀

Factori works on stable Rust >=1.26. It aims to provide a clean, ergonomic syntax for instantiating test objects, without sacrificing type-safety.

Example

Factori provides two macros: factori!, which defines a factory for a type, and create! which instantiates it:

```rust // Factori's macros recurse a lot. You may need to tell the compiler to increase its macro // recursion limit. It should not affect run-time performance.

![recursion_limit="1024"]

[macro_use]

extern crate factori;

pub struct Vehicle { number_wheels: u8, electric: bool, }

factori!(Vehicle, { default { number_wheels: 4, electric: false, }

trait bike {
    number_wheels: 2,
}

});

fn main() { let default = create!(Vehicle); asserteq!(default.numberwheels, 4); assert_eq!(default.electric, false);

let three_wheels = create!(Vehicle, number_wheels: 3);
assert_eq!(three_wheels.number_wheels, 3);

let electric_bike = create!(Vehicle, :bike, electric: true);
assert_eq!(electric_bike.number_wheels, 2);
assert_eq!(electric_bike.electric, true);

} ```

More examples are available in the tests/ directory.

Stability

Factori is still brand new, and the syntax may change significantly between point-releases.

Testing

Run:

sh cargo test
