Spoken languages

The language chosen for Gherkin should be the same language users and domain experts use when they talk about the domain. Translating between two languages should be avoided.

This is why Gherkin has been translated to over 70 languages.

A # language: header on the first line of a .feature file tells Cucumber which spoken language to use (for example, # language: fr for French). If you omit this header, Cucumber will default to English (en).

# language: no

Egenskap: Dyr egenskap

  Scenario: Hvis vi mater en sulten katt, vil den ikke lenger være sulten
    Gitt en sulten katt
    Når jeg mater katten
    Så katten er ikke sulten

extern crate cucumber;
extern crate tokio;

use cucumber::{given, then, when, World};

#[derive(Debug, Default)]
struct Cat {
    pub hungry: bool,
}

impl Cat {
    fn feed(&mut self) {
        self.hungry = false;
    }
}

#[derive(Debug, Default, World)]
pub struct AnimalWorld {
    cat: Cat,
}

#[given(regex = r"^en (sulten|mett) katt$")]
async fn hungry_cat(world: &mut AnimalWorld, state: String) {
    match state.as_str() {
        "sulten" => world.cat.hungry = true,
        "mett" => world.cat.hungry = false,
        _ => unreachable!(),
    }
}

#[when("jeg mater katten")]
async fn feed_cat(world: &mut AnimalWorld) {
    world.cat.feed();
}

#[then("katten er ikke sulten")]
async fn cat_is_fed(world: &mut AnimalWorld) {
    assert!(!world.cat.hungry);
}

#[tokio::main]
async fn main() {
    AnimalWorld::run("tests/features/book/writing/languages.feature").await;
}

TIP: In case most of your .feature files aren't written in English and you want to avoid endless # language: comments, use Cucumber::language() method to override the default language globally.
