Raynor-Chai

A chai extension which allows the use of raynor marshallers in assertions.

import * as chai from 'chai'
import { raynorChai } from 'raynor-chai'

class User {
    @MarshalWith(StringMarshaller)
    name: string;
    @MarshalWith(ArrayOf(IntegerMarshaller))
    scoresByDay: number[];

    totalScore(): number {
        return this.scoresByDay.reduce((a,b) => a + b, 0);
    }
}

chai.use(raynorChai);

const user = new User();
user.name = 'Raynor';
user.scoresByDay = [10, 20, 30];

chai.expect(user).to.be.raynor(new (MarshalFrom(User))()); // Assertion passes

const badUser = new User();
badUser.name = 'Raynor';
badUser.scoresByDay = [10, 20.5, 30];

chai.expect(badUSer).to.not.be.raynor(new (MarshalFrom(User))()); // Assertion passes
