Example

Any model

export class User {

    name: string

    age: number

    Addresss: string
}

The Fixture (path test/fixture/UserFixture.ts)

import { FixtureBuilder } from "roit-test-helper";
import { TemplateLoader } from "roit-test-helper";
import { User } from "../model/User";

export class UserFixture implements TemplateLoader {

    load(): void {
        
        FixtureBuilder.add<User>('USER_FIXTURE_1', {
            Addresss: 'Address 1',
            age: 40,
            name: 'Maria'
        })

        FixtureBuilder.add<User>('USER_FIXTURE_2', {
            Addresss: 'Address 2',
            age: 40,
            name: 'Maria'
        })
    }

}

Register Template Loader (path test/fixture/index.ts)

import { TemplateInstance } from "roit-test-helper";
import { UserFixture } from "./UserFixture";

TemplateInstance.registerTemplateLoader([
    new UserFixture,
    ...
])

Get fixture

import { TemplateInstance } from "roit-test-helper";

it('user fixture 1 test', async () => {

    const user = TemplateInstance.getFixture<User>('USER_FIXTURE_1')

    expect(user?.name).toBe("Maria")
    expect(user?.Addresss).toBe("Address 1")
    expect(user?.age).toBe(40)
});
