rok-orm-factory

Model factories for generating test data. Define factories for your rok models and use them in tests or seeders with realistic fake data.

Installation

[dev-dependencies]
rok-orm-factory = { version = "0.1" }

Quick Start

use rok_orm_factory::{Factory, Faker};

pub struct UserFactory;

impl Factory for UserFactory {
    type Model = User;

    fn build(&self) -> User {
        User {
            id: 0,  // auto-assigned by DB
            email: Faker::email(),
            name: Faker::name(),
            password: "$argon2...".into(),  // pre-hashed test password
            created_at: chrono::Utc::now(),
        }
    }
}

// In tests
#[tokio::test]
async fn test_something() {
    let user = UserFactory.create(&pool).await?;
    let users = UserFactory.count(10).create_many(&pool).await?;
}

Faker Helpers

Faker::email()          // "user_142@example.com"
Faker::name()           // "Alice Johnson"
Faker::uuid()           // UUID v4 string
Faker::word()           // random word
Faker::sentence()       // random sentence
Faker::paragraph()      // random paragraph
Faker::number(1..=100)  // random number in range
Faker::bool()           // true or false
Faker::url()            // "https://example.com/path"
Faker::phone()          // "+1-555-0142"

With Overrides

let admin = UserFactory.with(|u| {
    u.role = "admin".into();
    u.email = "admin@example.com".into();
}).create(&pool).await?;

Relationships

let post = PostFactory.for_user(&user).create(&pool).await?;
// sets post.user_id = user.id
