mockalization_generator

Code generator for Mockalization. This package processes @Mockalization-annotated classes and generates extension-based mock data factories.

This package should be added as a dev_dependency. It is only used during code generation and not at runtime.

Installation

dependencies:
  mockalization_factory: ^2.0.0

dev_dependencies:
  build_runner: ^2.4.11
  mockalization_generator: ^2.0.0

Usage

1. Annotate your class with @Mockalization() (from mockalization_factory):

import 'package:mockalization_factory/mockalization_factory.dart';

part 'user.g.dart';

@Mockalization()
class User {
  @MockProperty(format: MockFormat.email)
  final String email;
  final int age;
  User({required this.email, required this.age});
}

2. Run the generator:

dart run build_runner build --delete-conflicting-outputs

3. Use the generated extension:

final user = UserMock.fake();
final users = UserMock.fakeList(10);

What Gets Generated

For each @Mockalization class, an extension is generated:

extension UserMock on User {
  static User fake() {
    final faker = Faker();
    return User(
      email: faker.internet.email(),
      age: faker.randomGenerator.integer(9999, min: 0),
    );
  }

  static List<User> fakeList(int length) {
    return List.generate(length, (_) => fake());
  }
}

Features

• Supports 20+ Dart types including primitives, collections, enums, and custom classes
• Nullable fields generate null or value randomly
• Nested generics (Map<String, List<int>>) fully supported
• Inheritance support (parent class fields included)
• 33 MockFormat options for realistic data
