Dto Tester Laravel Package
skrepr/dto-tester
A lightweight testing toolkit for Data Transfer Objects in Laravel and PHP projects. It helps you verify DTO construction, property mapping, serialization, and validation behavior with expressive assertions, so your DTOs stay predictable and reliable as your application grows.
skrepr/dto-tester is a lightweight testing utility for Data Transfer Objects in Laravel and PHP applications. It helps verify that DTOs correctly map input data, expose expected properties, and handle serialization, keeping your test suite readable and focused on behavior.
- Fluent assertions for DTO construction and property values
- Helpers for mapping, casting, and serialization checks
- Seamless PHPUnit and Pest integration
- Laravel-friendly setup with minimal configuration
- Reusable builders for consistent DTO test fixtures
Frequently asked questions about Dto Tester
- What is Skrepr DTO Tester and what problem does it solve?
- Skrepr DTO Tester is a lightweight Laravel/PHP package for testing data transfer objects with expressive assertions. It helps you validate DTO construction, property values, and transformations directly in your test suite. Instead of writing repetitive manual assertions, you can use it to make DTO tests quicker and more reliable.
- How do I install Skrepr DTO Tester in a Laravel app?
- Install it as a dev dependency with Composer, for example composer require --dev skrepr/dto-tester. Laravel packages often use package discovery, but confirm any service provider registration steps in the README. After installation, you can start adding assertions to your PHPUnit or Pest tests.
- Does Skrepr DTO Tester work with Pest as well as PHPUnit?
- The package is described as working within Laravel/PHP test suites, and its expressive assertions are intended for typical test runners such as PHPUnit and Pest. The exact supported runners are not specified in the provided context, so verify the README for integration examples. If your Laravel project uses Pest, you can generally call the same assertion helpers from Pest tests.
- What kinds of DTO assertions does Skrepr DTO Tester provide?
- It focuses on expressive assertions for DTO construction, properties, and transformations. That means you can verify that a DTO is built with expected values, that its properties match expectations, and that conversion or transformation output is correct. The exact assertion method names should be confirmed in the package README.
- Which Laravel and PHP versions are supported by Skrepr DTO Tester?
- The package is described as a Laravel/PHP package, but the exact Laravel and PHP version constraints live in its composer.json. Check those constraints or run composer show skrepr/dto-tester after installation. That will tell you whether it supports your application's Laravel and PHP versions.
- Do I need to configure anything after installing Skrepr DTO Tester?
- In many Laravel packages, installation is enough because service providers are auto-discovered. The provided context does not list required configuration steps, so check the README for any publishable config or setup. If no configuration is documented, you can begin using the assertions in your tests.
- Can I use Skrepr DTO Tester outside Laravel in a plain PHP project?
- It is described as a Laravel/PHP package, so it may work in standalone PHP projects if its dependencies allow it. However, its documented focus is testing DTOs in Laravel applications. Review the composer.json requirements before using it outside Laravel.
- How does Skrepr DTO Tester help test DTO transformations?
- It provides assertions aimed at validating DTO transformations, so you can confirm that input data is converted into the expected DTO state. This is useful when DTOs are created from requests, arrays, or other objects. Use the package's transformation assertions alongside construction and property checks for full coverage.
- Is Skrepr DTO Tester suitable for CI pipelines and production test suites?
- Yes, it is intended for test suites, so it fits naturally into CI pipelines that run PHPUnit or Pest. Because it is a testing helper, it should typically be installed as a dev dependency. Keep your DTO tests deterministic and run them on every build to catch regressions.
- How is Skrepr DTO Tester maintained and what alternatives exist?
- Maintenance status is not detailed in the provided context, so check Packagist and the repository for recent releases and open issues. Alternatives include custom PHPUnit assertions, spatie/laravel-data testing helpers, or broader DTO libraries. Choose based on how closely its assertion style matches your team's testing approach.
