Translations Tests Laravel Package

Product Decisions This Supports

• Localization & i18n Roadmap: While this package is Symfony-specific, it inspires a Laravel-native solution to automate translation validation, reducing manual QA effort for multilingual features (e.g., e-commerce, SaaS platforms). Aligns with roadmap items like:
  • "Reduce translation bugs by 50% via automated testing" (via custom Laravel assertions).
  • "Standardize i18n testing across teams" (by providing a reusable test template).
• Quality Assurance (QA) Automation:
  • Build vs. Buy: Avoids reinventing translation validation from scratch. Instead of custom scripts, leverage a proven pattern (Symfony’s approach) adapted for Laravel.
  • CI/CD Integration: Enables pre-commit hooks or GitHub Actions to block broken translations early (e.g., missing keys, syntax errors).
• Developer Experience (DX):
  • Onboarding: New devs can instantly validate translations without deep knowledge of Laravel’s internals.
  • Consistency: Enforces uniform translation file structure (e.g., required keys, locale coverage).
• Cost Efficiency:
  • Low-Cost Alternative: A Laravel-adapted version could be built in <1 week (vs. months of custom tooling).
  • Maintenance Savings: Reuses Laravel’s testing ecosystem (Pest/PHPUnit) instead of Symfony dependencies.

When to Consider This Package

• Adopt if:

  • Your Laravel project heavily relies on translations (e.g., 10+ locales, frequent updates).
  • You lack automated translation validation and currently rely on manual reviews or ad-hoc scripts.
  • Your team uses PHPUnit/Pest and wants to standardize testing across modules (e.g., resources/lang/).
  • You’re willing to fork and adapt the package (or build a Laravel-native equivalent) to avoid Symfony dependencies.
  • Localization is a critical feature (e.g., global SaaS, multilingual CMS) where bugs are costly.

• Look Elsewhere if:

  • Your translations are static or rarely updated (manual checks suffice).
  • You use non-standard translation formats (e.g., XLIFF, PO files) or database-backed translations.
  • Your team prefers dedicated localization tools (e.g., Lokalise, Crowdin) for validation.
  • You cannot maintain Symfony dependencies (e.g., symfony/translation conflicts with Laravel’s system).
  • Existing Laravel tools (e.g., spatie/laravel-translation-loader, custom Pest assertions) already meet your needs.

How to Pitch It (Stakeholders)

For Executives: "We can automate 90% of translation validation in our Laravel app by adapting an open-source Symfony tool—saving 10+ hours/week in manual QA and reducing localization bugs by 40%. For a one-time investment of <1 week, this ensures every language file is error-free before release, critical for our [global market/enterprise clients]. The package is lightweight, and we’ll open-source our Laravel version to give back to the community."

For Engineering: *"This Symfony package solves a core problem: validating translation files for missing keys, syntax errors, and locale consistency. Here’s how we’d use it in Laravel:

• Fork the package and rewrite the file scanner to work with resources/lang/ (JSON/YAML) instead of Symfony’s structure.
• Replace Symfony’s Translation component with Laravel’s trans() helper for assertions.
• Integrate with Pest/PHPUnit for seamless testing (example below). Tradeoffs:
• Effort: 3–5 days to adapt (vs. building from scratch).
• Risk: Minimal—we’re not using Symfony, just borrowing the validation logic.
• Alternative: We could write custom tests, but this gives us proven, battle-tested code to start from.

Example Test Class (Proposed Laravel Adaptation):

// tests/TranslationTest.php
use Illuminate\Support\Facades\File;
use Pest\TestCase;

class TranslationTest extends TestCase {
    use \Craue\TranslationsTests\Traits\YamlTranslationValidator; // Hypothetical adapted trait

    protected function defineTranslationFiles(): array {
        return File::allFiles(app()->langPath())
            ->map(fn ($file) => $file->getPathname())
            ->toArray();
    }

    protected function defineDefaultLocale(): string {
        return config('app.locale');
    }
}

Why this works: We keep the same validation rules (e.g., required keys, no duplicate entries) but apply them to Laravel’s file structure."*

For Design/UX Teams: "This tool ensures every language string is accounted for—no more ‘missing translation’ errors in production. For example, it’ll flag if a key like auth.login.button is missing in French before we ship. This directly impacts user experience for non-English speakers."
