Laminas Cache Storage Adapter Test Laravel Package

Product Decisions This Supports

• Standardizing Cache Adapter Testing: Adopt this package to ensure consistent, reliable, and maintainable test suites for all custom or third-party laminas-cache adapters (e.g., Redis, Memcached, filesystem). Eliminates reinventing test logic for core cache operations (TTL, eviction, serialization).
• Accelerating Development Velocity: Reduces time spent writing/debugging adapter-specific tests by leveraging pre-built, battle-tested assertions (e.g., expiry handling, key validation). Ideal for teams building multiple cache backends (e.g., hybrid caching strategies).
• Compliance with PSR Standards: Aligns with PSR-6/PSR-16 by providing integration tests for both interfaces, ensuring compatibility with modern PHP ecosystems (e.g., Symfony, Laravel via laminas/laminas-cache).
• Roadmap for Scalability: Enables "build vs. buy" decisions for custom cache adapters—use this package to validate new adapters before committing to full development. Example: Testing a custom S3 adapter before production rollout.
• Use Cases:
  • Open-Source Contributions: Maintainers of laminas-cache adapters (e.g., laminas-cache-redis) can reuse these tests to ensure backward compatibility.
  • Enterprise Caching Layers: Validate custom cache backends (e.g., database-based caching) against industry standards.
  • CI/CD Pipelines: Integrate into test suites to gate cache-related PRs (e.g., "No PR merges without passing adapter tests").

When to Consider This Package

• Adopt When:

  • Your project uses laminas/laminas-cache v3+ or PSR-6/PSR-16 cache adapters** and needs standardized test coverage.
  • You’re developing multiple cache backends (e.g., Redis, APCu, filesystem) and want to avoid duplicating test logic.
  • Your team prioritizes test-driven development (TDD) for caching layers, especially for expiry, serialization, or key validation.
  • You require PHP 8.0+ compatibility and support for modern testing frameworks (e.g., PHPUnit 10+).

• Look Elsewhere When:

  • You’re using non-Laminas cache libraries (e.g., Symfony Cache, Predis) without laminas-cache integration.
  • Your cache layer is proprietary or vendor-locked (e.g., a custom in-memory cache) with no need for PSR compliance.
  • You lack PHPUnit in your test suite (this package is PHPUnit-centric).
  • Your project is PHP 7.3 or older (minimum PHP 7.4 required).
  • You need performance benchmarking (this focuses on correctness, not speed).

How to Pitch It (Stakeholders)

For Executives:

"This package lets us reduce technical debt in our caching layer by standardizing how we test cache adapters—whether Redis, Memcached, or custom solutions. It’s like having a ‘golden test suite’ for all cache backends, ensuring reliability without reinventing the wheel. For example, if we’re evaluating a new cache provider or building a hybrid system, this cuts testing time by 30–50% while improving consistency. It’s a low-risk, high-reward investment for scalability."

For Engineering Teams:

*"If you’re working on any cache adapter (even a one-off solution), this package gives you:

• Pre-built tests for core cache operations (TTL, eviction, serialization) that you’d otherwise write manually.
• PSR-6/PSR-16 compliance out of the box, so your adapters work seamlessly with modern frameworks.
• Future-proofing: Supports PHP 8.3, PHPUnit 10, and laminas-cache v4, so you won’t need to rewrite tests later. Install it as a dev dependency (composer require --dev laminas/laminas-cache-storage-adapter-test), extend the abstract test classes, and instantly get robust test coverage for your adapter."

For Developers:

"Need to test a custom cache adapter? Instead of writing boilerplate tests for getItem(), setItem(), or expiry logic, extend AbstractCacheItemPoolIntegrationTest or `AbstractSimpleCacheIntegrationTest. It handles edge cases like:

• Key length validation.
• Expiry timing (with a sleep timer to speed up tests).
• Type safety for keys/values. Just focus on your adapter’s unique logic—this package covers the rest. Example:

use Laminas\Cache\Storage\Adapter\Test\AbstractCacheItemPoolIntegrationTest;

class MyRedisAdapterTest extends AbstractCacheItemPoolIntegrationTest {
    protected function createCachePool(): CacheItemPoolInterface {
        return new MyRedisAdapter();
    }
}
```"
