Php Sdk Laravel Package

Getting Started

• Install as a development dependency and pin it: composer require --dev volt-test/php-sdk. Confirm the installed version with composer show volt-test/php-sdk.
• Look first at the package README, CHANGELOG, src/, and any examples/ or tests/ directory. Check composer.json for Laravel auto-discovery, a service provider, config publishing, and supported PHP/Laravel versions.
• If the package ships Laravel integration, publish its config and keep environment-specific values out of code:

  php artisan vendor:publish --tag=volt-test-config
  

  Configure VOLT_TEST_BASE_URL, credentials, default users/duration, and thresholds in .env.staging or .env.testing. If there is no config file, create a small app-level config wrapper and bind the SDK client in a service provider.
• First use case: a staging-only smoke load test for /up and the login flow, run from a dedicated Artisan command or isolated Pest/PHPUnit group. Start with a small number of virtual users and a short duration, assert HTTP status and error rate, and print a compact result summary. Use this before releases rather than in the default unit-test suite.
• Where to look next: the SDK’s scenario definition API, runner/execution API, result/report API, and any hooks or custom reporter interfaces. These determine how much of the package you can integrate without coupling application code to vendor classes.

Implementation Patterns

• Dedicated performance entry point. Wrap the SDK in an Artisan command such as app/Console/Commands/VoltSmoke.php or a separate test suite tagged performance. Keep it out of the normal php artisan test path:

  php artisan volt:smoke --env=staging --users=10 --duration=30s
  

• Config-driven scenarios. Put target URLs, auth settings, thresholds, and test data sources in config/env. Avoid hardcoding staging URLs or credentials in scenario files.
• One scenario per critical journey. Model health checks, login, checkout, and key API endpoints separately. Use Laravel factories/seeders or API setup calls to create isolated data, then clean up after the run.
• Authenticate realistically. Bootstrap a token or session once per virtual user or reuse tokens where the SDK supports it. Handle token expiry and refresh explicitly; do not log in on every request unless that is the behavior being tested.
• Assert performance budgets. Fail the command or CI job when error rate, p95/p99 latency, or throughput crosses configured thresholds. Return a non-zero exit code so CI can enforce the budget.
• Use two CI profiles. Run a short smoke test on pull requests against staging, and a longer scheduled profile nightly or weekly. Publish JSON/JUnit artifacts and compare against a stored baseline rather than relying only on absolute numbers.
• Test a production-like target. Enable OPcache, cache, queue workers, and realistic middleware on staging. Disable Telescope, Debugbar, and verbose logging on the target because they distort results.
• Isolate the SDK behind an app service. Wrap scenario creation and result parsing in an application service so a future SDK upgrade or replacement does not leak vendor APIs throughout the codebase.
• Correlate with observability. Run tests in a known time window and compare results with Laravel logs, APM traces, database metrics, and queue depth. The SDK tells you response behavior; infrastructure metrics explain why.

Gotchas and Tips

• Repository metadata is missing. The assessment lists no repository, so verify the actual source, issue tracker, CI status, maintainer activity, and release tags before adopting. The release date metadata also looks anomalous; confirm the real tag and changelog. Pin an exact version.
• Keep it dev-only. Do not ship the SDK or its configuration to production unless the package explicitly requires a runtime component.
• Never load-test production by default. WAFs, rate limits, and shared infrastructure can turn a test into an incident. Use staging or an isolated environment with approval.
• Laravel config caching can hide changes. After changing env values, run php artisan config:clear or rebuild the config cache. A stale cached config is a common source of “it tested the wrong URL” bugs.
• Debug mode distorts results. APP_DEBUG=true, query logging, Telescope, and Debugbar add overhead. Match the target’s production configuration as closely as possible.
• Auth and CSRF are frequent failures. API tokens, session cookies, CSRF middleware, and token expiry can produce misleading 401/419 results. Validate the auth path with a single-user run before increasing load.
• Infrastructure often saturates first. PHP-FPM worker limits, database connection limits, Redis, and queue workers may become the bottleneck. Record server-side metrics alongside SDK results.
• Control test data growth. Load tests can create large numbers of users, orders, or log rows. Use idempotent endpoints where possible and clean up test data deterministically.
• CI runners are noisy. Shared runners, cold starts, and limited network bandwidth skew latency. Use a consistent runner size/region for baselines and avoid comparing runs from different environments.
• Retries and timeouts can mask failures. Record timeout and retry counts, not just successful responses. A low error rate with high retry volume is still a regression.
• Use extension points sparingly. Custom data providers, hooks, and reporters are useful, but keep them in application code rather than patching vendor files. Start with a tiny health-check spike; if the package lacks documentation or tests, measure maintenance risk before expanding usage.
