Data Layer Integrity Sentinel & E-Commerce Event QA CLI

Stop deploying broken tracking tags. Automatically validate dataLayer e-commerce event payloads in your CI/CD pipeline before release.

Problem it addresses

Develop a pure Python dataLayer integrity testing tool (datalayer_sentinel.py): 1) Validates JSON-LD and dataLayer payloads against GA4 standard schemas (view_item, add_to_cart, begin_checkout, purchase), 2) Checks for critical parameters (currency ISO code, value numeric type, item arrays, transaction_id uniqueness), 3) Emits clear pass/fail terminal reports and JSON summaries suitable for GitHub Actions CI/CD.

Who it is for

PRO operating in high-growth e-commerce, digital publishing, and direct-response marketing across Saudi Arabia, UAE, and Egypt.

How to evaluate and use it

  1. Read the README first and confirm that the documented problem matches your use case.
  2. Inspect the listed files to find the data, tools, templates, and tests relevant to your task.
  3. Follow the repository’s Quick Start and check prerequisites before running commands.
  4. Compare outputs with documented examples and review limitations before using them in a decision or client workflow.

Quick Start from the README: python -m unittest discover -s tests · python src/datalayer_sentinel.py --help

Scope and limitations

  • JSON Schema Validation: Validates client-side dataLayer.push payloads against strict schema contracts for standard e-commerce events.
  • Asynchronous Event Race Conditions: Detects when purchase or addToCart events push before user consent or container library initialization.
  • Automated CI/CD Quality Gate: Runs headless assertion tests during automated staging builds to prevent regressions during store checkout updates.

This page summarizes the available documentation; it does not establish performance or business results. Verify data and prerequisites before use.
