Cypress Based Perf Testing Suite for Admin (PoC)

[P0NDER0SA]

Summary | Résumé

This pull request introduces a dedicated performance testing suite for the Cypress end-to-end tests, enabling repeatable synthetic performance measurements against staging or PR review environments. It adds new Cypress commands and a performance smoke test, updates documentation, and provides a manual GitHub Actions workflow for running and summarizing performance checks.

Performance Testing Suite:

• Added a new performance smoke test (smoke.perf.cy.js) that measures admin journeys, page visits, and API request timings, and generates JSON artifacts for each run. The test also cleans up created templates to keep the environment tidy.
• Introduced new custom Cypress commands (startPerfCapture, measureVisit, trackRequestDuration, flushPerfArtifact) to capture and record detailed performance metrics, including per-page and per-request timings, and to write artifacts via a new writePerfArtifact task. [1] [2] [3]

Configuration and Workflow:

• Added a new GitHub Actions workflow (cypress-performance.yml) that allows manual triggering of performance checks, supports custom parameters (base URL, repeat count, spec), summarizes results, and uploads artifacts for review.
• Updated Cypress configuration to support new environment variables and the artifact writing task, and set sensible defaults for performance runs. [1] [2]

Developer Experience and Documentation:

• Updated README.md and package.json to document the new performance suite, explain usage, and add a perf:staging script for local runs. [1] [2]

These changes provide a robust framework for measuring and tracking performance regressions in admin journeys, both locally and in CI, without mixing performance data into main smoke test results.
