From c8ac2cb60917d030bd81dc4fe32246a603dde788 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 26 Dec 2025 09:35:07 +0000 Subject: [PATCH] Add dynamic pricing E2E test suite with Playwright Implement comprehensive E2E tests to validate the surge pricing pipeline: - Test SimpleSurgePricer with configurable thresholds (high=3, surge=1.5x) - Verify discount pricing when demand is below low_threshold - Test multi-product differential pricing based on demand signals - Validate price propagation from pipeline through Redis to API Test infrastructure: - Playwright configuration with custom fixtures - Python pipeline worker for direct test execution (bypasses Airflow) - API client for event ingestion and price verification - Event generator for creating realistic interaction sequences - docker-compose.e2e.yml with minimal services for testing --- docker-compose.e2e.yml | 161 ++++++++++ e2e/README.md | 255 +++++++++++++++ e2e/global-setup.ts | 47 +++ e2e/global-teardown.ts | 10 + e2e/lib/api-client.ts | 191 ++++++++++++ e2e/lib/event-generator.ts | 249 +++++++++++++++ e2e/lib/fixtures.ts | 143 +++++++++ e2e/lib/index.ts | 6 + e2e/lib/pipeline-runner.ts | 152 +++++++++ e2e/lib/pipeline-worker.py | 245 +++++++++++++++ e2e/package.json | 27 ++ e2e/playwright.config.ts | 84 +++++ e2e/tests/dynamic-pricing.spec.ts | 497 ++++++++++++++++++++++++++++++ e2e/tsconfig.json | 28 ++ 14 files changed, 2095 insertions(+) create mode 100644 docker-compose.e2e.yml create mode 100644 e2e/README.md create mode 100644 e2e/global-setup.ts create mode 100644 e2e/global-teardown.ts create mode 100644 e2e/lib/api-client.ts create mode 100644 e2e/lib/event-generator.ts create mode 100644 e2e/lib/fixtures.ts create mode 100644 e2e/lib/index.ts create mode 100644 e2e/lib/pipeline-runner.ts create mode 100644 e2e/lib/pipeline-worker.py create mode 100644 e2e/package.json create mode 100644 e2e/playwright.config.ts create mode 100644 e2e/tests/dynamic-pricing.spec.ts create mode 100644 e2e/tsconfig.json diff --git a/docker-compose.e2e.yml b/docker-compose.e2e.yml new file mode 100644 index 0000000..1ac9c3f --- /dev/null +++ b/docker-compose.e2e.yml @@ -0,0 +1,161 @@ +# Docker Compose configuration for E2E testing +# Usage: docker compose -f docker-compose.e2e.yml up -d +# +# This configuration runs only the services needed for E2E pricing tests: +# -
