Test all the things!

The alternative to testing the whole path is discovering failures by breaking the whole app. This hackathon project makes the same core scenarios runnable locally, in CI, and in production.

The goal is not one giant test. It is one reusable flow at three confidence levels: fast local feedback, deterministic CI coverage, and continuous confirmation against production.

The check is versioned in Git and gcx deploys it only when it changes. History is the first browser-based proof of concept because it is valuable and easy to forget. The same setup can run locally, while Doppler supplies environment-specific configuration.

The improved local runtime gives us a real application, transport, worker, and session path. Expensive or unstable dependencies can be swapped between mocks and real services. The Cube mock server is useful now and can also protect the migration away from Cube later.

The Playwright scaffold lets us choose the integration depth for the purpose: full local exploration, fast PR feedback, pre-merge incident prevention, and scheduled production verification can all share the same UI flow.

Both Kubernetes clusters already have Argo Rollouts through the central cf-argocd. Cloudflare Deploy v2 can perform a gradual rollout when a service supplies smoke-tests/run.ts. The open problem is probe coverage: Synthetic Monitoring depends on other deployed services, and Bruno covers only around forty percent of applications. Scope whether the remaining work fits into one sprint.

Close with the work that remains. Each stream needs a small amount of hardening or design before it becomes routine. Convert these next steps into backlog tasks after the hackathon.
