Test in Production: From End-to-End Checks to Observability

We've got unit tests, functional tests, and integration tests — but where are our tests for production? How we define (and check for!) "correct behavior" for an app running in the wild?

In this workshop, we'll start by creating an end-to-end check together (like an integration test on prod!) on a fun, interactive demo app. Then, we'll go one level deeper by adding custom instrumentation.

You'll leave with a deeper understanding of how to ask questions of your app and how to think about ensuring "correctness" in production.

Prerequisites:
Folks should come prepared to make HTTP requests and parse JSON responses (in whatever language/environment they prefer).
