Guidance: End to End testing

Show a customer the best way to setup functional testing of a integration scenario which leverages multiple different azure services. Want to show how to deploy the solution via a pipeline, run some functional tests from the pipeline, and based on the results, make a deploy don't deploy decision.

No files or tests are named. Start by reviewing the repository’s Bicep deployment structure and any existing Azure pipeline configuration, then define the representative multi-service scenario, functional-test stage, and deploy/no-deploy decision that the customer guidance should cover. Done means the complete workflow is documented and reproducible.
