Goal

Generate executable *PostMigrationIT tests from the frozen baseline specification and run them against the migrated application.

The baseline phase produces no test code — it produces a precise specification, including the test-cases, infra-decision-table, and testdata. This skill is the sole place where integration test code is generated.

When the baseline decision table includes testcontainer rows, verification MUST run those dependencies against containerized emulators/services (not cloud resources and not mocks).

User Input

• taskid — Identifier for this verification run.
• modernization-work-folder — Folder under which the verification summary and decision table are written.

Terminology

Event-sourced subscriber — any entry point invoked by an external event source rather than by a synchronous caller: message-queue listeners, event-bus / event-hub / event-grid handlers, storage-event triggers (e.g. blob-created or object-deleted handlers), DB change-feed / CDC handlers, inbound-email handlers, file-system watchers. Throughout this document, "event-sourced subscriber" refers to this entire family; the only legitimate trigger for such an entry point is a real event produced on the declared source via its SDK or wire protocol.

Testcontainer dependency — an external dependency marked testcontainer in infra-decision-table.md; verification must instantiate and use a containerized emulator/service for that dependency via the project's Testcontainers stack.
