Creating a New Java E2E Test with a Replay Proxy YAML Snapshot

Repository layout

These instructions work in both the runtime monorepo and the standalone public SDK repository. From the repository root, use src/sdk as the SDK root when that directory exists; otherwise use the repository root itself. All paths below are relative to that SDK root.

Use this skill only when the new E2E tests Java SDK surface area; shared runtime functionality available entirely through the SDK belongs in the TypeScript SDK suite (nodejs/test/e2e/).

Overview

The Java E2E tests use a replay proxy (test/harness/replayingCapiProxy.ts) that intercepts HTTP calls to the Copilot API and returns pre-recorded responses from YAML snapshot files. This avoids needing real authentication in CI.
