From ea869d28d4846e43ada098caa3deb8f36ae299f9 Mon Sep 17 00:00:00 2001 From: Lucas Jia Date: Mon, 8 Jun 2026 00:29:40 -0700 Subject: [PATCH 01/12] test(serve): harden model customization deployment integ tests Add post-deploy invoke verification and make the Bedrock import-job lifecycle robust in test_model_customization_deployment.py. - Verify deployed endpoints by invoking them and validating the response structure (LORA uses the adapter IC name, otherwise the default base IC). - Replace unconditional stop-all cleanup with age-based (>24h) and status-aware cleanup: stop only InProgress/Pending jobs and delete completed imported models, with logging on failures. - Add a class-scoped autouse cleanup_import_jobs fixture to replace the zzz-prefixed ordering hack. - Bound the import-job wait loop with a 60-minute timeout and fail fast on Failed status; fix importedModelName -> importedModelArn. - Delete the imported model after tests via a yielding deployed_model_arn fixture. - Configure bedrock-runtime with standard retries (10 attempts) and add a slow-marked, retrying test_bedrock_model_invoke to tolerate "model not ready" exceptions.

The Bedrock deployment suite is kept commented out for now; the Nova for Bedrock integ tests will be added in a follow-up.

Role is resolved via get_execution_role(). - Marked us_east_1 (Nova test account, us-east-1) to run in the PR check integ-tests-us-east-1 job; not gpu_intensive. - Replace the previously commented-out OSS-style Bedrock suite (it used the import-job API, which does not apply to Nova) and update the module docstring to describe both SageMaker and Bedrock deployment targets.
