[typespec-python] Add generated test regeneration workflow by iscai-msft · Pull Request #46414 · Azure/azure-sdk-for-python

iscai-msft · 2026-04-20T18:24:00Z

Summary

Add a GitHub Actions workflow that regenerates Python SDK test code from microsoft/typespec's http-client-python emitter and stores the output in eng/tools/typespec-python-generated-tests/.

Motivation

The TypeSpec Python emitter (@typespec/http-client-python) generates test code against http-specs and azure-http-specs test suites. Currently these generated tests aren't tracked anywhere persistent. This workflow keeps a canonical copy in azure-sdk-for-python, updated automatically when the emitter changes.

How it works

Triggers

repository_dispatch — automated, triggered from microsoft/typespec when http-client-python merges to main
workflow_dispatch — manual, with configurable typespec_ref (branch, tag, SHA, or main for latest unreleased code)

Steps

Checks out azure-sdk-for-python and microsoft/typespec (at specified ref)
Builds http-client-python from source (no npm publish required)
Runs npm run regenerate to generate both azure and unbranded flavors
Copies output to eng/tools/typespec-python-generated-tests/{azure,unbranded}/
Creates an auto-merge PR with the changes

Output structure

eng/tools/typespec-python-generated-tests/
├── azure/        # Generated from azure-http-specs
├── unbranded/    # Generated from http-specs
└── README.md

Add typespec-python-regen.yml workflow that regenerates Python SDK test code from microsoft/typespec's http-client-python emitter. Outputs both azure and unbranded flavors to eng/tools/typespec-python-generated-tests/. Triggers: - repository_dispatch (from microsoft/typespec on merge) - workflow_dispatch (manual, with configurable ref) Creates an auto-merge PR when regenerated code changes.

- Add dispatch sender validation guard - Use fetch-depth: 0 for reliable PR branch creation - Inline ref expression in checkout to avoid GITHUB_OUTPUT injection - Sanitize ref value before writing to GITHUB_OUTPUT for PR metadata - Make auto-merge conditional on workflow_dispatch only (not repository_dispatch) - Update README with full regeneration steps (install, build, prepare) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Rename folder: typespec-python-generated-tests -> tsp-python-gen (fixes path length >260 chars) - Rename workflow: typespec-python-regen.yml -> typespec-python-regenerate.yml (fixes cspell 'regen' errors) - Replace 'Regen' with 'Regenerate' in workflow name and dispatch type - Add CODEOWNERS for tsp-python-gen/ and the workflow file Owners: @tadelesh @msyyc @iscai-msft @lmazuel @lirenhe Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Use native gh CLI for PR creation instead of third-party action. Commits only eng/tools/tsp-python-gen/ changes, force-pushes to a fixed branch, and creates or updates an existing PR. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- Replace repository_dispatch with daily schedule (8:00 UTC) - Add check-version job that compares npm version to .last-version marker - Only regenerate when a new version is detected or manually triggered - Update .last-version marker after each regeneration - Remove dispatch sender validation (no longer applicable) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

- repository_dispatch: fired by typespec publish pipeline after npm release - schedule: daily 8:00 UTC fallback to catch any missed dispatches - workflow_dispatch: manual trigger with configurable ref - Checkout uses dispatch sha when available Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Approving the github workflow. Manually triggered. Doesn't use 3P actions. Pins 1P actions to versions.

Nit: please run this script against your action before merging -- just to double check.

Run this with -Path .github/workflows/typespec-python-regenerate.yml and make certain nothing changes.

The generated test files under emitter/ were being included in the azure-sdk-tools pip install, ending up in venv/lib/site-packages/ and triggering path length violations. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The previous location eng/tools/azure-sdk-tools/emitter/generated/ had two issues: 1. Files were included in azure-sdk-tools pip install (into venv site-packages) 2. Path prefix was too long (44 chars), causing 22 files to exceed the 260-char Windows path limit New location eng/emitter/gen/ (16 chars) saves 28 chars, eliminating all path length violations. Also reverts the pyproject.toml workaround since files are no longer under azure-sdk-tools. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
