Alibaba Cloud Performance Testing Service (PTS)

Purpose

Use Alibaba Cloud PTS OpenAPI to support:

• test scene inventory and inspection
• pressure test planning and lifecycle automation
• report and metrics retrieval for verification and troubleshooting

Prerequisites

• Configure least-privilege Alibaba Cloud credentials.
• Install Python SDKs (virtual environment recommended):

python3 -m venv .venv
. .venv/bin/activate
python -m pip install -U alibabacloud_pts20201020 alibabacloud_tea_openapi

• Prefer environment variables:

- ALICLOUD_ACCESS_KEY_ID - ALICLOUD_ACCESS_KEY_SECRET - optional ALICLOUD_REGION_ID

• Before mutating operations, run read-only API discovery and current-state checks.

AccessKey Priority

1. Environment variables: ALICLOUD_ACCESS_KEY_ID / ALICLOUD_ACCESS_KEY_SECRET / ALICLOUD_REGION_ID
2. Shared credentials file: ~/.alibabacloud/credentials

If region/environment is unclear, confirm with user before mutating operations.

Workflow

1. Identify target region, test scene identifiers, and operation scope.
2. Run API discovery to confirm API names and required parameters.
3. Execute read-only APIs first (List* / Get* / Describe*).
4. Execute mutating operations only after confirming rollback and change window.
5. Save outputs and evidence to output/alicloud-observability-pts/.

API Discovery

• Product code: PTS
• Default API version: 2020-10-20
• Metadata source: https://api.aliyun.com/meta/v1/products/PTS/versions/2020-10-20/api-docs.json

Minimal Executable Quickstart

python skills/observability/pts/alicloud-observability-pts/scripts/list_openapi_meta_apis.py

Optional arguments:

python skills/observability/pts/alicloud-observability-pts/scripts/list_openapi_meta_apis.py \
  --product-code PTS \
  --version 2020-10-20 \
  --output-dir output/alicloud-observability-pts

List scenes (read-only):

python skills/observability/pts/alicloud-observability-pts/scripts/list_pts_scenes.py \
  --region cn-hangzhou \
  --page-number 1 \
  --page-size 10 \
  --output output/alicloud-observability-pts/scenes.txt

Start one scene (mutating):

python skills/observability/pts/alicloud-observability-pts/scripts/start_pts_scene.py \
  --region cn-hangzhou \
  --scene-id <scene-id> \
  --wait \
  --output output/alicloud-observability-pts/start-result.json

Stop one scene (mutating):

python skills/observability/pts/alicloud-observability-pts/scripts/stop_pts_scene.py \
  --region cn-hangzhou \
  --scene-id <scene-id> \
  --wait \
  --output output/alicloud-observability-pts/stop-result.json

Common Operation Map

• Scene inventory: ListPtsScene, GetPtsScene, ListOpenJMeterScenes, GetOpenJMeterScene
• Scene lifecycle: CreatePtsScene, SavePtsScene, ModifyPtsScene, DeletePtsScene, DeletePtsScenes
• Test execution control: StartPtsScene, StopPtsScene, StartTestingJMeterScene, StopTestingJMeterScene
• Debug control: StartDebugPtsScene, StopDebugPtsScene, StartDebuggingJMeterScene, StopDebuggingJMeterScene
• Reports/metrics: ListPtsReports, GetPtsReportDetails, GetPtsSceneRunningData, GetPtsSceneRunningStatus

See references/api_quick_map.md for grouped API lists.

Script Catalog

• scripts/list_openapi_meta_apis.py: fetch metadata and generate API inventory files.
• scripts/list_pts_scenes.py: list PTS scenes with pagination.
• scripts/start_pts_scene.py: start a scene and optionally poll running status.
• scripts/stop_pts_scene.py: stop a scene and optionally poll until non-running.

Output Policy

Write generated files and execution evidence to: output/alicloud-observability-pts/

Validation

mkdir -p output/alicloud-observability-pts
for f in skills/observability/pts/alicloud-observability-pts/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/alicloud-observability-pts/validate.txt

Pass criteria: command exits 0 and output/alicloud-observability-pts/validate.txt is generated.

Output And Evidence

• Save artifacts, command outputs, and API response summaries under output/alicloud-observability-pts/.
• Include key parameters (region/resource id/time range) in evidence files for reproducibility.
