TDD engine for Analytics Engineering — generate unit test data for SQL queries
Project description
MockSQL — Backend
FastAPI + LangGraph + CLI
Ce dossier contient le cœur de MockSQL : l'API REST, le graph LangGraph de génération de données, le CLI, et le package mocksql-ui (serveur web + assets React).
Quickstart local
Prérequis : Python ≥ 3.11, Poetry ≥ 1.8, un projet Google Cloud avec la facturation activée.
1. Authentification Google Cloud
gcloud auth application-default login
gcloud config set project <PROJECT_ID>
2. Variables d'environnement
cp .env.example .env # puis compléter les valeurs
Variables minimales requises :
PROJECT_ID=<votre-projet-gcp>
GOOGLE_CLOUD_PROJECT=<votre-projet-gcp>
BQ_SCHEMA_BILLING_PROJECT=<votre-projet-gcp>
DEFAULT_MODEL_NAME=gemini-2.0-flash-lite
DUCKDB_PATH=data/mocksql.duckdb
SECRET_KEY=<générer avec : python -c "import secrets; print(secrets.token_hex(32))">
API_SECRET_KEY=<idem>
FRONT_URL=http://127.0.0.1:3000
3. Installation & lancement
python -m venv .venv
# Linux / macOS
source .venv/bin/activate
# Windows
.\.venv\Scripts\activate
pip install poetry && poetry install
# Lancer le serveur
uvicorn server:app --port 8080 --reload
L'API est accessible sur http://localhost:8080, le frontend sur http://localhost:3000 (voir ../front/README.md).
Commandes de développement
make style # ruff check + ruff format --check + vulture (code mort)
make format # ruff format + ruff check --fix (auto-correction)
make test # pytest
make check # style + test
Type checking :
poetry run mypy build_query/ app/
Packaging
MockSQL produit deux wheels indépendants :
| Wheel | Contenu |
|---|---|
mocksql-*.whl |
CLI + LangGraph core (sans UI) |
mocksql_ui-*.whl |
Serveur web + assets React bundlés |
Builder les wheels
# CLI uniquement
make build-cli
# CLI + UI (build React inclus — Node.js 18+ requis)
make build-ui
Les wheels sont générés dans dist/.
Lancer l'UI depuis les wheels
pip install dist/mocksql-*.whl dist/mocksql_ui-*.whl
mocksql ui # http://localhost:8080/static/
mocksql ui --port 4000
mocksql ui --no-browser
Déploiement
Variables d'environnement (production)
Voir .env.example pour la liste complète. En production (Cloud Run), les secrets sont gérés via Google Secret Manager ou les variables d'environnement du service.
Conteneurisation (Docker)
docker build -t mocksql-backend .
docker run -d -p 8080:8080 \
-e PROJECT_ID=<votre-projet-gcp> \
-e GOOGLE_APPLICATION_CREDENTIALS=/keys/sa.json \
-v ~/keys:/keys \
mocksql-backend
Google Cloud Run
1. Build & push
gcloud builds submit --tag gcr.io/${PROJECT_ID}/mocksql-backend .
2. Secrets
gcloud secrets create mocksql-env --data-file .env
3. Déploiement
gcloud run deploy mocksql-backend \
--image gcr.io/${PROJECT_ID}/mocksql-backend \
--region europe-west1 \
--platform managed \
--allow-unauthenticated \
--memory 1Gi \
--service-account mocksql-sa@${PROJECT_ID}.iam.gserviceaccount.com
Infrastructure Terraform
cd ../terraform
cp variables.example.tfvars my_variables.tfvars
# compléter project_id, region, etc.
terraform init
terraform apply --var-file=my_variables.tfvars
Rôles requis pour le compte de service Terraform :
- Cloud SQL Admin
- Project IAM Admin
- Service Account Admin
- Service Usage Admin
- BigQuery Admin
