How to mock an artifact store with local paths in Python for ML pipelines

Create a temporary local artifact store with dummy files and metadata to test ML pipeline code without real storage.

ml-pipelines mock tempfile
Python 
import tempfile
from pathlib import Path
import json


def create_artifact_store_mock(base_path: Path = None):
    """Create a local artifact store mock directory structure."""
    if base_path is None:
        base_path = Path(tempfile.mkdtemp())

Generate a Mock Artifact Version Tag in Python

Creates a mock build artifact version tag from a branch name and build number, with a date stamp.

artifact versioning ci
Python 
import re
from datetime import datetime

def mock_version_tag(branch_name: str, build_number: int) -> str:
    """Generate a mock build artifact version tag from branch and build number."""
    branch_slug = re.sub(r'[^a-zA-Z0-9]+', '-', branch_name).strip('-').lower()

How to Mock Multi-Stage Docker Builds in Python

Simulate a multi-stage Docker build in pure Python using classes and temp directories to understand how build stages copy artifacts into a final image.

docker multi-stage simulation
Python 
# Simulate multi-stage Docker build with pure Python
from pathlib import Path
import tempfile
import shutil

class BuildContext:
    """Mimics a Docker build context with stages."""
    
    def __init__(self, name):
        self.name = name
        self.files = {}
