Introduction

Building a Reusable Testing Framework

Objective

Run the testing framework simulator with 12 configured layers. Observe the YAML configuration, layer execution with trigger filtering, markdown dashboard with summary, layer results table, failures, and recommendations. Try different triggers (commit, pr, nightly) to see which layers run.

One command: verify. Wraps pytest + Hypothesis + mutmut + Semgrep + Z3 into a unified framework.
