Pipeline Configuration Test Coverage Summary

Overview

This document summarizes the comprehensive test suite created for the pipeline configuration system, covering all implemented features and ensuring robust testing of the completed buildout.

Test Structure

The test suite follows the existing project patterns for test mode management:

  • Unit Tests: Use ExUnit.Case with forced mock mode for fast, deterministic testing
