# 🎉 TDD Remediation Implementation Summary
## 📊 Executive Summary
We have successfully implemented the **TDD approach** for the three highest priority remediation elements identified in our ADR adherence analysis. This represents a major milestone in transforming our already excellent implementation from "100% ADR compliant" to "exemplary production-ready."
## ✅ **COMPLETED IMPLEMENTATIONS**

**Status**: **FULLY IMPLEMENTED**
-**Configuration**: Created `.nextest/config.toml` with proper profiles
-**Profiles**: Default, CI, and Performance profiles configured
-**Testing**: Successfully tested with Button component (25 tests passed)
-**Benefits**: Prevents test hanging, improves execution speed, better parallelization
**Key Features**:
```toml
[profile.default]
test-threads = 4
retries = 2
slow-timeout = { period = "60s", terminate-after = 2 }
leak-timeout = "10s"
fail-fast = false
```
