# Ace E2E Test Suite Ready

This document certifies that the comprehensive, opaque-box, requirement-driven E2E test suite for Ace is fully functional and ready.

## Certification Statement

We certify that the Ace E2E test suite is complete and passing. It runs against the CLI application interface and Git repository states, utilizing a local mock LLM HTTP server to simulate language model responses. The test suite contains 71 test cases distributed across four tiers, covering happy paths, boundaries, pairwise combinations, and real-world workloads for all 6 core features of the system.

## Test Suite Execution

### Command
To execute the End-to-End test suite, run the following command from the project root:
```powershell
.venv\Scripts\pytest -v tests/e2e/ -p no:langsmith
```

### Summary of Results
- **Tier 1 (Feature Coverage)**: 30 / 30 Passed
- **Tier 2 (Boundaries & Edge Cases)**: 30 / 30 Passed
- **Tier 3 (Cross-Feature Combinations)**: 6 / 6 Passed
- **Tier 4 (Real-world Workloads)**: 5 / 5 Passed
- **Total Tests**: 71 Passed

## Feature Coverage Mapping

### 1. NL Planner (Natural Language mode)
- Happy paths: status, commits, branch switching, branch creation, multi-command execution.
- Boundaries: empty query, non-git directory execution, dry-runs, destructive warnings, and irrelevant inputs.
- Combinations: configuration verification, diagnostic integration.
- Workloads: hotfixes, feature branch lifecycles, and destructive restorations.

### 2. Commit Generator (`ace commit`)
- Happy paths: conventional, simple, detailed formatting, interactive skipping, and prepare-commit-msg hook template generation.
- Boundaries: execution with empty stage, empty diffs, invalid format falling back, missing credentials warning, and very long diff trimming.

### 3. Config Wizard / Display (`ace config` / `ace setup`)
- Happy paths: display current configuration settings table, interactive wizard configurations for NVIDIA, Ollama, OpenAI, and custom OpenAI-compatible providers.
- Boundaries: default selection fallback, invalid provider input recovery, non-existent configuration directory/file handling, and file system write failures.

### 4. Changelog Generator (`ace changelog`)
- Happy paths: terminal printing, file output, explicit commit ranges, offline Ollama enforcement, and empty history messaging.
- Boundaries: invalid ref logs error handling, single-commit range formatting, overwrite existing file behavior, and complex commit messages encoding.

### 5. PR Drafter (`ace pr`)
- Happy paths: description drafting terminal printing, file output, offline mode, and base branch override.
- Boundaries: invalid base branch name errors, empty diff check failures, and read-only destination directory handling.

### 6. Diagnostics & Recovery (`ace doctor` & `ace undo`)
- Happy paths: doctor health checks, untracked large file detections, undo commits, undo staged additions, and interactive undo aborts.
- Boundaries: lock file detections, detached HEAD checks, clean repository undos, and destructive undo confirmations.
