# Verification and Validation Report
## Document Control
| Field | Value |
|-------|-------|
| Document ID | VV-DOT-001 |
| Version | 0.2.501 |
| Date | 2026-03-20 |
| Author | Repository Maintainer |
| Status | Active |
| Classification | Internal |
| Standard | ISO 13485:2016 Sections 7.3.6 / 7.3.7 (adapted) |
## Purpose
This document constitutes the formal Verification and Validation (V&V) report for the chezmoi-managed dotfiles repository, adapted from ISO 13485:2016 Sections 7.3.6 (Design and Development Verification) and 7.3.7 (Design and Development Validation) for infrastructure-as-code.
**Verification** confirms that each design output meets its corresponding design input requirement through inspection, analysis, and testing. **Validation** confirms that the deployed system satisfies its intended use under representative operating conditions (Linux, macOS, WSL).
All verification activities are executed through automated CI pipelines, pre-commit hooks, and the repository test framework. Evidence is retained in CI logs, test output, and this document.

## Test Framework Architecture
### Directory Structure
```
tests/
├── framework/
│ ├── test_runner.sh # Test executor — discovers and runs all test_*.sh files
│ ├── assertions.sh # 16 assertion functions (assert_equals, assert_contains, etc.)
│ └── mocks.sh # Mock utilities for isolating external dependencies
├── unit/
│ ├── aliases/ # Alias and command-surface tests
│ ├── functions/ # Function behavior tests
│ ├── dot-cli/ # `dot` command workflow tests
│ ├── shell/ # Shell integration and completion tests
│ ├── fish/ # Fish function and completion tests
│ ├── nushell/ # Nushell configuration tests
│ ├── nvim/ # Neovim configuration tests
│ └── test_*.sh # 425 unit test files total
├── integration/
│ └── test_*.sh # 11 integration test files
└── performance/
└── benchmark_runner.sh # Performance regression benchmarks
```
### Execution Model
1. `test_runner.sh` recursively discovers all `test_*.sh` files under `tests/`.
2. Each test file is executed in a subshell with `assertions.sh` sourced.
3. Tests source bash files directly from the repository (not Go templates).
4. `mocks.sh` provides stubs for external tools (`chezmoi`, `git`, `brew`, etc.).
5. Exit codes and assertion counts are aggregated into a final report.
### Assertion Library
| Function | Purpose |
|----------|---------|
| `assert_equals` | Exact string equality |
| `assert_not_equals` | String inequality |
| `assert_contains` | Substring match |
| `assert_not_contains` | Substring absence |
| `assert_starts_with` | Prefix match |
| `assert_ends_with` | Suffix match |
| `assert_matches` | Regex match |
| `assert_file_exists` | File presence |
| `assert_file_not_exists` | File absence |
| `assert_directory_exists` | Directory presence |
| `assert_command_exists` | Command availability |
| `assert_exit_code` | Process exit code |
| `assert_empty` | Empty string |
| `assert_not_empty` | Non-empty string |
| `assert_true` | Boolean truth |
| `assert_false` | Boolean false |
