# Phase 2: E2E Test Infrastructure Verification Report

**Phase Goal:** Test harness can compare git and gitsl behavior on temp repositories
**Verified:** 2026-01-18T00:45:00Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Test can create temp git repo with `tempfile.mkdtemp()` and clean up after | VERIFIED | `git_repo` fixture in conftest.py uses pytest's `tmp_path` (built on tempfile), creates repo with `git init`, auto-cleanup by pytest |
| 2 | Test can run `git <cmd>` and capture stdout, stderr, exit code | VERIFIED | `run_git()` in conftest.py calls `run_command()` which uses `subprocess.run(capture_output=True)`, returns `CommandResult` with all 3 fields |
| 3 | Test can run `gitsl <cmd>` and capture stdout, stderr, exit code | VERIFIED | `run_gitsl()` in conftest.py locates `gitsl.py` and runs via subprocess, returns `CommandResult` |
| 4 | Test can assert exit codes match between git and gitsl | VERIFIED | `assert_commands_equal()` in comparison.py compares exit codes with assertion error on mismatch |
| 5 | Test can assert exact output match (for porcelain formats) | VERIFIED | `compare_exact()` in comparison.py performs `expected == actual` string comparison |
| 6 | Test can assert semantic output match (ignoring whitespace, timestamps for human formats) | VERIFIED | `compare_semantic()` normalizes whitespace and empty lines before comparison |
| 7 | Test fixtures can create repos with: initial commit, modified files, untracked files, branches | VERIFIED | Four fixtures: `git_repo`, `git_repo_with_commit`, `git_repo_with_changes`, `git_repo_with_branch` |

**Score:** 7/7 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `tests/__init__.py` | Package marker | EXISTS (0 lines) | Package marker, expected to be empty |
| `tests/helpers/__init__.py` | Subpackage marker | EXISTS (0 lines) | Subpackage marker, expected to be empty |
| `tests/helpers/commands.py` | CommandResult dataclass, run_command helper | SUBSTANTIVE (59 lines) | Exports: CommandResult, run_command. Has success property. |
| `tests/helpers/comparison.py` | Output comparison utilities | SUBSTANTIVE (129 lines) | Exports: compare_exact, compare_semantic, assert_output_match, assert_commands_equal, generate_diff |
| `tests/conftest.py` | Shared pytest fixtures and command runners | SUBSTANTIVE (131 lines) | Exports: run_git, run_gitsl, git_repo, git_repo_with_commit, git_repo_with_changes, git_repo_with_branch |
| `tests/test_harness.py` | Self-validation tests for harness | SUBSTANTIVE (297 lines, 35 tests) | 10 test classes validating all harness components |
| `pytest.ini` | Pytest configuration | EXISTS (3 lines) | Configures pythonpath and testpaths for tests/ module |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| tests/conftest.py | tests/helpers/commands.py | `from helpers.commands import CommandResult, run_command` | WIRED | Line 10 - imports both exports |
| tests/conftest.py | gitsl.py | `gitsl_path = Path(__file__).parent.parent / "gitsl.py"` | WIRED | Line 48 - run_gitsl locates and executes gitsl.py |
| tests/test_harness.py | tests/conftest.py | pytest fixture injection | WIRED | 15 test functions use fixtures (git_repo, git_repo_with_commit, etc.) |
| tests/test_harness.py | tests/helpers/comparison.py | `from helpers.comparison import ...` | WIRED | Line 14-18 - imports compare_exact, compare_semantic, assert_commands_equal |
| tests/test_harness.py | tests/helpers/commands.py | `from helpers.commands import CommandResult` | WIRED | Line 13 - imports CommandResult for test assertions |

### Requirements Coverage

Based on ROADMAP.md, Phase 2 covers: TEST-01, TEST-02, TEST-03, TEST-04, TEST-05, TEST-06, TEST-07

| Requirement | Status | Notes |
|-------------|--------|-------|
| TEST-01 (temp repo creation) | SATISFIED | git_repo fixture |
| TEST-02 (git output capture) | SATISFIED | run_git + CommandResult |
| TEST-03 (gitsl output capture) | SATISFIED | run_gitsl + CommandResult |
| TEST-04 (exit code comparison) | SATISFIED | assert_commands_equal |
| TEST-05 (exact match) | SATISFIED | compare_exact |
| TEST-06 (semantic match) | SATISFIED | compare_semantic |
| TEST-07 (fixture variety) | SATISFIED | 4 fixture types |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| - | - | - | - | No anti-patterns found |

Scanned all 6 Python files in tests/ for TODO, FIXME, placeholder, not implemented patterns. No matches found.

### Human Verification Required

None required. All capabilities are programmatically verified via the 35 passing tests in test_harness.py.
