# Phase 22 Plan 02: Log Flags Tests Summary

**One-liner:** E2E test coverage for all 20 LOG requirements validating flag translation, output formats, and warning messages.

## What Was Built

Extended `tests/test_log.py` from 15 tests to 45 tests covering all log flag requirements:

### Display Flags Tests (LOG-01, LOG-02, LOG-03)
- `--graph` flag shows ASCII commit graph
- `--stat` flag shows diffstat with each commit
- `--patch/-p` flag shows diff content

### Filter Flags Tests (LOG-04, LOG-05)
- `--author=pattern` and `--author pattern` syntax
- `--grep=pattern` and `--grep pattern` syntax

### Behavior Flags Tests (LOG-06, LOG-07, LOG-08)
- `--no-merges` excludes merge commits
- `--all` shows all branches
- `--follow` follows file renames

### Date Flags Tests (LOG-09, LOG-10)
- `--since/--after` date filters
- `--until/--before` date filters
- Combined date range filtering

### Output Format Flags Tests (LOG-11, LOG-12, LOG-13, LOG-14)
- `--name-only` shows only filenames
- `--name-status` shows status+filename
- `--decorate` shows branch/bookmark names
- `--pretty/--format` with oneline/short/medium/full presets
- Custom format placeholders (%h, %s)

### Complex Flags Tests (LOG-15, LOG-16)
- `--first-parent` follows only first parent
- `--reverse` shows commits in reverse order

### Pickaxe Warning Tests (LOG-17, LOG-18)
- `-S` pickaxe warns about unsupported feature
- `-G` regex pickaxe warns about unsupported feature

### Existing Flags Tests (LOG-19, LOG-20)
- `--max-count/-n` limit already implemented
- `--oneline` already implemented

## Commits

| Hash | Description |
|------|-------------|
| 40221a9 | test(22-02): add E2E tests for display flags (LOG-01, LOG-02, LOG-03) |
| a82e4f2 | test(22-02): add E2E tests for filter flags (LOG-04 through LOG-10) |
| 10300ee | test(22-02): add E2E tests for output format flags (LOG-11 through LOG-14) |

## Deviations from Plan

None - plan executed exactly as written.

## Verification Results

All verification checks passed:
1. `pytest tests/test_log.py -v` - 45 tests passed
2. `pytest tests/test_log.py --tb=short` - no unexpected failures
3. Test count: 45 tests (requirement: 35+)
4. File size: 458 lines (requirement: 300+)

## Phase 22 Completion

Phase 22 (Log Flags) is now complete:
- Plan 22-01: Implementation of 18 new log flags
- Plan 22-02: E2E tests for all 20 LOG requirements

All success criteria met:
1. All 20 LOG requirements have at least one test
2. All new tests pass with the implementation from 22-01
3. Existing tests still pass (no regressions)
4. Tests cover both success cases and warning cases
5. Test output is clean (no unexpected warnings)
