## 1. Objectives

|
5
|
The Media Importer project aims to provide a robust, efficient solution for organizing media files by date with proper timezone handling and conflict - **Naming Convention**: `{s/f}_{YYYYMMDD_HHMMSS}_{TestName}.md` format where:
|
|
|
6
|
- `s` = success, `f` = failure
|
|
|
7
|
- Followed by timestamp and test name (spaces converted to underscores)esolution.
|
|
|
8
|
|
|
|
9
|
Key objectives:
|
|
|
10
|
- Reliable EXIF/metadata extraction and date parsing
|
|
|
11
|
- Proper UTC time conversion for QuickTime/Apple media files
|
|
|
12
|
- Flexible organization patterns (year/month/day/hour)
|
|
|
13
|
- Safe file operations with dry-run capabilities
|
|
|
14
|
- Cross-platform compatibility (macOS/Linux)
|
|

### Development Workflow
|
|
|
19
|
|
|
|
20
|
When making changes to the project, follow this structured approach:
|
|
|
21
|
|
|
|
22
|
### Changelog Entries Format
|
|
|
23
|
|
|
|
24
|
All changelog entries should follow this format:
|
|
|
25
|
|
|
|
26
|
```
|
|
|
27
|
- Date time
|
|
|
28
|
- Bug/Feature description
|
|
|

|
- Changes made
|
|
|

|
```
|
|
|
31
|
|
|
|

|
```
|
|
|
34
|
- 2025-09-07 10:30
|
|
|
35
|
- Fixed data loss issue when processing already-sorted folders
|
|
|
36
|
- Added exclusion patterns for sorted/organized/processed folders
|
|
|
37
|
- Added --include-sorted flag to override exclusions when needed
|
|
|
38
|
```
|
|
|
39
|
|
|
|
40
|
### File Move Confirmation
|
|
|
41
|
|
|
|
42
|
Every file move operation should be confirmed:
|
|
|
43
|
- After moving a file, the script must check that the file exists at the destination.
|
|
|
44
|
- If the file is not present at the destination after the move operation, the script should immediately stop and report an error.
|
|
|
45
|
- This ensures data integrity and prevents silent data loss.
|
|
|
46
|
|
|
|
47
|
### Destination Inside Source Handling
|
|
|
48
|
|
|
|
49
|
- Given the script's purpose, the destination folder may be inside the source folder.
|
|
|
50
|
- In this case, all files within the destination folder must be excluded from scanning and processing.
|
|
|
51
|
- For extra safety: before processing any file, if its path matches (or is inside) the destination path, the script must report an error and stop immediately.
|
|
|
52
|
- This prevents accidental re-processing or moving of files that have already been sorted, ensuring data integrity.
|
|
|
53
|
|
|
|
54
|
### Testing
|
|
|
55
|
|
|
|
56
|
Testing is essential to ensure the script's reliability and data safety. The following methodology should be used:
|
|
|
57
|
|
|
|
58
|
#### Test Environment Setup
|
|
|
59
|
- The `samples` directory contains a variety of media files for testing.
|
|
|
60
|
- Create a dedicated working directory named `test` for each test run.
|
|
|
61
|
- Copy selected files from `samples` into the `test` directory to simulate real-world scenarios.
|
|
|
62
|
- Perform import operations using the script, targeting the `test` directory as the source and a subdirectory (e.g., `test/sorted`) as the destination.
|
|
|
63
|
|
|
|
64
|
#### Test Execution and Documentation
|
|
|
65
|
- Before and after each import operation, run `find` on both the source and destination directories to capture the file structure:
|
|
|
66
|
- Example: `find ./test > test/source_before.txt`
|
|
|
67
|
- Example: `find ./test/sorted > test/dest_before.txt`
|
|
|
68
|
- Log all results, including script output and directory listings, into a dedicated log file for each test.
|
|
|
69
|
|
|
|
70
|
#### Test Report Format
|
|
|
71
|
Each test must generate a comprehensive Markdown report in `test/test_report.md` with the following structure:
|
|
|
72
|
|
|
|
73
|
```markdown
|
|
|
74
|

```
|
|
|
162
|
|
|
|
163
|
#### Automated Test Runner
|
|
|
164
|
A comprehensive test runner script (`test_runner.sh`) is available to automate the testing process:
|
|
|
165
|
|
|
|
166
|
```bash
|
|
|
167
|
./test_runner.sh
|
|
|
168
|
```
|
|
|
169
|
|
|
|
170
|
The script provides:
|
|
|
171
|
- **Pre-configured test scenarios** for common use cases
|
|
|
172
|
- **Automatic report generation** in Markdown format
|
|
|
173
|
- **State capture** before and after test execution
|
|
|
174
|
- **Protection verification** with checkboxes
|
|
|
175
|
- **Custom test support** for specific scenarios
|
|
|
176
|
|
|
|
177
|
#### Test Categories
|
|
|
178
|
The test runner provides the following pre-configured test scenarios:
|
|
|
179
|
|
|
|
180
|
1. **Basic Functionality Test**: Tests processing of files with valid EXIF data to verify correct sorting and organization
|
|
|
181
|
2. **Unimportable Files Test**: Tests handling of files without EXIF data in both root and subfolders, without --collect-unimportable flag
|
|
|
182
|
3. **Mixed Content Test**: Tests processing of sortable and unimportable files in separate folders to verify cleanup behavior
|
|
|
183
|
4. **Safety Protections Test**: Tests destination exclusion and move confirmation mechanisms to prevent data loss
|
|
|
184
|
5. **UTC Conversion Test**: Tests UTC timestamp conversion for QuickTime/Apple EXIF data
|
|
|
185
|
6. **Subdirectory Processing Test**: Tests processing of files in nested subdirectories to ensure recursive file discovery
|
|
|
186
|
7. **Custom Test**: Allows user-defined test scenarios with custom file sets and commands
|
|
|
187
|
|
|
|
188
|
#### Test Result Persistence
|
|
|
189
|
The test runner includes automatic result persistence:
|
|
|
190
|
|
|
|
191
|
- **Archival Location**: Test results are saved as individual Markdown files in `test_reports/` directory
|
|
|
192
|
- **Naming Convention**: `{TestName}_{YYYYMMDD_HHMMSS}.md` format for easy identification
|
|
|
193
|
- **Contents Preserved**: Single self-contained Markdown file with:
|
|
|
194
|
- Complete test information and directory structures
|
|
|
195
|
- Full script execution output embedded inline (ANSI codes stripped for readability)
|
|
|
196
|
- Import log content included directly in the report
|
|
|
197
|
- **Excluded Files**: No separate files - everything is consolidated in the Markdown report
|
|
|
198
|
- **Historical Tracking**: Maintains complete test history for debugging and regression testing
|
|
|
199
|
|
|
|
200
|
#### Cleanup
|
|
|
201
|
- Review the test report and verify all aspects are documented
|
|
|
202
|
- Clean up the `test` directory after each test run to ensure a fresh environment for subsequent tests
|
|
|
203
|
- Archive important test reports in a `test_reports/` directory for future reference
|
|
|
204
|
|
|
|
205
|

|
|
210
|
- Updated Test 3 (Mixed Content Test) to use separate folders for sortable vs unimportable files

|
|
|
212
|
- Updated menu descriptions to reflect the changes
|
|
|
213
|

|
### 2025-09-07 21:30 - Git Ignore Enhancement
|
|
|
227
|
- Added test_reports/ to .gitignore to exclude generated test reports from version control
|
|
|
228
|
- Test reports are generated files that don't need to be tracked in Git
|
|
|
229
|
- Prevents large numbers of timestamped report files from cluttering the repository
|
|
|
230
|

|
|
235
|
- Added Test 8: Source Only Test to test runner
|
|
|

### 2025-09-07 20:45 - Test 7 Refinement
|
|
|
243
|
- Updated Test 7 to test --keep-empty-dirs functionality instead of cleanup
|
|
|
244
|
- Since cleanup is now default behavior, Test 7 now verifies empty directory preservation
|
|
|
245
|
- Renamed from "Cleanup Empty Directories Test" to "Keep Empty Directories Test"
|
|
|
246
|
- Updated test scenario to validate --keep-empty-dirs flag behavior
|
|
|
247
|
- Added command line option "keep-empty-dirs" for test 7
