## Test Data Examples

### Valid Issue
```python
{
    "key": "PROJ-1",
    "id": "123",
    "fields": {
        "summary": "Issue Title",
        "description": "Description",
        "status": {"name": "In Progress"},
        "issuetype": {"name": "Story"},
        "issuelinks": [...]
    }
}
```

### Valid Link
```python
{
    "type": {"name": "relates to"},
    "outwardIssue": {"key": "PROJ-2"}
}
```

### Valid Project Export
```python
{
    "issues": [
        {"key": "PROJ-1", "id": "123", "fields": {...}},
        {"key": "PROJ-2", "id": "124", "fields": {...}}
    ]
}
```

## Error Scenarios Tested

1. Invalid JSON format
2. Missing required fields
3. Type mismatches
4. Unknown status/type/link values
5. Missing target issues in links
6. Project creation failures
7. Item creation failures
8. Link creation failures
9. None/null values in nested fields
10. Empty collections

## Performance Notes

2. Integration tests with real database
3. Concurrent import tests
4. API response validation tests
5. Custom field mapping tests
6. Bulk operation tests
7. Memory usage tests
