Data-Driven & Cross-Browser Testing — quiz

You're reading test data from a `.xlsx` file using Apache POI. Which class do you use, and what's the typical read pattern?

• `HSSFWorkbook` — works for both `.xls` and `.xlsx`
• `XSSFWorkbook` — open with `new XSSFWorkbook(new FileInputStream(path))`, get the sheet, iterate `Row` objects, read each `Cell` with the appropriate `getStringCellValue()` / `getNumericCellValue()` based on `getCellType()`
• `Workbook.open(file)` — POI auto-detects
• POI doesn't support `.xlsx` — use a different library
