# #158 3 AL/BC patterns from CURABIS's internal automated-testing training material

> Four new AL/BC best practice patterns were added covering item ledger entry document numbers after combined posting and three testing approaches for verifying field UI state and generating unique test values.

[Pull request](https://github.com/microsoft/BCQuality/pull/158) · merged into `main` on 2026-09-29 by MichaelDieringer · 14 files (+255 -3), 14 AL · feature · tier official · reviewed (checked by Opus)

## What changed

- Item Ledger Entry carries the shipment's document number, not the invoice number, after combined Ship and Invoice posting of sales orders
- Use TestPage field .Visible()/.Enabled() to verify UI rendering state and .Editable() via OpenEdit() for editability verification
- Generate test fixture values with GenerateGUID() for full-length fields or GenerateRandomCodeWithLength/GenerateRandomCode20 when uniqueness must be verified
- Four atomic AL-specific patterns documented with good/bad code examples from CURABIS internal training material
- Patterns cover data modeling and testing domains with best practices and anti-patterns
