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

[Michael Dieringer (MichaelDieringer)]

Summary

Third batch from CURABIS ApS, mined from CURABIS's own internal Academy course book on automated/BDD testing in Business Central. Same format as #156/#157 (6-key frontmatter, Description/Best Practice/Anti Pattern, sibling .good.al/.bad.al samples, no fenced code in the .md).

• data-modeling (1): after posting a sales order with Ship and Invoice together, the resulting Item Ledger Entry carries the shipment's document number (Sales Header."Last Shipping No."), not the posted invoice number — a lookup filtered on the invoice number silently matches zero rows.
• testing (2): verify a field's actual rendered UI state with TestPage field .Visible()/.Enabled() rather than an indirect check or no check at all; generate collision-free test fixture values with LibraryUtility.GenerateGUID() + CopyStr/MaxStrLen instead of hardcoded literals.

Most of the source book turned out to be BDD philosophy and CURABIS process content that doesn't clear BCQuality's admission test — these 3 are the genuinely atomic, non-obvious AL-specific patterns that survived a full read-through, checked against the current microsoft/knowledge/ corpus and CURABIS's own two prior PRs for overlap.

Test plan

• CI frontmatter/format validation passes
• Domain-owning reviewers confirm placement and accuracy per file
