- release-must-update-app-version.md: reframe around AppSource's actual
strict full-version-ordering requirement; scope branching-policy
claims as team convention, not platform rule.
- pictures-must-use-media-not-blob.md: MediaSet is a collection of
independent media objects, not automatic image variants/thumbnails.
- log-writes-must-survive-rollback.{md,good.al}: StartSession's only
data channel into the new session is its Record parameter to a
TableNo-scoped codeunit; a setter called on a local instance before
starting the session populates nothing in the new session.
- exposed-objects-must-be-in-a-permission-set.md: correct the three
exposure mechanisms (Web Services config, PageType/QueryType=API,
ServiceEnabled as a method-only attribute).
- pages-must-not-contain-business-logic.md: scope to persisted
mutations and cross-entry-point rules; presentation-only
calculations and table-owned invariants are not violations.
- given-blocks-must-cover-full-precondition-chain.good.al: replace
invented LibrarySales calls with the real API
(CreateCustomer/CreateSalesOrderForCustomerNo/PostSalesDocument).
- test-feature-scenario-tags.{md,good.al}: move [SCENARIO] inside the
test procedure body to match the current BCApps corpus; keep
[FEATURE] at codeunit level per Microsoft's own documented option.
- ui-test-codeunit-naming.md: scope the _UT suffix and adjacent-ID
pairing as an explicit team convention, not a BCApps-wide standard.
- page-design-must-match-bc-page-type-conventions.md /
table-design-must-match-bc-table-type-conventions.md: Card's
single-key primary-key claim is a contextual heuristic, not a
mandatory constraint (Ship-to Address, Customer/Vendor Bank Account
are real composite-key Card pages); a Subsidiary table with its own
identity commonly gets List+Card, not Worksheet/Tabular.
- api-page-least-privilege-write-access.{md,good.al}: only page-placed
fields are ever exposed; set InsertAllowed/DeleteAllowed=false in the
good sample so a narrow field set can't still create/delete records.
- source-organized-by-feature-not-object-type.md,
test-one-when-per-test.md: scope as team/testing-design conventions,
not Microsoft platform requirements.
- upgrade-tag-logic-must-not-nest-deeply.md: add the Microsoft Learn
citation that already backs the two-level nesting limit.
- Wire the new articles into the testing/data-modeling/error-handling/
security/ui review skills' candidate-selection signals.

Separate UI-layer and logic-layer tests into different codeunits
Description
A test codeunit that drives pages through TestPage — opening pages, reading FactBox parts, triggering field OnValidate through the page — is testing a different layer than a codeunit that calls business-logic procedures directly. Readers need to know which layer a given test exercises without opening it, and a single codeunit that mixes both kinds of test hides that distinction: a failure could mean the logic broke, the page broke, or both. The _UT suffix and adjacent-object-ID pairing below are one team's naming convention for making that split visible, not a BCApps-wide naming standard — BCApps itself uses UT for unit tests generally, not specifically to mean "UI layer," and does not treat adjacent object IDs as a semantic pairing mechanism. Apply the suffix only on a project that has explicitly adopted this convention.
Best Practice
Keep UI-layer (TestPage-driven) and logic-layer tests in separate codeunits regardless of naming. Projects that adopt a _UT-style suffix convention should apply it consistently to every UI-layer test codeunit, keep the corresponding logic-only codeunit unsuffixed, and document the convention where the team's other naming rules live.
See sample: ui-test-codeunit-naming.good.al.
Anti Pattern
One codeunit that mixes a direct logic-call test and a TestPage-driven test side by side — a failing test no longer tells a reader which layer actually broke. On a project that has adopted the _UT convention, a UI-layer codeunit missing the suffix is also an instance of this anti-pattern; on a project that has not adopted it, the suffix itself is not required.
See sample: ui-test-codeunit-naming.bad.al.
