Test Evidence: Attendance feature package and JPA boundaries

Test type: Unit
Requirement IDs: ARC-005, OPS-020
Scenario IDs: I1-ATT-01 through I1-ATT-05 structural gate
Test class/method: com.lab.labtimesheet.architecture.AttendanceLayerStructureTest
Implementation commit: 8b48e281f7e860af435ae35b16c4edeb139286dc

Protected behavior

Attendance/calendar code lives under one feature.attendance boundary with controller, model, model.dto, model.entity, repository, service, and exception layers. The superseded feature-first and global-layer classes are absent, and application services do not depend on JdbcTemplate. Attendance does not map or expose the account feature's app_users or intern_profiles tables.

Test method

Plain JUnit loads the required public classes by authoritative package name, proves superseded class names are absent, verifies the query repository is a Spring Data repository, reflects over application-service dependencies, and proves that attendance-owned account entities/repositories cannot be loaded.

Hand-derived expected result

Seven representative classes load from feature.attendance internal layers; the old attendance.AttendanceService and global controller.AttendanceController do not load; query access implements Spring Data Repository; no checked application service has a JdbcTemplate field. The four forbidden attendance-owned account entity/repository class names do not load.

RED

Command

export JAVA_HOME=/opt/homebrew/opt/openjdk@25
export PATH="$JAVA_HOME/bin:$PATH"
./mvnw -Dtest=AttendanceLayerStructureTest test

Observed result

ClassNotFoundException: com.lab.labtimesheet.feature.attendance.controller.AttendanceController
ClassNotFoundException: com.lab.labtimesheet.feature.attendance.repository.AttendanceQueryRepository
Tests run: 2, Failures: 0, Errors: 2, Skipped: 0
BUILD FAILURE
Process exited 1 because the implementation still used the superseded package layout.

The account-boundary assertion was separately observed RED after the final feature package move:

./mvnw -Dtest=AttendanceLayerStructureTest test
AttendanceLayerStructureTest.attendanceDoesNotMapOrExposeAccountFeatureTables:
Expecting code to raise a throwable.
Tests run: 3, Failures: 1, Errors: 0, Skipped: 0
BUILD FAILURE
Process exited 1 because attendance still owned shadow AppUser/InternProfile entity and repository types.

GREEN

Command

Affected suite

Command and result

export JAVA_HOME=/opt/homebrew/opt/openjdk@25

External-test boundaries

This test proves source/package and dependency shape, not Spring context startup, PostgreSQL queries, MVC behavior, or the final platform account-service wiring.
