Implementation Summary: Issues #88-91

Overview

Successfully implemented all four issues sequentially with comprehensive testing, improved build/deploy scripts, and CI/CD integration.

Issue #88: Contracts Testing — Unit Tests for Shared Contract

Status: ✅ Complete

Summary: The Shared contract already had comprehensive unit tests covering all requirements. Tests verified:

  • ✅ test_initialize_sets_admin - Admin initialization
  • ✅ test_assign_role_by_admin_succeeds - Role assignment by admin
  • ✅ test_non_admin_cannot_assign_role - Non-admin rejection
  • ✅ test_has_role_returns_correct_boolean - Role verification for all roles
  • ✅ test_has_permission_for_each_role_permission_combination - Permission matrix testing
    • Admin: all permissions
    • Instructor: CreateCourse, EnrollStudent
    • Student: no permissions
  • ✅ test_non_admin_cannot_upgrade - Reentrancy/upgrade guard

Files:

  • contracts/shared/src/tests.rs - Existing comprehensive test suite
