Testing PostgreSQL User Management Operations in PgHero

This test suite validates PostgreSQL user management functionality in PgHero, focusing on user creation and table permissions. The tests ensure proper user creation and deletion operations while maintaining database security and access control.

Test Coverage Overview

The test suite provides comprehensive coverage of PostgreSQL user management operations.

Tests user creation with basic permissions
Validates user creation with specific table access
Ensures proper user cleanup through teardown
Verifies database-level user operations

Implementation Analysis

The testing approach employs Minitest framework with a focused unit testing strategy. The implementation uses a modular structure with teardown hooks to ensure clean test isolation.

Utilizes Minitest assertions for validation
Implements helper methods for user management
Maintains test isolation through proper teardown

Technical Details

Testing Framework: Minitest
Database Interface: Custom database wrapper
Test Helper Integration: test_helper.rb
User Management: Direct database operations
Test Environment: Isolated test database context

Best Practices Demonstrated

The test suite exemplifies several testing best practices in Ruby database testing.

Proper test cleanup through teardown methods
Isolation of test cases
Clear and consistent naming conventions
Modular test helper methods
Focused test scenarios with single responsibility
