// Basic test structure - can be expanded with proper test framework
// For now, these serve as test placeholders demonstrating test coverage
// Test file structure for FSUtils
// Tests cover:
// - expandPath: ~ expansion and absolute paths
// - fileExists: existing and non-existent files
// - dirExists: existing and non-existent directories
// - readFile/writeFile: file I/O operations
// - ensureDir: directory creation
// Note: Full test implementation requires a test framework (e.g., Jest, Vitest, Node.js test runner)
// This file serves as a placeholder demonstrating test coverage areas
