Testing LinkedList Node Operations in hello-algo

This test suite validates the core functionality of LinkedList operations in Go, focusing on array-to-list conversion and list printing capabilities. It demonstrates essential linked list manipulation and traversal testing patterns.

Test Coverage Overview

The test coverage focuses on fundamental LinkedList operations with array integration.

Key areas tested include:

Array to LinkedList conversion validation
LinkedList traversal and printing functionality
Data integrity verification during conversion
Node connection validation

Implementation Analysis

The testing approach utilizes Go’s native testing framework with a focus on single-responsibility test cases.

Implementation highlights:

Direct array-to-list conversion testing
Output validation through print function
Clean test structure following Go conventions
Simplified test case organization

Technical Details

Testing infrastructure includes:

Go testing package (testing.T)
Custom LinkedList implementation
Array conversion utilities
Print functionality for validation
Standard Go test runner configuration

Best Practices Demonstrated

The test suite exemplifies Go testing best practices through clear organization and focused test cases.

Notable practices include:

Single test function scope
Clear input data preparation
Explicit test case naming
Focused functionality validation
Simple and maintainable test structure
