Testing Radix Sort Implementation in hello-algo

This test suite validates the implementation of Radix Sort algorithm in Go, focusing on sorting large integers through digit-by-digit processing. The tests demonstrate the effectiveness of radix sort for handling multi-digit numerical values while maintaining algorithmic efficiency.

Test Coverage Overview

The test coverage focuses on validating the radix sort implementation with large integer values.

Tests sorting of 10-digit integers
Verifies correct ordering of numbers with varying digit lengths
Validates the stability of the sorting algorithm
Ensures proper handling of multiple occurrences of same-digit values

Implementation Analysis

The testing approach utilizes Go’s built-in testing framework to validate the radix sort algorithm.

Implements single test function TestRadixSort
Uses slice manipulation for array sorting
Employs fmt package for result verification
Demonstrates Go’s testing conventions and patterns

Technical Details

Testing infrastructure leverages Go’s standard testing tools.

Uses testing package (testing.T)
Implements test function with proper Go naming conventions
Utilizes fmt package for output formatting
Follows Go project structure conventions

Best Practices Demonstrated

The test implementation showcases several Go testing best practices.

Clear test function naming following Go conventions
Proper package organization
Documented test cases with clear input data
Structured error reporting and output formatting
