Testing Radix Sort Algorithm Implementation in hello-algo

This test suite validates the implementation of Radix Sort algorithm in Go, focusing on sorting large integers through a digit-by-digit approach. The tests ensure proper sorting functionality while demonstrating Go’s testing capabilities for algorithmic implementations.

Test Coverage Overview

The test coverage focuses on validating the radix sort implementation with multi-digit integers.

Tests large integer array sorting
Validates sorting stability
Covers numbers with varying digit lengths
Ensures proper handling of 8-digit integers

Implementation Analysis

The testing approach utilizes Go’s built-in testing package to verify radix sort functionality. The implementation employs a straightforward test case with a predefined array of large integers, demonstrating the algorithm’s ability to sort numbers by processing each digit position.

Uses Go’s testing.T framework
Implements single test function methodology
Includes console output for verification

Technical Details

Testing Framework: Go’s native testing package
Test Runner: go test command
Output Format: fmt package for result visualization
Test File Structure: Standard Go test file organization

Best Practices Demonstrated

The test implementation follows Go testing conventions while maintaining clarity and purpose.

Clear test function naming
Proper package organization
Focused test scope
Documented test cases
Consistent code formatting
