Testing Selection Sort Implementation in hello-algo

This test suite validates the implementation of Selection Sort algorithm in Go, ensuring correct sorting behavior for integer arrays. The tests verify the sorting functionality through a basic test case with duplicate elements.

Test Coverage Overview

The test coverage focuses on validating the selection sort implementation with a single test case.

Tests sorting of integer array with duplicate values
Verifies basic sorting functionality
Includes edge case of repeated elements (1 appears twice)

Implementation Analysis

The testing approach utilizes Go’s native testing package for unit testing. The implementation follows a straightforward pattern of initializing a test array, applying the sort function, and verifying results through console output.

Uses Go’s testing.T framework
Implements single test function methodology
Employs fmt package for result visualization

Technical Details

Testing Framework: Go testing package
Output Handling: fmt package for result printing
Test Function: TestSelectionSort
Input Data: Static integer array with duplicates

Best Practices Demonstrated

The test implementation shows fundamental testing practices in Go, though it could be enhanced with more robust verification methods.

Clear test function naming
Simple and focused test case
Direct verification approach
Proper package organization
