Testing Heap Sort Algorithm Implementation in hello-algo

This test suite validates the implementation of heap sort algorithm in Go, focusing on sorting array operations and verification of the sorting results. The tests ensure proper functionality of heap-based sorting with various input scenarios.

Test Coverage Overview

The test coverage focuses on validating the heap sort implementation with integer arrays.

Key areas tested include:

Basic sorting functionality with mixed integers
Handling of duplicate elements (1 appears twice)
Array transformation verification

Integration points include the heap sort function interface and array manipulation.

Implementation Analysis

The testing approach utilizes Go’s native testing framework with a straightforward test case structure. The implementation employs the testing.T struct for test execution and uses fmt for output verification.

Testing patterns include:

Direct function invocation with pointer parameters
Visual output verification using fmt.Println
Single test case demonstration with mixed data types

Technical Details

Testing tools and configuration:

Go testing package (testing)
Standard fmt package for output
Pointer-based array manipulation
Traditional test function naming convention (TestHeapSort)
Local test execution environment

Best Practices Demonstrated

The test implementation showcases fundamental Go testing practices while maintaining simplicity.

Notable practices include:

Clear test function naming
Direct verification approach
Proper parameter passing mechanisms
Structured test organization
Use of appropriate Go testing conventions
