Testing Bubble Sort Algorithm Implementations in hello-algo

This test suite validates the implementation of bubble sort algorithms in Go, examining both standard and optimized versions with a flag-based approach. The tests ensure correct sorting behavior and performance characteristics of the bubble sort implementations.

Test Coverage Overview

The test coverage focuses on validating two bubble sort implementations – a standard version and a flag-optimized version.

Tests sorting of integer arrays with duplicate values
Verifies correct ordering of elements
Compares results between standard and optimized implementations
Handles arrays with mixed element positions

Implementation Analysis

The testing approach employs Go’s native testing framework to validate sorting functionality.

Uses parallel test execution for efficiency
Implements direct output verification through fmt.Println
Compares two implementation variants in a single test function
Utilizes identical input arrays for consistent comparison

Technical Details

Go testing package (testing)
fmt package for output formatting
Test runner: go test
File organization follows Go package structure
Standard Go test naming conventions

Best Practices Demonstrated

The test suite demonstrates essential Go testing practices while maintaining simplicity and clarity.

Clear test function naming
Consistent input data across implementations
Direct comparison of algorithm variants
Proper package organization
Readable output formatting
