Testing Iteration Pattern Implementations in hello-algo

This test suite evaluates various iteration implementations in Go, focusing on different loop patterns and computational complexity analysis. The tests cover basic for loops, while loops, and nested iterations to demonstrate summing operations and traversal patterns.

Test Coverage Overview

The test suite provides comprehensive coverage of iteration patterns in Go.

Key areas tested include:

Basic for loop summation
While loop implementation variants
Nested loop traversal patterns
Multiple iteration update mechanisms

Edge cases are handled through different input values and loop termination conditions.

Implementation Analysis

The testing approach utilizes Go’s native testing framework to validate different iteration implementations. The test structure employs a single test function (TestIteration) that sequentially executes multiple iteration patterns, comparing their outputs and validating the computational logic.

Framework-specific features include:

Testing package integration
Output formatting with fmt
Multiple iteration pattern validation

Technical Details

Testing tools and configuration:

Go testing package (testing)
fmt package for output formatting
Standard Go test runner
Function-level test organization
Integer-based iteration validation

Best Practices Demonstrated

The test implementation showcases several Go testing best practices including clear test function naming, proper package organization, and comprehensive iteration pattern coverage.

Notable practices:

Consistent test function naming
Clear output formatting
Systematic iteration pattern testing
Modular test organization
