Testing Container Capacity Algorithm Implementation in hello-algo

This test suite validates the maxCapacity function implementation in the hello-algo repository, focusing on container capacity calculations using a greedy algorithm approach. The tests verify the algorithm’s ability to find the maximum water volume that can be contained between vertical lines of varying heights.

Test Coverage Overview

The test coverage focuses on validating the maxCapacity function with a predefined array of heights.

Tests a single primary case with diverse height values
Verifies correct calculation of maximum water capacity
Handles multiple identical height values within the input array
Tests integration with Go’s testing framework

Implementation Analysis

The testing approach employs Go’s native testing package for unit test implementation.

The test utilizes a straightforward structure with a single test case, demonstrating the greedy algorithm’s functionality through direct function invocation and result verification. The implementation includes output formatting for result visualization using fmt.Println.

Technical Details

Uses Go’s built-in testing package
Implements TestMaxCapacity as the main test function
Utilizes fmt package for output formatting
Test file organization follows Go testing conventions
Simple setup with direct test case execution

Best Practices Demonstrated

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

Clear test function naming convention
Proper package organization
Focused test scope
Readable test data setup
Direct result verification approach
