Testing Bucket Sort Implementation in hello-algo

This test suite validates the bucket sort implementation for floating-point numbers in Go, focusing on sorting values in the range [0, 1). The test ensures correct sorting behavior and output verification for the bucket sort algorithm.

Test Coverage Overview

The test coverage focuses on validating bucket sort functionality for floating-point arrays.

Tests sorting of decimal numbers between 0 and 1
Verifies correct ordering of a 10-element float64 array
Covers basic sorting functionality with sample data

Implementation Analysis

The testing approach utilizes Go’s native testing framework with a straightforward single test case structure.

Testing patterns include:

Direct function invocation with predefined test data
Visual verification through console output
Use of float64 data type for precise decimal handling

Technical Details

Testing infrastructure includes:

Go testing package (testing)
Standard fmt package for output formatting
Single test function implementation (TestBucketSort)
Float64 array initialization and manipulation

Best Practices Demonstrated

The test implementation showcases clean testing practices with focused scope.

Clear test function naming convention
Properly documented test file header
Specific input data range definition
Straightforward test case organization
