Testing Bucket Sort Algorithm Implementation in hello-algo

This test suite validates the bucket sort algorithm implementation in Go, focusing on sorting floating-point numbers in the range [0, 1). The test ensures correct sorting behavior and algorithm functionality through unit testing.

Test Coverage Overview

The test coverage focuses on validating the bucket sort implementation with floating-point numbers.

Tests sorting of 10 floating-point numbers between 0 and 1
Verifies correct ordering of elements after sorting
Covers basic functionality of the bucket sort algorithm

Implementation Analysis

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

Uses testing.T for test execution and assertion handling
Implements direct output verification through fmt.Println
Focuses on single test case validation with predefined input array

Technical Details

Testing infrastructure leverages Go’s standard testing tools and patterns.

Go testing package (testing)
fmt package for output formatting
Standard Go test execution environment
No external testing dependencies required

Best Practices Demonstrated

The test implementation showcases fundamental Go testing practices.

Clear test function naming following Go conventions
Proper package organization and file structure
Self-contained test case with defined input data
Documentation including creation time and authorship
