Testing Lunar Calendar Conversion Implementation in AndroidUtilCode

This test suite validates the LunarUtils class functionality for converting between lunar and solar calendar dates in the AndroidUtilCode library. It covers core lunar calendar calculations and date conversion operations essential for applications requiring Chinese calendar support.

Test Coverage Overview

The test suite provides comprehensive coverage of lunar calendar conversions and calculations.

Key areas tested include:

Lunar year to GanZhi (Chinese sexagenary cycle) conversion
Lunar to solar date conversion
Solar to lunar date conversion

Edge cases covered include leap year handling and date boundary validations.

Implementation Analysis

The testing approach utilizes JUnit to validate core lunar calendar computations through discrete unit tests. Each test method focuses on a specific conversion function, employing direct method invocation with representative test data. The implementation leverages custom Lunar and Solar data classes for date representations.

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
Custom LunarUtils utility class
Inner Solar and Lunar data classes
System.out verification for conversion results

Best Practices Demonstrated

The test suite demonstrates clean testing practices through focused test methods and clear naming conventions. Each conversion type is tested independently, following single responsibility principle. The code organization separates different calendar conversion scenarios into distinct test cases for better maintainability.
