Testing LRU Abstract Map Implementation in JCSprout

This test suite validates the implementation of a custom LRU (Least Recently Used) Abstract Map in Java, focusing on basic map operations and size management. The tests verify core functionality including put, get, and remove operations while maintaining proper size tracking.

Test Coverage Overview

The test coverage focuses on fundamental map operations with the LRUAbstractMap implementation.

Key areas tested include:

Insertion of key-value pairs using put()
Retrieval of values using get()
Removal of entries using remove()
Size management and verification

Implementation Analysis

The testing approach employs JUnit 4 framework for unit testing, with additional logging functionality through SLF4J. The test structure demonstrates both standard unit test methods and a main method for manual verification.

Testing patterns include:

Sequential operation testing
Size verification after modifications
Logging of state changes

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
SLF4J logging implementation
Custom LRUAbstractMap class
Logger configuration for debugging and verification

Best Practices Demonstrated

The test implementation showcases several testing best practices:

Clear test method organization
Proper logging implementation for debugging
Separate test and manual verification methods
Sequential operation verification
State validation through size checks
