Validating Symmetric Encryption Operations in eladmin

This test suite validates the EncryptUtils class functionality in the eladmin project, focusing on symmetric encryption and decryption operations using DES algorithm. The tests ensure reliable data encryption and decryption mechanisms for secure data handling.

Test Coverage Overview

The test suite provides comprehensive coverage of symmetric cryptographic operations.

Key areas tested include:

DES encryption of string input to hexadecimal output
DES decryption of hexadecimal strings back to original text
Verification of encryption-decryption cycle integrity
Exception handling for cryptographic operations

Implementation Analysis

The testing approach utilizes JUnit Jupiter framework with focused unit tests for each cryptographic operation. The implementation employs assertion-based verification to ensure the encryption and decryption results match expected values.

The tests demonstrate a clear separation of concerns, testing encryption and decryption operations independently while maintaining consistent test data across the suite.

Technical Details

Testing tools and configuration:

JUnit Jupiter test framework
Static imports for assertion methods
EncryptUtils class utility methods
Exception handling wrapper for cryptographic operations
Hexadecimal string verification for encrypted output

Best Practices Demonstrated

The test suite exhibits several testing best practices and quality patterns.

Notable practices include:

Clear test method naming reflecting functionality under test
Isolated test cases for each cryptographic operation
Consistent test data across related operations
Proper exception handling and verification
Clear documentation with method purpose annotations
