[TEST] Add Quick Evaluation Tests

[keceli]

Description

Implement quick evaluation tests to ensure the application's functionality and performance. These tests should be easy to run and provide immediate feedback on whether core components are working as expected. In addition to correctness, basic performance benchmarks should be established to detect regressions over time.

Tasks

• Create basic test suite
• Add more unit tests for core functionality
• Implement integration tests
• Add performance benchmarks

Acceptance Criteria

• All tests pass successfully
• Core functionality is covered by tests
• Performance benchmarks are established
• Documentation for tests is clear

Additional Context

This task will enhance the reliability and maintainability of the application by enabling fast and automated evaluation of changes. These tests can also serve as a foundation for CI/CD integration.
