Add unit tests for ComponentInstance module

[vipul-09]

Related Issues

Improves test coverage for the schematic converter by adding automated unit tests for the ComponentInstance module. These tests verify component parsing and KiCad output generation, helping detect regressions during future development.

Purpose

The main objective is to improve the test coverage of the schematic converter by adding automated unit tests for the ComponentInstance module. These tests verify correct parsing of component information, default attribute generation, attribute handling, orientation handling, and generation of KiCad-compatible output.

Approach

Created a pytest-based test suite under:

unit_tests/test_component_instance.py

The following functionality is covered:

• Parsing basic component properties
• Default PKGREF attribute generation
• Default VALUE attribute generation
• Parsing PKGREF attribute
• Parsing VALUE attribute
• Parsing DC attribute
• Parsing GAIN attribute
• Verifying generated output from ComponentInstance.print()
• Verifying component block generation
• Verifying field headers
• Verifying reference and value output
• Verifying unit line generation
• Verifying all supported orientations:
