🧪 [Core] Improve Test Coverage #120

Description

@ahmdkaml

✨ Overview

Increase automated test coverage across TextForge to ensure that core document behavior remains reliable as the application and its module architecture continue to grow.

The goal is not simply to maximize a coverage percentage, but to ensure that important behavior and architectural boundaries are protected by meaningful tests.

🎯 Goals

  • Identify important untested areas of the application.
  • Add tests for core document behavior.
  • Add tests for module and submodule behavior.
  • Add tests for templates and feature configuration.
  • Add tests for serialization and deserialization.
  • Add tests for rendering and preview behavior.
  • Add tests for document editing operations.
  • Add tests for validation and error conditions.
  • Add regression tests for previously fixed bugs.

📦 Requirements

Tests should cover important behavior including:

Document

  • Modules
  • Features
  • Submodules
  • Templates
  • Editing Operations
  • Validation
  • Serialization
  • Rendering

Tests should verify both expected behavior and important edge cases.

Where practical, tests should be focused on the appropriate architectural layer rather than testing implementation details.

📊 Coverage

Establish a way to measure test coverage and use the results to identify significant gaps.

Coverage percentage should be treated as an indicator rather than the sole success criterion. Critical functionality should have meaningful behavioral tests even when it is already counted as covered.

🚫 Out of Scope

  • Rewriting existing production code solely to increase the coverage percentage.
  • Requiring every line of UI code to have a unit test.
  • Testing implementation details that provide little protection against regressions.

🌱 Future Direction

Test coverage should grow alongside new Core features and major application functionality so that new behavior does not continually increase the untested surface of the project.
