Test Coverage, CLAUDE Compliance, and a Safer Codebase

Today’s focus was on strengthening Stellar Throne's internal validation pipeline and ensuring the project continues to scale cleanly under AI-assisted development.


✅ What Got Done

  • ✅ Improved Unit Test Coverage
    Identified gaps in existing test coverage, especially from earlier Claude-generated files. Added new test cases for key game systems, including colony construction, combat state transitions, and shipyard logic.

  • ✅ Test Counting & Verification System
    Built a utility that compares registered test modules against the actual file count. This prevents “orphaned” tests — where Claude writes a test but forgets to register it. It’s now part of the daily validation workflow.

  • ✅ CLAUDE.md Audit
    Completed a pass over the codebase to verify:

    • Naming conventions (camelCase)

    • File structure adherence

    • Token-safe module boundaries

    • AI prompt formatting patterns
      CLAUDE.md remains aligned with the project as of today.


💡 What I Learned

The test coverage illusion was subtle but dangerous — having tests written but not run creates a false sense of safety. Fixing this now saves major debugging headaches later. Also, AI output policies need reinforcement: it's easy for a helper like Claude to silently skip crucial steps unless expectations are made explicit and checked automatically.

The Case of the Missing Unit Tests

Today’s development revealed an important oversight: while Claude had been generating unit tests for various systems, they weren’t being added to the test runner. As a result, many validations were silently unused — giving a false sense of coverage.


🧪 What Got Done

  • ✅ Improved Unit Test Coverage:

    • Identified and integrated previously orphaned tests

    • Updated the main test runner to explicitly include all test modules

    • Improved unit test coverage


🔍 What I Learned

AI can produce great utility code, but it doesn’t always connect the dots — especially when it comes to integration. Even if a file looks complete, it may not be registered in the larger test framework. Always verify that generated tests are executed, not just written.
