Ivan Brko Panoptes Test Coverage

Test Coverage Skill

Analyze test coverage and identify modules needing tests.

Steps

1. Run all tests and collect results

   cargo test 2>&1
   

   Note total test count and any failures.

2. Identify modules without tests Search for Rust source files and check for #[cfg(test)] blocks:

   # Find files without test modules
   for f in src/**/*.rs; do
     if ! grep -q '#\[cfg(test)\]' "$f" 2>/dev/null; then
       echo "$f"
     fi
   done
   

3. Analyze untested modules For each untested module, identify:

   • Public functions that should have unit tests
   • Complex logic that would benefit from testing
   • Edge cases in the implementation

4. Generate coverage report Report modules by priority:

   • Critical: Core logic (session management, state transitions)
   • High: Input handling, navigation logic
   • Medium: Utility functions, helpers
   • Low: Simple structs, trivial implementations

Coverage Categories

Modules that SHOULD have tests

• State management (app/state.rs, session/mod.rs)
• Business logic (filters, calculations, validations)
• Type conversions and parsing
• Navigation and routing logic

Modules that MAY skip tests

• Pure TUI rendering (requires integration testing)
• PTY interaction (requires real terminal)
• Simple re-exports and type aliases

Example Report

Test Coverage Report:

Total tests: 261
Modules with tests: 26/42 (62%)

High Priority Gaps:
- src/input/dispatcher.rs - No direct tests (routes to handlers)
- src/input/session_mode.rs - No tests (PTY interaction)

Medium Priority Gaps:
- src/tui/views/*.rs - Rendering modules (integration tests recommended)

Coverage by Area:
- Core (app, session, hooks): 80%
- Input handling: 40%
- TUI rendering: 20%
- Utilities: 90%

Suggestions

After running this skill, consider:

1. Adding unit tests to high-priority gaps
2. Creating integration test scaffolding for TUI tests
3. Adding property-based tests for parsing/filtering logic
