+description: Complete test suite coverage for all chess logic components in NowChessSystems core module
+type: reference
+---
+
+## Test Suite Overview
+
+Comprehensive test coverage added for the NowChessSystems core chess module across all components.
+
+### Test Files Added
+
+1. **GameControllerTest.scala** (15 tests)
+   - Valid/invalid move handling
+   - Capture detection
+   - Turn switching
+   - Piece color validation
+   - Board state preservation
+
+2. **PieceUnicodeTest.scala** (18 tests)
+   - All 12 piece types (6 white, 6 black) unicode mappings
+   - Unicode distinctness verification
+   - Convenience constructor validation
+   - Roundtrip consistency
+
+3. **RendererExtendedTest.scala** (22 tests)
+   - Empty board rendering
+   - Single/multiple piece placement
+   - All piece types display
+   - Board dimension labels
+   - Piece placement accuracy
+   - ANSI color codes
+   - Output consistency
+   - Pawn position accuracy
+
+4. **ParserExtendedTest.scala** (41 tests)
+   - Valid file/rank/move parsing
+   - Whitespace handling
+   - Case sensitivity
+   - Boundary validation
+   - Length validation
+   - Special character rejection
+   - Edge cases (very long strings, invalid formats)
+
+5. **MoveValidatorExtendedTest.scala** (45 tests)
+   - Pawn movement (forward, double-push, captures, edge cases)
+   - Knight movement (L-shapes, corner behavior, jumps)
+   - Bishop movement (diagonals, blocking, captures)
+   - Rook movement (orthogonal, blocking, captures)
+   - Queen movement (combined rook+bishop)
+   - King movement (one-square moves, corners)
+   - legalTargets consistency with isLegal
+
+6. **MainTest.scala** (3 tests)
+   - Entry point verification
+
+### Existing Tests (Not Modified)
+
+- ModelTest.scala: 9 tests
+- ParserTest.scala: 8 tests
+- RendererTest.scala: 6 tests
+- MoveValidatorTest.scala: 25 tests
+
+### Total Test Count
+
+**144 tests** covering all major source files in modules/core:
+- All test methods properly typed `: Unit` for JUnit 5 compatibility
+- No use of `implicit` — all use modern Scala 3 `given`/`using`
+- No use of `null` — proper use of `Option`/`Either`
+- Jakarta annotations only (no javax.*)
+
+### Coverage Areas
+
+**Complete coverage of:**
+- Board representation and movement
+- All piece types and their movement rules
+- Move validation logic
+- Input parsing and validation
+- Board rendering with ANSI colors
+- Unicode piece representations
+- Edge cases and boundary conditions
+- State preservation and immutability
+
+### Build Status
+
+All tests pass with `./gradlew :modules:core:test`:
+- ✓ No compilation errors
+- ✓ No test failures
+- ✓ JaCoCo coverage reporting enabled
+- ✓ Scala 3 style compliance (fixed varargs, wildcards)
