   • 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)
