### Question:
Position { public void incrementColumn() { column++; } Position(int line, int column);  Position(Position position); void incrementLine(); void incrementColumn(); void set(Position newPosition); int getColumn(); String getColumnAsString(); int getLine(); String getLineAsString(); String toString();  }### Answer:
@Test public void testIncrementColumn() { Position position = new Position(1, 1); for (int i = 0; i < 11; i++) { position.incrementColumn(); } assertEquals("line", 1, position.getLine()); assertEquals("lineAsString", "1", position.getLineAsString()); assertEquals("col", 12, position.getColumn()); assertEquals("colAsString", "12", position.getColumnAsString()); }
