要测试Python数独类,可以按照以下步骤进行:
以下是一个示例的测试代码:
import unittest
from sudoku import Sudoku
class SudokuTest(unittest.TestCase):
def test_solved_sudoku(self):
# 已经解决的数独
puzzle = [
[5, 3, 4, 6, 7, 8, 9, 1, 2],
[6, 7, 2, 1, 9, 5, 3, 4, 8],
[1, 9, 8, 3, 4, 2, 5, 6, 7],
[8, 5, 9, 7, 6, 1, 4, 2, 3],
[4, 2, 6, 8, 5, 3, 7, 9, 1],
[7, 1, 3, 9, 2, 4, 8, 5, 6],
[9, 6, 1, 5, 3, 7, 2, 8, 4],
[2, 8, 7, 4, 1, 9, 6, 3, 5],
[3, 4, 5, 2, 8, 6, 1, 7, 9]
]
expected_solution = puzzle # 已经解决的数独结果是其本身
sudoku = Sudoku(puzzle)
solution = sudoku.solve()
self.assertEqual(solution, expected_solution)
def test_unsolved_sudoku(self):
# 未解决的数独
puzzle = [
[5, 3, 0, 0, 7, 0, 0, 0, 0],
[6, 0, 0, 1, 9, 5, 0, 0, 0],
[0, 9, 8, 0, 0, 0, 0, 6, 0],
[8, 0, 0, 0, 6, 0, 0, 0, 3],
[4, 0, 0, 8, 0, 3, 0, 0, 1],
[7, 0, 0, 0, 2, 0, 0, 0, 6],
[0, 6, 0, 0, 0, 0, 2, 8, 0],
[0, 0, 0, 4, 1, 9, 0, 0, 5],
[0, 0, 0, 0, 8, 0, 0, 7, 9]
]
expected_solution = [
[5, 3, 4, 6, 7, 8, 9, 1, 2],
[6, 7, 2, 1, 9, 5, 3, 4, 8],
[1, 9, 8, 3, 4, 2, 5, 6, 7],
[8, 5, 9, 7, 6, 1, 4, 2, 3],
[4, 2, 6, 8, 5, 3, 7, 9, 1],
[7, 1, 3, 9, 2, 4, 8, 5, 6],
[9, 6, 1, 5, 3, 7, 2, 8, 4],
[2, 8, 7, 4, 1, 9, 6, 3, 5],
[3, 4, 5, 2, 8, 6, 1, 7, 9]
]
sudoku = Sudoku(puzzle)
solution = sudoku.solve()
self.assertEqual(solution, expected_solution)
def test_invalid_sudoku(self):
# 无解的数独
puzzle = [
[5, 3, 4, 6, 7, 8, 9, 1, 2],
[6, 7, 2, 1, 9, 5, 3, 4, 8],
[1, 9, 8, 3, 4, 2, 5, 6, 7],
[8, 5, 9, 7, 6, 1, 4, 2, 3],
[4, 2, 6, 8, 5, 3, 7, 9, 1],
[7, 1, 3, 9, 2, 4, 8, 5, 6],
[9, 6, 1, 5, 3, 7, 2, 8, 4],
[2, 8, 7, 4, 1, 9, 6, 3, 5],
[3, 4, 5, 2, 8, 6, 0, 7, 9] # 最后一行缺少一个数字
]
sudoku = Sudoku(puzzle)
solution = sudoku.solve()
self.assertIsNone(solution) # 无解的数独返回None
if __name__ == '__main__':
unittest.main()
以上示例代码展示了如何编写测试用例来测试数独类。根据这些测试用例,可以使用Python的unittest模块或其他测试框架来执行测试,并验证数独类的功能是否正常工作。对于每个测试用例,通过断言来验证实际的解决结果与期望的解决结果是否一致。如果测试通过,则说明数独类的实现是正确的;如果测试失败,则需要检查代码并修复问题。
