20180925-4 单元测试，结对

此作业要求参见：【https://edu.cnblogs.com/campus/nenu/2018fall/homework/2146】

结对伙伴：祝玮琦

  通过学习编写的单元测试的代码：（参考了上一届宋雨的单元测试代码，因为能力有限，只写出来针对功能1的单元测试代码）

功能1的单元测试代码：

import unittest
from gongneng1 import *

class TestDict(unittest.TestCase):

    def test_calc(self):
        print('-----开始测试-----
')
        str = ra_number()
        print(str)
        result = input('输入正确结果
>')
        self.assertEqual(int(result), my_eval(str))
        print('
-----测试结束-----')

if __name__ == '__main__':
    unittest.main()

 

运行结果如下：

因为是先写完的四则运算程序，然后写的单元测试代码。所以一次通过了。经过规范的四则运算代码如下：

 

功能1：

import random

def ra_number():
    ops = ['+', '-', '*', '/']
    s1 = random.randint(1, 10)
    s2 = random.randint(1, 10)
    s3 = random.randint(1, 10)
    s4 = random.randint(1, 10)
    op1 = random.choice(ops) #随机运算符
    op2 = random.choice(ops)
    op3 = random.choice(ops)
    while op1 == op2 == op3:
        op1 = random.choice(ops) #随机运算符
        op2 = random.choice(ops)
        op3 = random.choice(ops)
    return str(s1)+op1+str(s2)+op2+str(s3)+op3+str(s4)

def my_eval(str):
    return eval(str)


if __name__ == '__main__':
    com = input('>')  # 用户输入
    cot = 0  # 答对的题
    x = 0
    while x < 20:
        eq = ra_number()
        res = my_eval(eq)
        if len(str(res)) > 5:
            continue
        x += 1
        print(eq)
        in_res = eval(input('?'))
        if in_res == res:
            print('算对啦，你真是个天才！')
            cot += 1
        else:
            print('再想想吧，答案似乎是%s喔！' % res)

    print('你一共答对%s道题，共20道题' % cot)

功能2：

from random import choice
ops = ['+','-','*','/']
bra = ['(', '', ')']
com = input('>') #用户输入

    bra_2 = ['' , '' , '']

    while (i ==0 and ii ==2) or abs(i-ii)==1 
        or ii < i  :
        i = randint(0,2)
        ii = randint(0,2)
    bra_1[i] = '(';   bra_2[ii]=')'
    return bra_1,bra_2

    s1 = randint(1,10)
    s2 = randint(1,10)
    s3 = randint(1,10)
    s4 = randint(1,10)
    op1 = choice(ops) #随机运算符
    op2 = choice(ops)
    op3 = choice(ops)
    while op1 == op2 == op3 :
        op1 = choice(ops) #随机运算符
        op2 = choice(ops)
        op3 = choice(ops)

    (bra_1,bra_2) = bra()

    return  bra_1[0] + str(s1) + op1 + bra_1[1] + str(s2) + 
    bra_2[0] + op2 + bra_1[2] + str(s3) + bra_2[1] + op3 
    + str(s4) + bra_2[2]

while x < 20 :
    eq = ra_number()
    res = eval(eq) 
    if len(str(res) ) > 5:
        continue
    x += 1
    print(eq)
    in_res =eval( input('?'))
    if in_res == res:
        print('算对啦，你真是个天才！')
        cot += 1
    else:
        print('再想想吧，答案似乎是%s喔！'%res)

print('你一共答对%s道题，共20道题'%cot)

体会：单元测试能让我们更加规范的书写代码，可以提高代码的质量。
