我该如何为此类编写单元测试？

Question

因此，我对编写单元测试非常陌生，我需要一些有关如何为已编写的类编写单元测试的指南。 任何帮助将不胜感激，谢谢！ 另外，我想用pycharm编写单元测试。

class StringProcessor:
    def __init__(self, yo="", a="", b="", f=""):
        self.yo = yo
        self.a = a
        self.b = b
        self.f = f

    def my_first_test(self):
        yo = input("Enter your string here")
        ya = yo.split()
        even = 0
        odd = 0
        for i in ya:
            if len(i) % 2 == 0:
                even = even + 1
            else:
                odd = odd + 1
        print("The number of odd words are ", odd)
        print("The number of even words are", even)

    def my_second_test(self, a, b):
            d = a.split()
            print("The word", b, "is repeated: ", d.count(b), "times")

    def my_third_test(self, f):
        d = {}
        lst = f.split()
        for c in lst:
            d[c] = lst.count(c)
        for key,value in d.items():
            print(key, ":", value)

您必须将用户输入与类分开以使其可测试。

您在这里不需要上课，仅需要字典和一些功能。

另外，恕我直言，用户输入是有害的，请改用sys.argv 。
