Python3.8中unittest的奇怪之处-不检测测试

这是一个非常奇怪的问题，但是Python中的

unittest

实际上并没有在测试用例中进行测试

这是我正在使用的代码，包括我正在测试的函数和我试图在

tests.py

脚本中使用的unittest代码：

import unittest
import bs4


# This is the function we're testing
def zerolength_link_test(post_contents: str) -> bool:
    # Returns 'True' if there is a zero length link in here.
    bs = bs4.BeautifulSoup(post_contents, 'html.parser')
    for link in bs.find_all('a'):
        if '<img ' in str(link):
            # Image embeds in links are not zero-length for this case.
            continue
        if len(link.text) == 0:
            return True
        if link.text.isspace() or not link.text.isprintable():
            return True

    return False


class ZeroLengthLinkTests(unittest.TestCase):

    def whitespace_only_link(self):
        test = 'This is a test at <a href="https://google.com"> </a> whitespace-only ' \
               'links which are effectively zero-length.'
        self.assertTrue(zerolength_link_test(test))

    def zero_length_link_nonobfuscated(self):
        test = "This is a test of <a href='google.com'></a> actual zero-length link text."
        self.assertTrue(zerolength_link_test(test))

    def zero_length_link_tag_obfuscation(self):
        test = "This is a test of <a href='google.com'><em></em></a> z" \
               "ero length links obfuscated by tags."
        self.assertTrue(zerolength_link_test(test))

    def unprintable_only_link(self):
        test = "This one has unprintable characters <a href='google.com'>\t\f\r\n</a> in the link."
        self.assertTrue(zerolength_link_test(test))

    def not_zero_length_link(self):
        test = "This is a test of <a href='https://google.com'>an actual link to " \
               "Google</a> that is not Zero Length."
        self.assertFalse(zerolength_link_test(test))

    def whitespace_only_link_tag_obfuscation(self):
        test = "This is a test of a whitespace only link <a href='google.com'><span> </span></a>" \
               " obfuscated with span tags."
        self.assertTrue(zerolength_link_test(test))

    unittest.main()

#这是我们正在测试的功能
def zerolength链接测试（post内容：str）->bool:
#如果此处存在长度为零的链接，则返回“True”。
bs=bs4.BeautifulSoup（post_内容'html.parser'）
对于bs.find_all（'a'）中的链接：
如果'：

这三个单独的测试是用名称以字母test开头的方法定义的。此命名约定通知测试运行程序哪些方法表示测试

如果“我认为你的每个测试方法都应该被命名为：
test.*
”，那么我现在觉得自己很愚蠢。谢谢。没问题，生活中每个程序员都会遇到pal@ThomasWard
