老师，麻烦看下这是什么问题

Question

from test_case.business.register_business import RegisterBusiness
import unittest
import HtmlTestRunner
import os

class FirstCase(unittest.TestCase):
""“
case层
”""

def setUp(self):
    self.register_b = RegisterBusiness('chrome')

def tearDown(self):
    print("case后置条件")

def test_register_email_error(self):
    email_error = self.register_b.register_email_error('qwe', '程柔位', '123456', '23456')
    self.assertFalse(email_error, 'case执行')  # 断言是否为false

@unittest.skip("不执行这一条")
def test_register_username_error(self):
    name_error = self.register_b.register_name_error('[e-mail]', '1', '123456', '23456')
    self.assertFalse(name_error)

@unittest.skip("不执行这一条")
def test_register_password_error(self):
    password_error = self.register_b.register_password_error('[e-mail]', 'chengtouwei', '1234', '23456')
    self.assertFalse(password_error)

@unittest.skip("不执行这一条")
def test_register_code_error(self):
    code_error = self.register_b.register_code_error('[e-mail]', 'chengtouwei', '123456', '23456')
    self.assertFalse(code_error)

def test_register_success(self):
    success = self.register_b.register_succes('[e-mail]', 'chengtouwei', '123456', '23456')
    self.assertTrue(success)

if name == ‘main’:
f_path = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(file))))
file_path = os.path.join(f_path + “/report/” + ‘first_case.html’)
f = open(file_path, “wb”)
# unittest.main()
suite = unittest.TestSuite()
suite.addTest(FirstCase(‘test_register_email_error’))
# unittest.TextTestRunner().run(suite)
run = HtmlTestRunner.HTMLTestRunner(stream=f, report_title=“this is first report”, descriptions=u"这个是测试报告",
verbosity=2)
run.run(suite)

运行结果

版本不一样了, 参考这个 https://www.pianshen.com/article/7550408895/  我已经解决了.

现在 HtmlTestRunner 的形参已经变了. 

不用自己创建目标文件了.

  C:\Users\tedu\AppData\Local\Programs\Python\Python39\Lib\site-packages\HtmlTestRunner\result.py

  不自己创建目标文件，你的报告生成在哪里呀

• 慕容吉运 回复 Nancy胡 #3

  默认当前文件夹下会生成一个reports文件夹，里面会生成带时间戳的报告

同学，我把f = open(file_path, “wb”)换成f = open(file_path, "w",encoding='utf-8')，报错没有了，注意是把“wb”换成了“w”，添加encoding是为了解决报告里的中文乱码

• Mushishi #1

  哈哈，不错不错 加油。

• 慕容吉运 #2

  谢谢, 用你的方法解决了, wb 和 w 具体指的是什么含义?

• 慕容吉运 #3

  好像报告就变丑了

TypeError: a bytes-like object is required, not ‘str’

你看你htmltestrunner是不是使用得python2 版本 而不是python3版本

• Nancy胡 #1

  遇到和这位同学一样的问题，我的HTMLTestRunner是专门选了-python3的

• Nancy胡 #2

  ok test04 (__main__.TestCase)
  ok test02 (__main__.TestCase)
  Traceback (most recent call last):
    File "D:/PycharmProjects/apitestProject/testCase/unittest_case.py", line 60, in <module>
      runner.run(suite)
    File "D:\envs\apitestProject\lib\site-packages\HTMLTestRunner\HTMLTestRunner.py", line 631, in run
      self.generateReport(test, result)
    File "D:\envs\apitestProject\lib\site-packages\HTMLTestRunner\HTMLTestRunner.py", line 691, in generateReport
      self.stream.write(output)
  TypeError: a bytes-like object is required, not 'str'
