报错信息显示是语法错误，具体原因是在HTMLTestRunner.py文件的第631行中，使用了非英文的单引号（‘），而不是英文的单引号（'）。建议把该行代码修改为使用英文的单引号，如下所示：

print(sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime))

修改后再运行代码，应该就可以正常执行了。

#导包 import requests from api.teacherAPI import teacher_sys import unittest #创建测试类 class test_teacher_sys(unittest.TestCase): def setUp(self): #实例化session self.session = requests.session() self.login = teacher_sys.login() def tearDown(self): #判断，如果session存在就关闭 if self.session: self.session.close() def test01_login_success(self): response = self.login(self.session,"guest","guest") self.assertEqual(200,response.status_code)错误详情Error Traceback (most recent call last): File "D:\pythonProject1\teachersysterm\script\script.py", line 11, in setUp self.login = teacher_sys.login() TypeError: teacher_sys.login() missing 3 required positional arguments: 'self', 'username', and 'password'，为什么出现这个错误，怎样解决

这个错误提示是因为 `teacher_sys.login()` 方法需要传入三个参数，分别是 `self`、`username` 和 `password`，但是在测试类中实例化 `self.login = teacher_sys.login()` 时没有传入这三个参数。因此，你需要修改测试类中的 `setUp()` 方法，将 `self.login` 实例化时传入正确的参数，例如：

class test_teacher_sys(unittest.TestCase):
    def setUp(self):
        # 实例化session
        self.session = requests.session()
        # 实例化登录方法，传入正确的参数
        self.login = teacher_sys.login(self.session, "guest", "guest")
    
    def tearDown(self):
        # 判断，如果session存在就关闭
        if self.session:
            self.session.close()
    
    def test01_login_success(self):
        response = self.login()
        self.assertEqual(200, response.status_code)

这样就可以正确地实例化 `self.login` 并调用登录方法了。

if __name__ == '__main__': suite = unittest.TestSuite() runner = unittest.TextTestRunner() suite.addTest(TestDemo('test_case_01')) # suite.addTest(TestDemo('test_case_02')) runner.run(suite) with open("test_report.html", "w") as f: runner = HTMLTestRunner.HTMLTestRunner(tream=f, title='Test Report', description='This is a test report generated by web') runner.run(suite) 这段代码有错误吗？

代码存在一个小错误，HTMLTestRunner 的参数名应该是 `stream` 而不是 `tream`。正确的代码如下：

if __name__ == '__main__':
    suite = unittest.TestSuite()
    runner = unittest.TextTestRunner()
    suite.addTest(TestDemo('test_case_01'))
    # suite.addTest(TestDemo('test_case_02'))
    with open("test_report.html", "w") as f:
        runner = HTMLTestRunner.HTMLTestRunner(stream=f, title='Test Report', description='This is a test report generated by web')
        runner.run(suite)

另外，如果要生成 HTML 报告，需要先安装 HTMLTestRunner 库。可以通过以下命令进行安装：

pip install html-testRunner
