web自动化报错:'TestUnit1' object has no attribute 'driver'，调试调试。

web自动化报错:'TestUnit1' object has no attribute 'driver'，大神帮忙调试调试。
代码如下：

from time import sleep ... testcase_methods = list(testcase_class. .keys()) ... wd.get('
from time import sleep

        testcase_methods = list(testcase_class.__dict__.keys())
        # 根据list的索引对testcase_methods进行排序
        test_names.sort(key=testcase_methods.index)

你把报错复制出来发给我看一下

你这儿testcase没有传driver进去，你继承的是unittest.TestCase，而你driver用的是self.driver, 但是unittest.TestCase里面是不提供的driver, 要么在driver前面不要加self, 要么在TestUnit1这个类下面定义一下driver，可以写 driver = driver
