Question

我正在将pytest 5.4.1和python 3.6一起使用

代码：

import unittest

class TestStringMethods(unittest.TestCase):

    def test_upper(self):
        self.assertEqual('foo'.upper(), 'FOO')

if __name__ == '__main__':
    unittest.main()

运行pytest会出现以下错误：

可能是什么问题？

Answer 1

问题在于get_marker已重命名为get_closest_marker 。在GitHub上的this issue中，您可以看到@arvindpdmn建议将pytest-remotedata==0.3.0升级到pytest-remotedata==0.3.2，因此，假设您使用pip安装依赖项，请运行以下命令：

pip install -U pytest-remotedata

Answer 2

从错误输出中可以看出，问题出在pytest-remotedata软件包中。

AttributeError: 'TestCaseFunction' object has no attribute 'get_marker'

c:\program files (x86)\microsoft visual studio\shared\anaconda3_64\lib\site-packages\pytest_remotedata\plugin.py:59: AttributeError

将pytest-remotedata软件包升级到最新版本（0.3.2）后，该错误已解决：

pip install --upgrade pytest-remotedata

使用pytest运行单元测试时出错-AttributeError：“ TestCaseFunction”对象没有属性“ get_marker”
