Python 使用pytest运行单元测试时出错-AttributeError:'；TestCaseFunction'；对象没有属性'；获取标记'；

我将Pytest5.4.1与Python3.6一起使用

代码：

运行

pytest

会出现以下错误：

可能是什么问题？

从错误输出中可以看出，问题出在pytest remotedata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，错误得到解决：

问题是

get\u marker

已被重命名为

get\u closest\u marker

。在GitHub上，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安装-U pytest remotedata

如果没有任何代码可供查看，很难找出问题所在，因为您正在调用get_marker（）在TestCaseFunction上，它显然没有get_marker属性。现在使用unittest代码和完整输出更新。对于我来说，它正在运行。您有什么版本的pytest cov和pytest remotedata？pytest cov==2.8.1；pytest remotedata==0.2.1

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

pip install --upgrade pytest-remotedata
