我在 Visual Studio 2019(版本16.3.9)中有一个现有的Python项目，其中包含在 Visual Studio 2017 下为unittest.py创建的单元测试。我已经为unittest配置了该项目，因为这是在Visual Studio 2019中需要的:
但是没有显示单元测试。
但我收到以下错误:

translate_non_printable = getattr(_pytest.compat, "_translate_non_printable")
AttributeError: module '_pytest.compat' has no attribute '_translate_non_printable'
最佳答案
您可以检查“测试”下的输出窗口中传递给 run_adapter.py 的参数，并确保在那里发现 unittest 吗？
示例
xxx\EXTENSIONS\MICROSOFT CORPORATION\PYTHON\16.0.0\PythonFiles\testing_tools\run_adapter.py discover unittest --output-file xx\Local\Temp\tmpF743.tmp -- . test*.py
您的环境中是否安装了 pytest？如果是的话哪个版本？
