visualstudio_py_testlauncher.py - format_exception() missing 3 required positional arguments: 'etype', 'value', and 'tb' #3305
Description
I got an exception while trying to debug a unittest. The exception was from a bug in VSCode Python extension itself:
Exception has occurred: TypeError
format_exception() missing 3 required positional arguments: 'etype', 'value', and 'tb'
File "C:\Users\Ark\.vscode\extensions\ms-python.python-2018.9.2\pythonFiles\PythonTools\visualstudio_py_testlauncher.py", line 344, in main
pass
File "C:\Users\Ark\.vscode\extensions\ms-python.python-2018.9.2\pythonFiles\PythonTools\visualstudio_py_testlauncher.py", line 347, in <module>
main()
I looked at the extension's code and the error is correct. See DonJayamanne@3e50a68#r31258938
Environment data

Hello! I have reviewed this issue and given the architectural changes of the testing rewrite, this issue should no longer exist on the rewrite. Therefore I am going to close this issue but please comment or open a new issue if you are still seeing a problem when you try this yourself!
To use the rewrite yourself just add
”python.experiments.optInto": ["pythonTestAdapter"]to your user settings. You can confirm you have the rewrite enabled by setting your log level to trace, via theDeveloper: Set Log Levelcommand in the command palette. Then check to see ifExperiment 'pythonTestAdapter' is activeis in your python logs.Thanks!
