Expected behaviour

Run test in debugger

gives me the following output

As you can see its not reporting the problem :-?

Steps to reproduce:

It was working until recently. I think the last auto update might have coursed it...?
Why would it not be showing the track trace?
Works fine from a terminal running python -m pytest

[karthiknadig]

@whillas can you share the debugger command from the terminal?

[ghost]

@karthiknadig not sure what you mean? I'm running the command via F5 with the launch.json as above. The complete command is above but you have to scroll right as it seems to all the environmental variables are pretended to the command. i.e.

i.e. scroll left plz

Is it specific to pytest, or are you seeing the same when trying to run e.g. a simple hello world type app?

[ghost]

yup, seems to run print("Hello world") just fine. I've setup another project and it works fine for pytest. I guess its something to do with the project and pytest. I reinstalled the later and no cigar. I can start to remove things and see if it starts to run again...?
With all tests removed it still hits this problem.
I'm guessing that the reason there is no stack trace is because pytest is capturing it. And something goes wrong between starting pytests output capture and the running of the tests...?
YES! I passed the -s and i get the following output (but don't know what it means):

collecting ... E00000.948: Exception escaped from start_client

            RuntimeError: already started

But I'm not using multiprocessing...?

[ghost]

Ok, looks like it has something to do with zeromq. Even though none of my tests are testing code related to it.
Ya, making sure the tests were not pulling in any of that code. Might also be some multi processing that going on around that code.

[int19h]

Ultimately, this will get fixed once we ship #1706.
