Experimental debugger wont stop on breakpoints when debugging testcases in async-await code #2111
Description
Environment data
- VS Code version: 1.25.0
- Extension version (available under the Extensions sidebar): 2018.6.0 (20 June 2018)
- OS and version: Kubuntu 17.10, Linux 4.13.0-46
- Python version (& distribution if applicable, e.g. Anaconda): Python 3.6.3
- Type of virtual environment used (N/A | venv | virtualenv | conda | ...): pipenv
- Relevant/affected Python packages and their versions: unittest, pytest, trio, asyncio
Actual behavior
Running a test on an async function running, the debugger won't stop on breakpoints inside async functions. Tried with both unittest and pytest. Originally tested with trio event loop but the problem also occurs with asyncio, so it is not event loop specific.
It looks as if the execution stops, but you don't get an indication at all, no yellow line on the breakpoint, no stack trace, no variable inspection and shortly after the test seems to crash.
Expected behavior
Debugger stops on breakpoint inside async function.
Steps to reproduce:
Test code using pytest:
def test_content(response):
"""Sample pytest test function with the pytest fixture as an argument."""
# from bs4 import BeautifulSoup
# assert 'GitHub' in BeautifulSoup(response.content).title.string
async def test_something_async():
assert 1 == 2
trio.run(test_something_async)
I set the breakpoint on the assert line, like in the screenshot above.
