# Example of how to use VS Code debugger with Locust.
# Make sure you set "gevent": true in your launch.json

# In recent versions of VSCode you might get the following warning. I dont know why, but it seems safe to ignore.
#
# PYDEV DEBUGGER WARNING:
# sys.settrace() should not be used when the debugger is being used.
# This may cause the debugger to stop working correctly.
# If this is needed, please check:
# http://pydev.blogspot.com/2007/06/why-cant-pydev-debugger-work-with.html
# to see how to restore the debug tracing back correctly.
#
# (if you know why this happens, please let me know :)
