How to disable subProcess when debugging pytest code?

[natsu1375]

import pty,os
def test_pty():
  pid,fd=pty.fork()
  if pid==0:
    os.execl("/usr/bin/pwd", "pwd")
  else:
    data=os.read(fd, 1024)
    x=1  # break here

Right click the gutter icon, and select Debug Test.
You have to wait 5 seconds before hitting the breakpoint, even though the child process just executed pwd and exited immediately.
And the data returned is b'5.95s - pydevd: Sending message related to process being replaced timed-out after 5 seconds\r\n'.

So when debugging pytest code, subProcess is enabled by default.
Is there anyway to disable it?

Thanks.

In launch.json, create a configuration with purpose set to debug-test, and subProcess set to false. You don’t need to set module, program, etc.

Thanks. It works.
