Add returncode argument to pytest.exit#4145

If the argument is not None, it'll raise a SystemExit exception to cleanly exit pytest.
It checks that a SystemError was raised and the SystemError code is the same as the returncode argument.

Thanks @cacoze for the PR!
Please take a look at my comments. 👍

I think we should always raise Exit, but pass the argument along to it: Exit(msg, returncode), and treat it accordingly in main.py:
Lines 185 to 188 in 7e1fac5
Like this:
existstatus = EXIT_INTERRUPTED
if initstate < 2 and isinstance(excinfo.value, exit.Exception):
sys.stderr.write("{}: {}\n".format(excinfo.typename, excinfo.value.msg))
exitstatus = excinfo.value.exitstatus
config.hook.pytest_keyboard_interrupt(excinfo=excinfo)
session.exitstatus = exitstatusThere was a problem hiding this comment.
Also, please update the docstring for pytest.exit

Following my suggestion above, this will need to be changed to a test using testdir, something like:
def test_pytest_exit_returncode(testdir):
testdir.makepyfile("""
import pytest
def test_foo():
pytest.exit("some exit msg", 99)
""")
result = testdir.runpytest()
assert result.ret == 99

I think this reads better:
Add

Thanks for the feedback @nicoddemus . I'm still learning about the project and had no idea that I could use _pytest/main.py to set the return code from the test. |

Please add returncode to the end of the parameter list to keep backward compatibility; technically users should not raise this explicitly, but it doesn't hurt to keep compatibility in this case.

While we're at it, please add a description for the msg parameter as well:
:param str msg: message to display upon exit.

Also there's an extra period at the end of this sentence.

Just a btw from reading commits on master: squashing this would have made a lot of sense. |
