在 pycharm/pydev 中调试 pytest 事后异常

Debugging pytest post mortem exceptions in pycharm/pydev(在 pycharm/pydev 中调试 pytest 事后异常)

问题描述

我想在不预先配置断点的情况下将 PyCharm 的内置 Pytest 运行器与调试器一起使用.

I would like to use the built in Pytest runner of PyCharm together with the debugger without pre-configuring breakpoints.

问题是我的测试中的异常被 Pytest 捕获，因此 PyCharm 的事后调试器无法处理异常.

The problem is that exceptions in my test are caught by Pytest so PyCharm's post mortem debugger cannot handle the exception.

我知道使用断点是可行的，但我不想运行我的测试两次.

I know using a breakpoint works but I would prefer not to run my test twice.

在Unittest中找到了一种方法，我想知道Pytest中是否存在类似的东西.

Found a way to do this in Unittest, I would like to know if something like this exists in Pytest.

有没有办法用PyCharm?

推荐答案

你在用 pytest-pycharm 插件?看起来它对我有用.创建virtualenv，pip install pytest pytest-pycharm，在PyCharm使用这个virtualenv Edit configuration ->Python Interpreter 然后用 Debug ... 运行示例:

Are you using pytest-pycharm plugin? Looks like it works for me. Create virtualenv, pip install pytest pytest-pycharm, use this virtualenv at PyCharm Edit configuration -> Python Interpreter and then run with Debug ... Example:

import pytest

def test_me():
    assert None

if __name__ == '__main__':
    pytest.main(args=[__file__])

PyCharm 调试器在 assert None 点停止，(, AssertionError(u'assert None',), None)

PyCharm debugger stops at assert None point, with (<class '_pytest.assertion.reinterpret.AssertionError'>, AssertionError(u'assert None',), None)

设置首选项>工具 >Python 集成工具 >默认测试运行程序 到 py.test.然后 运行 >在 test_me.py 中调试 'py.test'
