在pycharm / pydev中调试pytest post mortem异常 [英] Debugging pytest post mortem exceptions in pycharm/pydev

问题描述

我想使用PyCharm内置的Pytest运行器和调试器，而不需要预先配置断点。

问题是我的测试中的异常被捕获通过Pytest，PyCharm的post验证调试器无法处理异常。

我知道使用断点工作，但我不想运行我的测试两次。

在Unittest中找到一种方法，我想知道Pytest中是否存在类似的东西。

有没有办法用PyCharm捕获单元测试异常？

解决方案

您是否使用 pytest-pycharm 插件？看起来像对我有用创建virtualenv， pip install pytest pytest-pycharm ，在PyCharm中使用此virtualenv 编辑配置 - > Python解释器然后运行调试... 示例：

  import pytest 
 
 def test_me（）：
 assert无
 
如果__name__ =='__main__'：
 pytest.main （args = [__ file__]）
  

PyCharm调试器停止在断言无（< class'_pytest.assertion.reinterpret.AssertionError'>，AssertionError（u'assert None'，），None） / p>

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

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

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

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

Is there a way to catch unittest exceptions with PyCharm?

解决方案

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

EDIT

Set Preferences > Tools > Python Integration Tools > Default test runner to py.test. Then Run > Debug 'py.test in test_me.py'
