pytest + xdist而不捕获输出? [英] pytest + xdist without capturing output?

问题描述

我正在使用pytest和pytest-xdist进行并行测试运行.在运行测试时，似乎不赞成使用-s选项将标准输出传递给终端.有什么办法可以做到这一点?我意识到这可能会导致来自不同进程的输出在终端中混乱，但是我可以接受.

I'm using pytest with pytest-xdist for parallel test running. It doesn't seem to honour the -s option for passing through the standard output to the terminal as the tests are run. Is there any way to make this happen? I realise this could cause the output from the different processes to be jumbled up in the terminal but I'm ok with that.

推荐答案

我找到了一种解决方法，尽管不是完整的解决方案.通过将stdout重定向到stderr，将显示打印语句的输出.这可以通过一行Python代码来完成:

I found a workaround, although not a full solution. By redirecting stdout to stderr, the output of print statements is displayed. This can be accomplished with a single line of Python code:

sys.stdout = sys.stderr

如果放在conftest.py中，则适用于所有测试.

If placed in conftest.py, it applies to all tests.
