我在包含the capfd
fixture的测试中运行ipdb
时遇到问题。测试代码的缩减版本如下:
import pytest
import sys
def test_foo(capfd):
def foo():
print("Hello World!")
foo()
out, err = capfd.readouterr()
import ipdb
ipdb.set_trace()
assert out == "Hello World!\n"
当我运行py.test -s test/test_capfb.py
时,调试器的所有输出都被捕获,我什么也看不见。我仍然可以向调试器发出命令(例如下面输出中的c
),但在整个过程完成运行之前不会输出。输出的样本在这里:
; py.test -s tests/test_capfb.py

有没有办法让pytest
在涉及ipdb
时停止捕获stdout / stderr?
答案 0 :(得分:0)
作为一种解决方法,我可以使用iocapture来捕获输出:
import pytest
import sys
import iocapture
def test_foo():
def foo():
print("Hello World!")
out = None
with iocapture.capture() as captured:
foo()
out = captured.stdout
import ipdb
ipdb.set_trace()
assert out == "Hello World!\n"
