如何将pytest的结果/日志保存到文件中？

Question

我无法尝试将pytest中显示的结果保存到文件中(txt,log,无所谓).在下面的测试示例中,我想将控制台中显示的内容捕获到某种文本/日志文件中:

import pytest
import os

def test_func1():
    assert True


def test_func2():
    assert 0 == 1

if __name__ == '__main__':

    pytest.main(args=['-sv', os.path.abspath(__file__)])

控制台输出我想保存到文本文件:

test-mbp:hi_world ua$ python test_out.py
================================================= test session starts =================================================
platform darwin -- Python 2.7.6 -- py-1.4.28 -- pytest-2.7.1 -- /usr/bin/python

test_out.py::test_func1 PASSED
test_out.py::test_func2 FAILED

====================================================== FAILURES =======================================================

    def test_func2():
>       assert 0 == 1
E       assert 0 == 1

test_out.py:9: AssertionError

看起来你的所有测试输出都是stdout,所以你只需要在那里"重定向"你的python调用输出:

python test_out.py >myoutput.log

您还可以将输出"发球"到多个位置.例如,您可能希望登录该文件,还可以在控制台上看到输出.上面的例子然后变成:

python test_out.py | tee myoutput.log
