鼻子测试正在捕获我的打印语句的输出.如何规避呢? [英] nosetests is capturing the output of my print statements. How to circumvent this?

问题描述

当我键入

$ nosetests -v mytest.py

所有测试通过时，将捕获我所有的打印输出. 我想看到打印输出，甚至一切都过去了.

all my print outputs are captured when all tests pass. I want to see print outputs even everything passes.

所以我正在做的是强制声明错误以查看输出，就像这样.

So what I'm doing is to force an assertion error to see the output, like this.

class MyTest(TestCase):

    def setUp(self):
        self.debug = False

    def test_0(self):
        a = .... # construct an instance of something
        # ... some tests statements
        print a.dump()
        if self.debug:
            eq_(0,1)

感觉太黑了，必须有更好的方法.请赐教.

It feels so hackish, there must be a better way. Enlighten me please.

推荐答案

任一:

$ nosetests --nocapture mytest.py

或者:

$ NOSE_NOCAPTURE=1 nosetests mytests.py

(也可以在nose.cfg文件中指定，请参见nosetests --help)

(it can also be specified in the nose.cfg file, see nosetests --help)
