问题描述
这是一个简单的测试文件:
# test_single.pydef test_addition():二加二还是四"断言 2 + 2 == 4def test_addition2():一加一还是二"断言 1 + 1 == 2
py.test 中的默认输出就像
$ py.test test_single.py -v[...]test_single.py::test_addition PASSEDtest_single.py::test_addition2 PASSED
我想要
二加二还是四 PASSED一加一还是二PASSED
即使用文档字符串作为测试的描述.
我尝试在 conftest.py
文件中使用自定义:
导入pytest@pytest.mark.tryfirstdef pytest_runtest_makereport(item, call, __multicall__):# 执行所有其他钩子以获取报告对象rep = __multicall__.execute()if rep.when == "call":额外 = item._obj.__doc__.strip()rep.nodeid = 额外退货代表
这很接近,但它在每一行重复文件名:
$ py.test test_single.py======================================================================================== 测试会话开始 ==========================================================================================平台达尔文 -- Python 2.7.7 -- py-1.4.26 -- pytest-2.6.4插件:greendots、osxnotify、pycharm收集了 2 件物品test_single.py而且二加二还是四.test_single.py而且一加一还是二.====================================================================================== 2 在 0.11 秒内通过 ========================================================================================
如何避免输出中带有 test_single.py
的行,或者只打印一次?
查看 py.test 的源代码及其一些插件没有帮助.
我知道
如果您省略了文档字符串,将使用类/函数名称.
Here is a simple test file:
# test_single.py
def test_addition():
"Two plus two is still four"
assert 2 + 2 == 4
def test_addition2():
"One plus one is still two"
assert 1 + 1 == 2
The default output in py.test is like
$ py.test test_single.py -v
[...]
test_single.py::test_addition PASSED
test_single.py::test_addition2 PASSED
I would like to have
Two plus two is still four PASSED
One plus one is still two PASSED
i.e. use the docstrings as descriptions for the tests.
I tried to use a customization in a conftest.py
file:
import pytest
@pytest.mark.tryfirst
def pytest_runtest_makereport(item, call, __multicall__):
# execute all other hooks to obtain the report object
rep = __multicall__.execute()
if rep.when == "call":
extra = item._obj.__doc__.strip()
rep.nodeid = extra
return rep
that is close, but it repeats the filename on every line:
$ py.test test_single.py
======================================================================================== test session starts =========================================================================================
platform darwin -- Python 2.7.7 -- py-1.4.26 -- pytest-2.6.4
plugins: greendots, osxnotify, pycharm
collected 2 items
test_single.py
And two plus two is still four .
test_single.py
And one plus one is still two .
====================================================================================== 2 passed in 0.11 seconds ======================================================================================
How can I avoid the lines with test_single.py
in the output, or maybe print it only once?
Looking into the source of py.test and some of its plugins did not help.
I am aware of the pytest-spec plugin, but that uses the function's name as a description. I don't want to write def test_two_plus_two_is_four()
.
To expand on my comment to @michael-wan's answer: to achive something similar to specplugin
put into conftest.py
:
def pytest_itemcollected(item):
par = item.parent.obj
node = item.obj
pref = par.__doc__.strip() if par.__doc__ else par.__class__.__name__
suf = node.__doc__.strip() if node.__doc__ else node.__name__
if pref or suf:
item._nodeid = ' '.join((pref, suf))
and the pytest
output of
class TestSomething:
"""Something"""
def test_ok(self):
"""should be ok"""
pass
will look like
If you omit docstrings class/func names will be used.
这篇关于使用 docstrings 列出 py.test 中的测试的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
