Hi all if it was you who created this org https://github.com/pytest please make Holger an admin if this name was taken by someone who's not related to pytest in any way, then we should make a claim to github to get the rights i guess the org is empty and created Oct 21, 2013 -- Anatoly Bubenkov

Python syntax highlighting when displaying failing code?
by Dinu Gherman Oct. 27, 2014

Oct. 27, 2014

Hi, I just wondered how much people here would appreciate a new feature for py.test which would add Python syntax highlighting to failing code shown before asserts etc.? In the following example below that would mean the three lines I marked on the right side with '<'. If we had this the lines already displayed in red and with a leading 'E' might perhaps need to be displaying in reversed mode and still red to stand out more than before. I've done something similar when using fabric for a while wrapped inside of my own package, so I could write "myfab --source mytask" and see the respective highlighted code that would be executed. To do that I used pygments which I think is not too heavy weight to include in py.test, but Holger's mileage may vary. Just let me know what you think. If this is considered worth the effort, I might ask for some little hints pointing me to the code to touch, because in fact I'm not very familiar with the py.test code and lack the time now to make an in-depth code analysis. Cheers, Dinu PS: $ py.test fib.py ============================= test session starts ============================== platform darwin -- Python 2.7.6 -- py-1.4.26 -- pytest-2.6.4 plugins: timeout, pep8, xdist, cache, cov collected 1 items fib.py F =================================== FAILURES =================================== _____________________________________ test _____________________________________ def test(): < "Test fib(10), should not be 10." < > assert fib(10) == 10 < E assert 55 == 10 E + where 55 = fib(10) fib.py:24: AssertionError =========================== 1 failed in 0.04 seconds ===========================

improve -k/-m exercise / want to help pytest?
by holger krekel Oct. 27, 2014

Oct. 27, 2014

Hi all, is anyone interested in a little exercise that would improve pytest usage? It doesn't require deep pytest knowledge. This is about the "-k" and "-m" selection mini-language, namely expressions like: marker1 and marker2 not marker1 and (marker2 or marker3) and so forth. The thing is that pytest currently uses Python's "eval" with a custom dictionary which means that names such as "marker1" cannot have dots or other punctuation and also other things are not possible like running all tests that don't have "4.3" (coming from a parametrized test) in it: -k 'not 4.3' This would currently select all tests because "4.3" is true. Various people have run into traps like this. So what is needed here are tests and code that, given a set of names and an expression string, determines if the expression is true or not. And everything except "and" and "or" are valid words. To use the latter two words probably need to have some escaping like "\and" or so but that's a bonus task :) Anyone up for this little exercise? Or other comments? best and thanks, holger

pytest-2.6.4: bugfix release
by holger krekel Oct. 24, 2014

Oct. 24, 2014

Hi all, just pushed pytest-2.6.4 to pypi, a small bug fix release. pytest is a popular and mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. This release is drop-in compatible to 2.5.2 and 2.6.X. See below for the changes and see docs at: http://pytest.org Thanks to all who contributed, among them: Bruno Oliveira Floris Bruynooghe Dinu Gherman Anatoly Bubenkoff best, holger krekel, merlinux GmbH 2.6.4 ---------- - Improve assertion failure reporting on iterables, by using ndiff and pprint. - removed outdated japanese docs from source tree. - docs for "pytest_addhooks" hook. Thanks Bruno Oliveira. - updated plugin index docs. Thanks Bruno Oliveira. - fix issue557: with "-k" we only allow the old style "-" for negation at the beginning of strings and even that is deprecated. Use "not" instead. This should allow to pick parametrized tests where "-" appeared in the parameter. - fix issue604: Escape % character in the assertion message. - fix issue620: add explanation in the --genscript target about what the binary blob means. Thanks Dinu Gherman. - fix issue614: fixed pastebin support.

xdist grouping: request for user stories
by holger krekel Oct. 24, 2014

Oct. 24, 2014

Hi all, Currently, pytest-xdist in load-balancing ("-n4") does not support grouping of tests or influencing how tests are distributed to nodes. Bruno Oliveira did a PR that satisfies his company's particular requirements, in that GUI tests must run after all others and pinned to a particular note. (https://bitbucket.org/hpk42/pytest-xdist/pull-request/11/) My question is what needs do you have wrt to test distribution with xdist? I'd like to collect and write down some user stories before we design options/mechanisms and then possibly get to implement them. Your input is much appreciated. best and thanks, holger
