Add "--deselect" command line option #3201

uSpike · 2018-02-09T23:50:29Z

I implemented this as a new CLI option --deselect since it does have different functionality than --ignore, which completely ignores the file.

The code matches any nodeid that startswith() any --deselect flag.

Create a new changelog file in the changelog folder, with a name like <ISSUE NUMBER>.<TYPE>.rst. See changelog/README.rst for details.
Target the features branch for new features and removals/deprecations.
Include documentation when adding new features.
Include new tests or update existing tests when applicable.
Add yourself to AUTHORS in alphabetical order

+    result = testdir.runpytest("--deselect=test_a.py::test_a2[1]")
+    assert result.ret == 0
+    result.stdout.fnmatch_lines(["*11 passed, 1 deselected*"])


This should be 10 passed, 1 deselected right?

Also I think it would be better to use -v and deselect two tests and ensure they are not being run. You can parametrize test_a2 using a smaller value (say 3) so the test remains tidy and small.

+            if colitem.nodeid.startswith(opt):
+                deselected.append(colitem)


I believe this needs a break after deselected.append(colitem)

startswith can take a tuple which can be used as a much better selector

instead of a loop and the for else hack it could simply use colitem.nodeid.startswith(deselect_prefixes)

i presume the break was not added due to the expectation of the prefixes being distinct/non-overlapping

Oh cool, thanks I didnt realize str.startswith() takes a tuple. That's great.

i propose a metavar of nodeid_prefix

@RonnyPfannschmidt @nicoddemus I've implemented your suggestions, thanks much for the feedback.

well done, please also move the call to tuple to the place where deselect_prefixes is declared

Fixes pytest-dev#3198

blueyed · 2018-02-16T14:35:26Z

In #3198 you said:

I propose to accept test ids with --ignore:

This would not need a new option then.

btw: I've also thought about this being something negating -k (e.g. -K) - but that would be a different feature (since it uses different logic / evaluation).

uSpike · 2018-02-16T15:25:35Z

@blueyed yes I had originally thought that I could add to --ignore but the functionality of --ignore ended up being fundamentally different than what I needed. I will update #3198.

nicoddemus · 2018-02-16T22:50:40Z

Thanks @uSpike!

blueyed · 2018-02-19T22:23:06Z

I still think that it is confusing to have --ignore and --deselect now, and that support for foo.py::X should get added to --ignore instead.

--deselect requires the filename as a prefix already, and therefore is only a specialized version of --ignore, isn't it?

twmr · 2018-02-20T08:28:47Z

I guess that it makes sense to mentioned in the docs what the differences between --ignore and --deselect are

uSpike · 2018-02-20T16:39:22Z

--ignore is not exactly the same as --deselect. Paths that are excluded by --ignore are not reported anywhere via pytest_deselected or on the CLI. Items that are deselected by --deselect are passed to pytest_deselected and reported as so on the CLI.

I'm not sure if it's more or less confusing with --ignore if things that look like paths are not considered for collection at all, and things that look like node ids are deselected. It's a simple implementation and I'd be happy to submit another PR if there's interest.

uSpike · 2018-02-20T16:45:55Z

I have a working implementation here: uSpike@8b98792

blueyed · 2020-02-19T20:27:35Z

@uSpike
Thanks for following up with merging this with --ignore, and sorry for having missed it previously.
Would you like to follow up on that? (given that there just was confusion with --deselect not handling paths)
