Detailed Description

Pytest is a popular Python framework for writing tests. The 8th major release brings various improvements. The most notable enhancements are:

The diffs that pytest prints when an assertion fails were improved.
Added the new verbosity_assertions configuration option for fine-grained control of failed assertions verbosity.
Additional support for exception groups and __notes__
custom directory collectors
“new-style” hook wrappers are now used internally

Breaking changes:

PytestRemovedIn8Warning deprecation warnings are now errors by default
Several breaking changes to pytest’s collection phase, particularly around how filesystem directories and Python packages are collected, fixing deficiencies and allowing for cleanups and improvements to pytest’s internals.
Sanitized the handling of the default parameter when defining configuration options
pytest’s setup.py file is removed
warns() now re-emits unmatched warnings when the context closes – previously it would consume all warnings, hiding those that were not matched by the function
The internal FixtureManager.getfixtureclosure method has changed. Plugins which use this method or which subclass FixtureManager and overwrite that method will need to adapt to the change.

Benefit to Fedora

Fedora offers cutting-edge technologies for Python and pytest is one of the most important Python packages. By doing this update we bring users the latest features that pytest offers and also we enable Fedora 41 to receive future updates as well.

Scope

Proposal owners: update pytest to 8.x.x, provide help

Other developers: report problems to the upstream and backport patch to the affected packages. The impact can be tested using copr repository where Pytest 8.x.x has been built. Alternatively you can open a PR to distgit and see the result in CORP - https://copr.fedorainfracloud.org/coprs/thrnciar/pytest/builds/?dirname=pytest:pr:<your PR number>

Release engineering: #Releng issue number

Policies and guidelines: N/A (not needed for this Change)

Trademark approval: N/A (not needed for this Change)

Alignment with Objectives:

Upgrade/compatibility impact

There is a clean upgrade path from current version to pytest 8.x.x. Fedora users using RPM-packaged Pytest will use pytest 8.x.x by default.

How To Test

Find the package you want to update in this copr repository and check the build logs to determine the fail cause.
Work with the upstream to resolve the issue.
When updating the package, you can test it using the same copr repository where the latest version of pytest has been built.
Let us know if something doesn't work as it should.

User Experience

Regular distro users shouldn't notice any change in pytest behaviour, except for packages using removed functions. Such packages will fail and should be fixed by their maintainers.

Contingency Plan

Contingency mechanism: (What to do? Who will do it?) N/A (not a System Wide Change)
Contingency deadline: N/A (not a System Wide Change)
Blocks release? N/A (not a System Wide Change)
