8.3.4

pytest 8.3.4 (2024-12-01)

Bug fixes

• #12592: Fixed KeyError{.interpreted-text role="class"} crash when using --import-mode=importlib in a directory layout where a directory contains a child directory with the same name.

• #12818: Assertion rewriting now preserves the source ranges of the original instructions, making it play well with tools that deal with the AST, like executing.

• #12849: ANSI escape codes for colored output now handled correctly in pytest.fail{.interpreted-text role="func"} with [pytrace=False]{.title-ref}.

• #9353: pytest.approx{.interpreted-text role="func"} now uses strict equality when given booleans.

Improved documentation

• #10558: Fix ambiguous docstring of pytest.Config.getoption{.interpreted-text role="func"}.

• #10829: Improve documentation on the current handling of the --basetemp option and its lack of retention functionality (temporary directory location and retention{.interpreted-text role="ref"}).

• #12866: Improved cross-references concerning the recwarn{.interpreted-text role="fixture"} fixture.

• #12966: Clarify filterwarnings{.interpreted-text role="ref"} docs on filter precedence/order when using multiple @pytest.mark.filterwarnings <pytest.mark.filterwarnings ref>{.interpreted-text role="ref"} marks.
