v7.8.0
Compare Source
Added a new
source_dirs
setting for symmetry with the existingsource_pkgs
setting. It's preferable to the existingsource
setting,because you'll get a clear error when directories don't exist. Fixes
issue 1942
. Thanks,Jeremy Fleischman <pull 1943_>
.Fix: the PYTHONSAFEPATH environment variable new in Python 3.11 is properly
supported, closing
issue 1696
. Thanks,Philipp A. <pull 1700_>
. Thisworks properly except for a detail when using the
coverage
command onWindows. There you can use
python -m coverage
instead if you need exactemulation.

The Coverage object has a new method, :meth:
.Coverage.branch_stats
forgetting simple branch information for a module. Closes
issue 1888
_.The :class:
Coverage constructor<.Coverage>
now has aplugins
parameterfor passing in plugin objects directly, thanks to
Alex Gaynor <pull 1919_>
_.Many constant tests in if statements are now recognized as being optimized
away. For example, previously
if 13:
would have been considered a branchwith one path not taken. Now it is understood as always true and no coverage
is missing.
The experimental sys.monitoring support now works for branch coverage if you
are using Python 3.14.0 alpha 6 or newer. This should reduce the overhead
coverage.py imposes on your test suite. Set the environment variable
COVERAGE_CORE=sysmon
to try it out.Confirmed support for PyPy 3.11. Thanks Michał Górny.

Fix: a memory leak in CTracer has been fixed. The details are in

_ andpytest-dev 676
_. This should reduce the memory footprint foreveryone even if it hadn't caused a problem before.

Fix: some descriptions of missing branches in HTML and LCOV reports were
incorrect when multi-line statements were involved (
issue 1874
_ andissue 1875
_). These are now fixed.Fix: Python 3.14
defers evaluation of annotations <pep649_>
_ by moving theminto separate code objects. That code is rarely executed, so coverage.py
would mark them as missing, as reported in
issue 1908
_. Now they areignored by coverage automatically.
Fixed an obscure and mysterious problem on PyPy 3.10 seemingly involving
mocks, imports, and trace functions:
issue 1902
_. To be honest, I don'tunderstand the problem or the solution, but
git bisect
helped find it,and now it's fixed.
Docs: re-wrote the :ref:
subprocess
page to put multiprocessing first and tohighlight the correct use of :class:
multiprocessing.Pool <python:multiprocessing.pool.Pool>

Fix: the LCOV report code assumed that a branch line that took no branches
meant that the entire line was unexecuted. This isn't true in a few cases:
the line might always raise an exception, or might have been optimized away.
Fixes
issue 1896
_.Fix: similarly, the HTML report will now explain that a line that jumps to
none of its expected destinations must have always raised an exception.
Previously, it would say something nonsensical like, "line 4 didn't jump to
line 5 because line 4 was never true, and it didn't jump to line 7 because
line 4 was always true." This was also shown in
issue 1896

Fix: a final wildcard match/case clause assigning to a name (
case _ as value
) was incorrectly marked as a missing branch. This is now fixed,closing
issue 1860
_.Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution. Closes

_.Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation. This is now fixed, closing

.Fix: the LCOV report now has correct line numbers (fixing

issue 1850
). Thereare other changes to lcov also, including a new configuration option
:ref:
line_checksums <config_lcov_line_checksums>

checksums set it to true. All this work is thanks to Zack Weinberg
