7.7.0

Version 7.7.0 — 2025-03-16

• The Coverage object has a new method, Coverage.branch_stats() for getting simple branch information for a module. Closes issue 1888.
• The Coverage constructor now has a plugins parameter for passing in plugin objects directly, thanks to Alex Gaynor.
• Many constant tests in if statements are now recognized as being optimized away. For example, previously if 13: would have been considered a branch with 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.

7.6.12

Version 7.6.12 — 2025-02-11

• Fix: some aarch64 distributions were missing (issue 1927). These are now building reliably.

7.6.11

Version 7.6.11 — 2025-02-08

• Fix: a memory leak in CTracer has been fixed. The details are in issue 1924 and pytest-dev 676. This should reduce the memory footprint for everyone even if it hadn’t caused a problem before.
• We now ship a py3-none-any.whl wheel file. Thanks, Russell Keith-Magee.

7.6.10

Version 7.6.10 — 2024-12-26

• Fix: some descriptions of missing branches in HTML and LCOV reports were incorrect when multi-line statements were involved (issue 1874 and issue 1875). These are now fixed.
• Fix: Python 3.14 defers evaluation of annotations by moving them into separate code objects. That code is rarely executed, so coverage.py would mark them as missing, as reported in issue 1908. Now they are ignored 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’t understand the problem or the solution, but git bisect helped find it, and now it’s fixed.
• Docs: re-wrote the Measuring subprocesses page to put multiprocessing first and to highlight the correct use of https://docs.python.org/3/library/multiprocessing.html#multiprocessing.pool.Pool.

7.6.9

Version 7.6.9 — 2024-12-06

• Fix: Tomas Uribe fixed a performance problem in the XML report. Large code bases should produce XML reports much faster now.

7.6.8

Version 7.6.8 — 2024-11-23

• 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.

7.6.7

Version 7.6.7 — 2024-11-15

• Fix: ugh, the other assert from 7.6.5 can also be encountered in the wild, so it’s been restored to a conditional. Sorry for the churn.

7.6.6

Version 7.6.6 — 2024-11-15

• One of the new asserts from 7.6.5 caused problems in real projects, as reported in issue 1891. The assert has been removed.

7.6.5

Version 7.6.5 — 2024-11-14

• Fix: fine-tuned the exact Python version (3.12.6) when exiting from with statements changed how they traced. This affected whether people saw the fix for issue 1880.
• Fix: isolate our code more from mocking in the os module that in rare cases can cause bizarre behavior.
• Refactor: some code unreachable code paths in parser.py were changed to asserts. If you encounter any of these, please let me know!
