Release Notes

nedbat/coveragepy (coverage)

v7.7.0

• The Coverage object has a new method, :meth:.Coverage.branch_stats for
  getting simple branch information for a module. Closes issue 1888_.

• The :class:Coverage constructor<.Coverage> now has a plugins parameter
  for 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 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.
