Release Notes

nedbat/coveragepy (coverage)

v7.6.8

Compare Source

• 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_.

v7.6.7

Compare Source

• 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.

.. _changes_7-6-6:

v7.6.6

Compare Source

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