Release Notes

nedbat/coveragepy

v5.5

Compare Source

• coverage combine has a new option, --keep to keep the original data
  files after combining them. The default is still to delete the files after
  they have been combined. This was requested in issue 1108_ and implemented
  in pull request 1110_. Thanks, Éric Larivière.

• When reporting missing branches in coverage report, branches aren't
  reported that jump to missing lines. This adds to the long-standing behavior
  of not reporting branches from missing lines. Now branches are only reported
  if both the source and destination lines are executed. Closes both issue 1065_ and issue 955_.

• Minor improvements to the HTML report:

  • The state of the line visibility selector buttons is saved in local storage
    so you don't have to fiddle with them so often, fixing issue 1123_.

  • It has a little more room for line numbers so that 4-digit numbers work
    well, fixing issue 1124_.

• Improved the error message when combining line and branch data, so that users
  will be more likely to understand what's happening, closing issue 803_.
