100% covered when much is uncovered

[mpenning]

I'm using:

• Python 3.11.2
• coveragepy version 7.4.0
• pytest version 7.4.3
• pytest-cov 4.1.0

I'm trying to get coveragepy to work, but I can't seem to get the coverage portion to see uncovered lines.

Assume I clone this ciscoconfparse2 repo (ref git hash 2feeff184d4dee6a2c3b10ff756e0e1151f2ffd2) and then edit ciscoconfparse2/models_cisco.py. I currently see Coveragepy ==> 100% covered when I run :Coveragepy show, but that's obviously not true. There are loads of uncovered methods in that file.

How do I debug / fix what is wrong?

I don't know what is printing Coveragepy ==> 100% covered, it looks like some kind of vim integration? Can you use the coverage.py command-line tools to reproduce the situation?

[mpenning]

I just

• unloaded every plugin that I had (most were related to ale); I also ran :PlugClean to delete them from disk.
• renamed my ~/.vimrc to ~/.vimrc.orig

I still get that same Coveragepy ==> 100% covered message when I run :Coveragepy show, but I definitely don't show 100% coverage here...

Interestingly :Coveragepy show doesn't highlight any missing coverage lines.

What should I do next to debug this?

It sounds like the vim plugin is buggy. I don't know which plugin it is, but I would contact that project.
