Display information about partial branch coverage about vscode-coverage-gutters

@moi90 Thanks for the example, it definitely looks doable and there is other work that is similar to this (adding ui elements similar to codelens) that could be done in parallel with this.

Cool, I'm looking forward to it! (But take your time, this extension is already a great help as it is.)

Thanks for the ticket @moi90!

Do you have an example from another tool you can share?

Currently, the highlighting is the whole line or none of the line, but I wonder if it could be more "partial" as well. Meaning, if the line has a partial branch (like you alluded to) the coverage highlight would only go as far as the code had traversed.

Definitely something to investigate or an option as well (it might be easier to implement than other popover gui elements as I am not familiar with that area of the vscode extension api).

pytest-coverage's html output displays some additional information:

The corresponding xml is:

<line number="40" hits="1" branch="true" condition-coverage="50% (1/2)" missing-branches="41"/>

I find the "40 ↛ 41" especially useful. Seeing the condition-coverage would be useful as well.

But I would understand if these (mostly cosmetical) improvements do not justify the effort.
