Display information about partial branch coverage

[moi90]

Is your feature request related to a problem? Please describe.
Some lines are yellow (partial), but I don't know which branch was taken and which one still needs testing.

Describe the solution you'd like
I would like to have a tooltip that displays additional coverage information.

Describe alternatives you've considered
Currently, this only is available with other tools.

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.

@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.)
