Code Coverage Reporting

[benkraus]

So, one thing our company likes to see is code coverage numbers. I'd love to see this plugin enable support for this.

Mainly, I'd like to see two things:

• Code coverage indicators by the line numbers. I'd love to see an indicator that shows if that line was touched by tests, and perhaps how many times, similar to how Xcode does it.
• Reporting when running the tests - what percentage you are at when it comes to code coverage numbers.

Thoughts on the matter?

I'd also love to help build this, though I'm a noob at VS Code extensions.

To do useful code coverage, we would need to run the full test suite - feasible, but usually a non-trivial amount of time. That's what makes this hard to do inside this extensions.

I thought about this a bit before - I think this is generally covered by other extensions, notably this one

Ideally vscode-jest wouldn't provide code coverage stats, because it's nearly always running the watcher for just one file. That said, you can test it out by changing the jest.pathToJest to include the CLI params for outputting code coverage files to be picked up by other extensions. Could work well with something to show coverage, in which case we should consider an option to toggle it.

And is it possible to integrate nojvek/vscode-coverage as part of vscode-jest ? So out of the box you got a better experience. Perhaps with a feature flag to be able to turn it off?

Partial support with #137 It shows uncovered lines in a file and at the top of a file it will show file level coverage.
