How to use "Preview Coverage Report" function?

[olalonde]

Trying to use the Preview Coverage Report function but can't figure out what I'm doing wrong. It's asking me to choose a coverage report to preview but there is no drop down and writing a file path or selecting a file from the file explorer results in a popup that says "Did not choose a file!".

@olalonde Thanks for the discussion!
Are you able to try out the preview feature from the examples project? That should produce a GUI like the one below.

The preview feature is fairly basic and just looks for index.html files within the coverage folders.
You can modify where this location is via the settings though.

        "coverage-gutters.coverageReportFileName": {
          "type": "string",
          "scope": "resource",
          "default": "coverage/**/index.html",
          "description": "default coverage report file names(can be glob style) to look for when using the preview command"
        },
