No longer getting console output after updating from v8 to v9

[GeorgDangl]

A few days ago, we've updated an Electron / Angular application from Mocha 8.2.1 to 9.0.3. Since then, there's no longer any console output when running tests.

That's a bit strange, since everything works, xml test results are written and even directly calling console.log() in the tests works fine. Just, nothing from Mocha...

I'm a bit at a loss here, since I didn't see anything like this in the changelog or mentioned anywhere. It's very likely just a configuration issue on my side, but there's not a lot of actual configuration happening. Supplying --dry-run to the CLI just prints out nothing.

It's almost as if there were some silent flag enabled, but I didn't find an option for that in the docs. An initial scan of the files in node_modules/mocha also didn't reveal anything...

Do you have any idea what's happening here?

After digging a bit deeper, I actually now found the issue. Its the mocha-junit-reporter` plugin. Disabling that produces the console output again.

However, that version hasn't changed, only the mocha package was updated. Do you know if there's any workaround for this?

@GeorgDangl There is an open issue mocha-junit-reporter/issues/135 dated Aug/2020.
So this doesn't seem to be an issue related to recent Mocha releases, but to mocha-junit-reporter itself.

@juergba, thank you very much! I've been able to resolve it by simply using mocha-multi-reporters with both the spec and the mocha-junit-reporter reporter.
