Mocha docs: Explain differences between `runTests` and `mocha`

[atjn]

Under "Writing Tests / HTML Tests", you explain that to use Mocha, one must import the runTests function and run the tests in that.

Under "Test Frameworks / Mocha / Writing HTML tests", you explain that to use Mocha, one must import the mocha object along with sessionFinished and sessionFailed and use those to run the tests.

So which one should I use? And what are the differences? There is no documentation explaining any of that.

I agree it's not clear from our docs, also not clear why seemingly the same functions are imported from 2 different packages in 2 different examples.

I'm not writing HTML tests like this in my daily job, so not sure how to help, hope that some other maintainers can have a look.

Meanwhile I'd recommend to go with runTests, as it seems like it's the most mimimal setup possible.
I assume other setups give you more flexibility, so you'll know when you need to use them.
