You can just run:

mocha path-to-dir/**/*.js --timeout 15000

The two ** are the same as --recursive

There are quite a few options here depending on exactly what you need, imho straight execution based on path gets a bit cumbersome.

Directory based segregation of tests

Everything in a directory - mocha test/<folderPath>/*.js

Everything including sub-directories - mocha test/<folderPath>/**/*.js

Pattern matching for suites ( or tests )

Suite - mocha --grep <suiteName>

Pattern Match - mocha --grep <pattern>

Negative Pattern matching for suites ( or tests )

Suite - mocha --grep <suiteName> --invert

Pattern Match - mocha --grep <pattern> --invert

Tagging

You can also execute test based on tags within the it() portion of the test.

Tagging uses the --grep feature which also allows for negative tag matching.
