 #### nc_index.js File
 * The `nc_index.js` is a file that runs several NC and NSFS mocha related tests.  
 * Before running NC tests, `nc_coretest` setup will be called, and after the run of all tests, `nc_coretest` teardown will be executed.
+* Tip for developers: if you want to run all the NC tests you can run: `sudo NC_CORETEST=true node ./node_modules/mocha/bin/mocha src/test/unit_tests/nc_index.js` (instead of waiting for the image to build and run them in a container using `make run-nc-tests`). The tests will run according to the list. Please notice that in this file there's a part where the `nc_coretest` setup changed (see comment about `test_nc_with_a_couple_of_forks.js`) and add new test files according to the setup you need, probably in the first part with the default setup.
 
 #### nc_coretest.js File
 * The `nc_coretest.js` is a file that runs setup and teardown before/after NC integration tests run.
