Stuck with running the test about tau-mocha-course HOT 1 OPEN

Got the solution...

Instead of
var assert = require('assert');

I had added
var assert = require('assert').strict();

I was facing few other problems before and starting looking for solution. Adding .strict() was one of them. Still it didn't work.
Re-installed assert module using npm and tests are running fine now.
It would be helpful if you could also add some videos on the file dependencies needed to run js tests using npm.
I don't know much about JS and package.json was new to me.

FYI,
Test run is fine now...
