I installed mocha with -g parameter, though it's not been working for me with other modules: I always had to link them, so that i can require them.

It looks like you're not starting mocha properly. You shouldn't have that require of 'mocha' in there, and you need to be starting this using 'mocha' on the command line.

The thing with mocha is that it doesn't just require your test module. It loads it into a special context, which is where global functions like 'describe' come from. In your case, 'describe' is not defined almost certainly because mocha was not started properly.

This is my code:

var Mocha = require('mocha');

var assert = require("assert")

describe('Array', function(){

  describe('#indexOf()', function(){

    it('should return -1 when the value is not present', function(){

      assert.equal(-1, [1,2,3].indexOf(5));

      assert.equal(-1, [1,2,3].indexOf(0));

    })

  })

})

Thank you, Martin. I solved my problems, but there's another question: everything seems to work, test are running, but when i try to implement http.get logic - it doesn't work. the code

var http = require('http');

http.get("http://www.google.com/index.html", function(res) {

 console.log("Got response: " + res.statusCode);

}).on('error', function(e) {

 console.log("Got error: " + e.message);

});

when I run "mocha" in console just writes "0 tests complete (0 ms)", without logging anything.

you need a describe in it to mark it as a test. mocha doesn't simply 'require' your test files
