this.title prints out suite title, not test title

Hi,

I'm trying to access title of the test case I'm currently with by running:
this.title
Unfortunately, I'm getting only Test Suite title.
Here is an example:

const forEach = require('mocha-each');
describe("TEMPORARY SUITE.", function() {

    forEach( [0,1]).it("Test #%s", () => {
        console.log(this.title);
    });
});

Output:

  TEMPORARY SUITE.
TEMPORARY SUITE.
    ✓ Test #0
TEMPORARY SUITE.
    ✓ Test #1

Okay, I found the root cause.
When we use arrow functions, not function statements in it() , the scope of this is very different.
Will mocha-each be supporting full functionality with arrow functions? Or is it completely under control of mochajs devs?

The reference of this in mocha-each's it() is same as Mocha's it() so you can use same helper methods like this.timeout in mocha-each unless you use arrow functions.
But it seems Mocha doesn't set this.title inside of it() blocks.

describe('suite title', function() {
  console.log(this.title);  // 'suite title'

  it('test case title', function() {
    console.log(this.title);  // undefined
  });
});

However, we can access test case titles (and some other meta data) in beforeEach() and afterEach() instead of it() (mochajs/mocha#794).

describe('suite title', function() {
  beforeEach(function() {
    console.log(this.currentTest.title);
  });

  it('normal test', () => {});

  forEach([0, 1]).it('test #%s', () => {});
});

Output:

normal test
    ✓ normal test
test #0
    ✓ test #0
test #1
    ✓ test #1

I think this meets your requirement :)

Is there any way that we can get title of mocha tests in the same test.

describe("Login sample test",function()
{
console.log(this.title);
beforeEach( function()
{
console.log("beforeEach");
this.currentTest.title; //fails here, currentTest undefined
})

afterEach( function()
{
    console.log("afterEach");
})

before( function()
{
    console.log("before");
})

after( function()
{
    console.log("after");
})

it("Login to Application",function(){
    console.log("test");
    console.log(this.title);
    console.log(this.currentTest)
})
it("Login to Application2",function(){
    console.log("test");
    console.log(this.title); //fails here, title
    console.log(this.currentTest) //fails here, currentTest undefined
})

})
