Mocha, running tests serially with inner test loop

I'm probabbly doing a bad thing here, because I'm having dependencies between tests, but I'd rather call it initialization.

Here's what I have:

describe('e2e', function () {
    this.timeout(30000);
    let domainWork = [];

    it('should prepare material', function (done) {
        glob("test/e2e/*", function (err, domains) {

            Promise.all(domains.map(function (domain) {
                console.log('new domain ' + domain);

                let rqUrl = extractDomainUrl(domain);

                constructPairs(domain)
                    .then(function (pairs) {
                        let work = {
                            domain: domain,
                            work: pairs,
                            rqUrl: rqUrl
                        };

                        domainWork.push(work);
                        Promise.resolve();
                    })

            }))
                .then(function () {
                    done();
                });
        });
    });

    it('should test domains', async function () {
        return Promise.all(domainWork.map(function (domain) {

            it('domain ' + domain.url, async function () {

                return Promise.all(domain.work.map(function (casse) {
                    it('testCase  ' + casse.caseNum, async function () {

                        chai.request(server)
                            .post(rqUrl)
                            .send(casse.req)
                            .end(async (err, res) => {
                                expect(err).to.be.null;

                                let comparison = compareJSON(casse.res, res.body);
                                if (comparison)
                                    return Promise.resolve();
                                else
                                    return Promise.reject();
                            });
                    })
                }))
            })
        }))
    });

});

So what I need to do is to initialize an array domainWork and then run tests with for this data in the loop. I have read somewher in this forum, that you can run tests in the loop. So I have 'prepare material'-it I have second one 'should test domains'-it which should serve as describing for upcoming operations and encapsulate loop through "test domains" (domainWork array).

Now, what happens when I run this, is that first test initializes 'domainWork' array. Then it gets to the second test, but the inner most test/it is never being executed.

What I need to do in odrer to execute the inner test? Or what would be the better solution to rewrite this?

Thanks!
