Split mocha API test in multiple files

I'm building some API tests for the product I'm building. One of the test looks like this:

GET FILTERS
  ✓ should be restricted (45ms)
  it should get the filters
    ✓ should return 200
    ✓ should return an object
    ✓ should close db connections
GET USERS COUNT
  ✓ should be restricted
  ✓ should throw error when payload is not correct
  it should get the user count
    ✓ should return 200
    ✓ should return an object
    ✓ should close db connections
GET USERS FILE
  ✓ should be restricted
  ✓ should throw error when no queryId is specified
  it should retrieve the file
    ✓ should return 200
    ✓ should download an excel file
    ✓ should close db connections
UPLOAD PROMOTION IMAGE
  ✓ should throw error when no file is specified
  it should save the file
    ✓ should return 200
    ✓ should have named the file with the title of the promotion
    ✓ should have uploaded the file to S3 (355ms)
    ✓ should close db connections
CREATE PROMOTION
  it should save the promotion
    ✓ should return 200
    ✓ should return a correct response
    ✓ should close db connections
GET PROMOTIONS
  ✓ should be restricted
  it should get the promotions
    ✓ should return 200
    ✓ should be an array of promotions
    ✓ should contain the previously created promotion
UPDATE PROMOTION
  it should update the promotion
    ✓ should return 200
    ✓ should return a correct response
    ✓ should close db connections
PUT PROMOTION IN BIN
  it should put the promotion in the bin
    ✓ should return 200
    ✓ should return a correct response
    ✓ should close db connections
GET ARCHIVED PROMOTIONS
  ✓ should be restricted
  it should get the promotions
    ✓ should return 200
    ✓ should be an array of promotions
    ✓ should be an array of archived promotions
    ✓ should contain the previously archived promotion
DELETE PROMOTION
  it should delete the promotion
    ✓ should return 200
    ✓ should return a correct response
    ✓ should have deleted the file from S3 (563ms)
    ✓ should close db connections

As you can see I've tried to put everything regarding promotions in a single test suite so that I can have a sort of workflow to test what the user will do exactly on the platform.

In this example I create a random generate promotion and then use the id of that promotion to read it, update it, archive it and then finally delete it. Every step is connected and I need to have return values for each suit (i.e: The ID of the inserted promotion, or the filters...)

At this moment my promotions.test.js file is 625 and, since I have not finished yet, I expect it to grow a lot in the next days.

Is there a way to split multiple test suits in different files but in a way that each test/file is able to return, as soon as it finishes, a value that I can pass to the next step ?
