Group suites over multiple files

[marcojahn]

When splitting my tests accross multiple files I got them grouped for each file.

// file1.js
describe('test 1 - file 1', function () {
    // more testcode here
});

// file2.js
describe('test 1 - file 2', function () {
    // more testcode here
});

The output is as expected

test 1 - file 1
    (tests listed here)
test 1 - file 2
    (tests listed here)

But I wonder if it is possible to group these tests by defining an additional "shared" describe

// file1.js
describe('grouped', function () {
    describe('test 1 - file 1', function () {
        // more testcode here
    });
});

// file2.js
describe('grouped', function () {
    describe('test 1 - file 2', function () {
        // more testcode here
    });
});

The expected output would be

grouped
    test 1 - file 1
        (tests listed here)
    test 1 - file 2
        (tests listed here)

This is how I currently achieve the desired output, but I am not sure if it just a workaround or how it should be done.

export default function () {
    describe('test 1 - file 1', function () {
        // more testcode here
    });
}

import Test1 from './test1.js';

describe('grouped', function () {
    Test1();
});

Here's the same solution, but with different syntax:

one.js

function test1 () {
  describe('test 1 - file 1', function () {
    it('should be true', function () {
      expect(true).to.be.true
    })
  })
}
module.exports = {
  test1:test1
}

(do that ^ for each file of tests)

and this to use them in a group:
grouped.js

const one = require('./one.js')
const two = require('./two.js')
describe('grouped', function () {
  one.test1()
  two.test1()
})

Hope that helps

1. If you do that, you can no longer run this one particular file - you can only run it as a part of the suite.
2. That's not ideal, since adding new test suits, requires editing the "joiner module", and can cause for example conflicts when merging multiple codes.
