How to detect all tests (in multiple files) finished

I would like to drop database after all tests in all files ran. Is there a hook for it in Mocha?

after() hook can be applied only within 1 file only.

There is a root level hook in mocha. For your case, you can create a new file and specify drop database command in after function. That's it!

// init-test.js

after(function() {
  // drop database
});

You don't need to move any test in other test file for this solution.

I'm using process.on('exit'). It works when running only one file as well as when running tests from package.json.

database.mocha-base.js:

db.connect()

process.on('exit', async () => {
  console.log('All tests finished. Droping database')
  db.dropDatabase(dbName)
  db.disconnect()
})

module.exports = {
  applyHooks() {
     before(async () => {
        // truncate tables
     })
  }
}

I'm including database.mocha-base.js in all tests that need database access: 

const dbMochaBase = require('./path/to/database.mocha-base.js')

describe('Tests', () => {
   dbMochaBase.applyHooks()

   ...
})

Create a parent file that includes/requires all other tests, then use after within that file:

describe('User', () => {
  require('../user/user.spec.js')
})

describe('Post', () => {
  require('../post/post.spec.js')
})

describe('Tag', () => {
  require('../tag/tag.spec.js')
})

describe('Routes', () => {
  require('./routes.spec.js')
})

after(() => {
  // drop database
})
