I am building an app using the MEAN stack and Webdriver for testing.

At the moment I am cleaning the database between tests by using Mocha's beforeEach and afterEach hooks, e.g.:

describe('Links', function() {
  // drop DB collections

  beforeEach(function(done){
    //create database objects
  });

  afterEach(function(done){
    // drop DB collections
  });
});

Is there a way of setting up wdio.conf.js for this to happen before and after each of my tests automatically? The config's before: and after: function() {} run as a beforeAll / afterAll rather than for each test.
