Nodejs/Mocha: before all hook timeout

Currently, I'm creating API tests. Before all the tests, the database is refreshed by dropping and creating the tables.

    before(function(done) {
       database.dropTables(function(){
           database.createTables(function () {
              console.log('database cleaned');
              done();
           });
       });
    })

When I try to run my tests, I get a timeout at this before hook, although i'm calling the done function.
