Run test files sequentially?

I have multiple test files. Each file has a before and after functions, doing server startup,shutdown and db cleaning activities.

Structure of a sample test file:

describe('some test:', function() {

    before('reset db; start server', start_server)
    after('close server', close_server)

    // some tests
    describe('#clear_expired_signals:', clear_expired_signals)
    describe('#delete_signal ', delete_signal)
}

I am getting EADDRINUSE exception most of the times when these files are executed together because the server is being started in the same port during each before call.

Is it possible to force mochajs to execute single file at a time ( file order is not a concern) ?

Edit:

before function sample

  function start_server(done) {   
    intialize_server.start().then(function(options) {

     seneca = options.seneca;
     seneca.client({
       host: 'localhost',
       port:options.port,
     }); 
     done();
  }

}



function intialize_server(){
return new Promise(function (resolve, reject) {
    seneca.ready(function () {

      seneca.listen({
        host: 'localhost',
        port: custom_port,
      });

      resolve({
        seneca: seneca,
        port: custom_port
      });
      // console.log('test server listening')
    });
  });
 }

after function sample

 function close_server(done) {
   console.log('closing seneca instance');
  seneca.close(done);
  }

I got around this problem. Instead of running before and after for each test file, I have added ROOT-LEVEL HOOKS as given in the documentation

ROOT-LEVEL HOOKS

You may also pick any file and add “root”-level hooks. For example, add beforeEach() outside of all describe() blocks. This will cause the callback to beforeEach() to run before any test case, regardless of the file it lives in (this is because Mocha has an implied describe() block, called the “root suite”).
