Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

Timeout 추가로 해결

https://mochajs.org/#timeouts

describe('a suite of tests', function() {
  this.timeout(500);

  it('should take less than 500ms', function(done){
    setTimeout(done, 300);
  });

  it('should take less than 500ms as well', function(done){
    setTimeout(done, 250);
  });
})

추가로 참고할점은

ArrowFunction 사용시 this를 알아먹지 못한다.

https://mochajs.org/#arrow-functions

describe('my suite', () => {
  it('my test', () => {
    // should set the timeout of this test to 1000 ms; instead will fail
    this.timeout(1000);
    assert.ok(true);
  });
});

테스트 할때는 그냥 ArrowFunction 버리고 기존 function으로 작성하는게 좋을듯하다.
