I often found myself thinking “Wait? What’s the execution order of before, beforeEach, after, afterEach in Mocha?”, so I wrote this article.

Execution order is before, beforeEach, afterEach, after

To write the conclusion first:

1. before
2. beforeEach
3. test
4. afterEach
5. after

They are executed in this order.

Mocha Sample Code

Below is sample mocha code to check the execution order of before, beforeEach, afterEach, after.

describe('before test', function() {
  before(function() {
    console.log('before');
  });

  beforeEach(function() {
    console.log('beforeEach');
  });

  after(function() {
    console.log('after');
  });

  afterEach(function() {
    console.log('afterEach');
  });

  it('test', function() {
    console.log('test');
  });
});

I want to write test code with a good understanding of what processes are called where.

That’s all from the Gemba.
