Mocha before callbacks

TL’DR

• All before block run first in top down order
• Then all beforeEach blocks run in top down order
• Then all the afterEach blocks run in top down order
• Finally all the after blocks run in top down order

Example

This is from before.js gist:

describe('mocha before hooks', function () {
  before(() => console.log('*** top-level before()'));
  beforeEach(() => console.log('*** top-level beforeEach()'));
  describe('nesting', function () {
    before(() => console.log('*** nested before()'));
    beforeEach(() => console.log('*** nested beforeEach()'));
    it('is a nested spec', () => true);
  });
});

  mocha before hooks
*** top-level before()
    nesting
*** nested before()
*** top-level beforeEach()
*** nested beforeEach()
      ✓ is a nested spec
