mocha: call a test case synchronously

Question

Is it possible to call a test case synchronously with Mocha? For example, I have the code below:

context('Context of test suite', () => {
  it('test case name', () => {
    //call expect() a few times
  })
})
console.log('foo')

I want to run this, but I want to guarantee that foo will not be printed until AFTER the test case has executed and either passed or failed. it does not return a Promise, nor does context , so I can't do it using then . Is what I want possible?

This test case exists inside the after block.

You can move that console.log into a nested after :

describe('all my tests', () => {

  it('#1', done => setTimeout(done, 500))
  it('#2', done => setTimeout(done, 500))
  it('#3', done => setTimeout(done, 500))

  after(() => {

    context('Context of test suite', () => {

      it('test case name', () => {})

      after(() => {
        console.log('foo');
      });
    })

  });

});

Although I have a hard time understanding why you'd use a setup like this. One issue is that you can't use this setup inside a root-level after (one that's outside of any describe block), and also, after isn't meant for additional tests, it's meant to clean up after tests.

I would probably use something like this:

describe('all my tests', () => {

  it('#1', done => setTimeout(done, 500))
  it('#2', done => setTimeout(done, 500))
  it('#3', done => setTimeout(done, 500))

});

describe('Context of test suite', () => {

  it('test case name', () => {})

  after(() => {
    console.log('foo');
  });
})

Ie just place the suite that has to run last, well, last. You can move that last after outside of the suite and promote it to a root-level hook, if you like.
