it('should count assertions', (done) => {
  const ok = counter(5, done);
  // or without done
  const ok = counter(5); // then return ok.promise

  ok()

  // can take an error

  ok(async () => {
    throw new Error('not ok') // calls done(error)
  })

  const callMe = () => {
    // the function passes results from previous calls
    ok(...previousArgs => {
      assert.equal(previousArgs[0], 'ok')
