should allow the send shorthand

with callback in the method call
request.get(`${uri}/login`, (err, res) => {

  done();
});
with data in the method call
request.post(`${uri}/echo`, { foo: 'bar' }).end((err, res) => {

  .then((res) => res.status)
  .then()

  });
called only once with a promise
if (typeof Promise === 'undefined') {

  results.forEach((item) => {
    assert.equal(
