How to set session in phoenix controller tests

If you are reading this, you probably tried to write code like this

test "testing session" do
  build_conn()
  |> put_session(:user_id, 234)
  |> get("/")
  ...
  end

And got this exception:

Put your UIViewcontroller on a diet

Put your UIViewcontroller on a diet

I hate to say it but our view controllers have gotten fat, and it's our fault! We feed them protocol after protocol, business rule after business rule. They don't know any better and they just gobble them all up...

This will be a 3 part "Tune up your table view" series in which we will take an old fat view controller, slim it down with some refactoring, freshen it up with some MVVM and then make it fly with some better asynchronous operation management!

In part 1 using refactoring and a couple of Interface Builder tricks hopefully I can provide some motivation to start your journey towards getting your view controllers back in fighting shape!

The current state of things...

UITableViews are pretty integral to most iOS apps so I'm going to use it as an example of how to change a 'fat' view controller into a 'slim' one.

Make your UIViewController Awesynchronous!

Make your UIViewController Awesynchronous!

Welcome back for the conclusion of this 3 part series! In part 1 we learnt how to slim down our view controllers to a manageable size. In part 2 we learnt how to strip out all the non-ui related logic. This time we are going to focus solely on the UITableView and how we can properly handle multiple asynchronous operations in its cells for maximum performance!

As always we will be starting with our project from last time.

What's making our table's scrolling so bad?

Our current implementation is very bad... our UITableViewCells are performing an expensive operation, and on the main thread no less!

The following code is currently in the setup method of our cell:
