Use spy

Spies are an alternate type of test double that support this pattern by allowing you to expect that a message has been received after the fact, using have_received.

RSpec.describe "have_received" do
  it "passes when the message has been received" do
 invitation = spy('invitation')

Problem

How to test complex controller method with chained method ?

Example

  
  def update
    # ...
 user.propositions.call

pierrax

Use pluck instead of map

Celebrity.all.map(&:id)

=> Time: 3.925s

Celebrity.select(:id).map(&:id)

=> Time: 0.098s

=== Operator

How it works ?

x === y checks if y belongs to x group.

  String === "hello" # true
  String === 1 # false
  
 (1..10) === 3 # true
