Rspec expect keeps throwing a TypeError: nil is not a symbol

Question

So I have this test in my app:

expect{
  post :create, :name=> 'abc'
}.to change(Event.count).from(0).to(1)

and it keeps throwing he this error:

TypeError: nil is not a symbol

Would anyone know why?

Answer 1

Found out the issue. Should be using {} instead of (). Should be this instead:

expect{
  post :create, :name=> 'abc'
}.to change{Event.count}.from(0).to(1)

Answer 2

You can also do it as below:

expect{
  post :create, :name=> 'abc'
}.to change(Event, :count).from(0).to(1)
