Our 9 o’clock standup went relatively smoothly and we quickly went back to our desks and resumed the database exercises. I have come to realise how easy it was to make typos which could have a detrimental impact on your result. For example, I spent long time on Sunday working out why my computer test kept failing.

My test was:

describe Computer do

  let(:options) { double :options }

  it 'can choose a random option' do
    allow(options).to receive(choices).and_return([:rock, :paper])
    computer = Computer.new(options)
    expect(computer.options).to include(computer.choose)
  end

end

And my error message was:

Failures:

1) Computer can choose a random option
Failure/Error: allow(options).to receive(choices).and_return([:rock, :paper])
NameError:
undefined local variable or method `choices' for #<RSpec::ExampleGroups::Computer:0x007fd2ac23ad80>

I was going over and over again why my choices method wasn’t working. Have you spotted why?

The reason was I had missed to put a colon : i.e. :choices. Yeah…

And today, a long long time was spent figuring out why one of my feature tests was failing. The reason you may ask? I was getting an error 500 which meant that there was something wrong with my database… well there was something wrong with my spelling - I was calling Link.urls to view all the urls in my database table but…. urls was not the correct spelling… it was url.

So from now on whenever I receive an error message, the first thing I check is my spelling.

And to finish for today with a quote from Jon Duckett’s HTML book “Work is the refuge of people who have nothing better to do”.

Seem like it is time to sleep rather than work! Good night
