Not understanding tests pass / fail process...

I may have missed something? Why does our test code in create_spec.rb pass with only "Hi" a 2 character set when we clearly put 3 minimum in our model validations?? shouldn't this fail the test?

Feel like I missed something but don't know what or where to review.... any advice would help thanks

So basically ( without seeing your code, I must assume ), your test is actually saying something like:

it "Should fail when trying to save with less than three letters" do

  # Set some model attribute to be three letters
  # Expect that it is invalid
end

You're actually testing that it is invalid when you save. So being invalid, is considered a passing test.

ah, kind of figured ... so we're actually testing that the test will catch errors (there for it passes) ..?
