Ruby Ruby Foundations Testing MiniTest

I'm getting an uninitialized constant/name error while running ruby 1-test.rb

here is my code ....it worked fine when it was testing addition but now that I am testing the array it is giving me errors. Can anyone tell me what I have done wrong?

Code:

require 'minitest/autorun'

class MyTest < MiniTest::Unit::Testcase def test_that_addition_works assert_equal 4, 2+2 end

def test_that_my_array_has_a_value my_array = %w(dog cat frog) assert my_array.include?('frog') end end

Error message:

MadelynsMiniMac-2:~ madelynpapineau$ ruby 1-test.rb 1-test.rb:3:in `<main>': uninitialized constant MiniTest::Unit::Testcase (NameError) MadelynsMiniMac-2:~ madelynpapineau$

Glad I could actually help. This stuff can be really frustrating, and finding answers even more so. Nice to feel useful for once. :)

If you didn't retype the class definition between the first and second tests, I'm not sure why the first one passed. But I think the MiniTest parent module is returning an uninitialized constant error (assuming that what's printed above is cut-and-pasted) because the C in the two-word CamelCase "::TestCase" isn't capitalized. As far as Ruby's concerned, TestCase and Testcase are as different as IceCream and HeffalumpNostrils. Kinda finicky, I know...:)
