So the canonical data is a bit off for this exercise. There are several tests in the canonical data that are expecting a method named encode or possibly encoded to be defined on the Crypto class. However, this method is missing from crypto_square.rb

def workload
return if property == 'encoded'
fix_canoncical_expected_value
indent_lines(["crypto = Crypto.new('#{plaintext}')",
"assert_equal #{expected}, #{actual}"
], 4)
end

private

def actual
case property
when 'normalizedPlaintext'
'crypto.normalize_plaintext'
when 'plaintextSegments'
'crypto.plaintext_segments'
when 'ciphertext'
ciphertext_method_call
end
end

def expected
canonical.expected.inspect
end

def ciphertext_method_call
if canonical.expected.include?(' ')
'crypto.normalize_ciphertext'
else
'crypto.ciphertext'
end
end

The canonical data for one test also has an extra space, which causes the assertion to fail.

def fix_canoncical_expected_value
return unless canonical.expected.include?(' ')
canonical.expected = canonical.expected.gsub(/\s\s/, ' ').chomp(' ')
end

The canonical data had a test which asserts that an empty array passed into Crypto.plaintext_segments will return an empty array. However, the current Crypto class just blows up when it tries to call each_slice with a size of 0.

So these tests seemed to have assertion that differed from what the canonical data wanted.
I went with the canonical data's choice of assertions, because I figured it was more up-to-date.
