I'm assuming expected_value looks something like this (and is not an array):

"DataType_Boolean false"

since if you call casecmp on an array it will return an undefined method error. If that's the case, you can continue to call include? to see if it matches.

if expected_value.include? "DataType_Boolean"
 # Check that the actual value should be either true or false.
 if expected_value.include?("true") || expected_value.include?("false")
 result = "Passed"
 end
end

If the above assumption is true, your second if statement will never return true because of the inclusion of the extra parts of the string.

  Please include the actual output of expected_value in your question as well as the rest of the method where the conditional is running.
