The following code works but there is nothing in the feature that I can say
that the exception is thrown.
Given /I have a negative number/ do
end
When "I pass the negative $n_number to the prime service" do |n_number|
lambda {...@primeservice.isprime(n_number.to_i)}.should raise_error
end
Then /the service should throw exception/ do
end
