Thanks JD!!
It never occurred to me that I can store the number in a @n_number variable
and use it later. Here is the version that is working perfectly:
I will be interested to know if people are actually using Cucumber in their
companies to write acceptance tests.
Given /I have a negative number/ do
end
When "I pass the negative $n_number to the prime service" do |n_number|
@n_number = n_number.to_i
end
Then /the service should throw exception/ do
lambda {...@primeservice.isprime(@n_number)}.should raise_error
end
