You are missing the lambda keyword. I would also just store the number at that
point, and perform the operation in the Then step.
When "I pass the negative $n_number to the prime service" do |n_number|
@n_number = n_number
end
Then /the service should throw exception/ do
lambda {[email protected](@n_number.to_i)}.should raise_error
end

I am having trouble in where to throw the exception. The exception will be
thrown in "When" and not "Then" as shown below:
Scenario Outline: Throw exception if the number is negative
Given I have a negative number
When I pass the negative <n_number> to the prime service
Then the service should throw exception
Steps:
Given /I have a negative number/ do
end
When "I pass the negative $n_number to the prime service" do |n_number|
lambda
{[email protected](n_number.to_i)}.should<mailto:%[email protected](n_number.to_i)%7d.should>
raise_error
end
Then /the service should throw exception/ do
end
The above throws the following exception:

To check for an exception: you need to get it into the form lambda { expr
}.should raise_error ErrorType where expr is your test expression, and
ErrorType is the type of the error you expect. In this case, you might need to
have the second feature read "When I pass the negative number <number> to the
prime service" so that you can parse it differently and just store the number,
then in the Then step for that negative number, you can do lambda {
@primeService.IsPrime(number.to_i) }.should raise_error Exception
Does that help?

Subject: Re: [Ironruby-core] Is there a But keyword in Cucumber?
Actually I also thought of that and I did separated them in multiple scenarios.
Now, I am having trouble writing the step.
Here is the feature file:
Feature: Prime Service
As a crazy person I need to know whether a number is prime or not
Scenario Outline: Find if the number if prime or not
Given I have a number
When I pass the <number> to the prime service
Then the service should display <result> indicating whether input is prime or
not
Examples:
| number| result|
| 1 | false |
| 2 | true |
| 3 | true |
| 4 | false |
Scenario Outline: Throw exception if the number is negative
Given I have a negative number
When I pass the <number> to the prime service
Then the service should return false
Examples:
| number|
| -1 |
| -2 |
| -3 |
| -4 |
And here are the steps:
require 'rubygems'
require 'spec/expectations'
require File.expand_path("bin/Debug/BusinessObjects.dll")
include BusinessObjects
Before do
@primeService = PrimeService.new
end
Given /I have a number/ do
end
When "I pass the $number to the prime service" do |number|
@result = @primeService.IsPrime(number.to_i)
end
Then /the service should display (.*) indicating whether input is prime or not/
do |result|
@result.to_s.should == result
end
Given /I have a negative number/ do
end
When "I pass the $number to the prime service" do |number|
@result = @primeService.IsPrime(number.to_i)
end
Then /the service should return (.*)/ do |result|
@result.to_s.should == result
end
Also, not sure how to check for exception right now!

You should probably split that into 2 scenarios. One for finding prime or not,
and one for throwing if the number is negative.
There might be an else construct, but I would argue that if you need an
else/but, then you have 2 behaviors in a single scenario.

I am using Cucumber and now I need to use a But keyword (if there is any)
Scenario Outline: Find if the number if prime or not
Given I have a number
When I pass the <number> to the prime service
Then the service should display <result> indicating whether input is prime or
not
But if the number is negative
Then the prime service should throw an exception
But it shows up as "Then" and not "But". Is there anything related to "But" in
Cucumber.
