Re: Sorry if this is a stupid question

Hi everyone

I am trying to run the CS examples using Iron ruby/ cucumber from the
download and have hit a really irritating snag

I have added a subtract method to the CS calculator - Re compiled -
Added a features file for it and when I run I get the following

Scenario: subtract two numbers #
features/subtraction.feature:

6

Given I have entered 70 into the calculator

And I have entered 50 into the calculator

When I press subtract

Then the result should be 20 on the screen

And the result class should be Fixnum



|input_1|input_2|button  |output|class |

|30     |20     |subtract|10    |



  expected: 0,

       got: 10 (using ==)

  Diff:

  @@ -1,2 +1,2 @@

  -0

  +10 (Spec::Expectations::ExpectationNotMetError)

  features/subtraction.feature:15:in `/the result should be (.*) on

the scre

en/’

As you can see the calculator returns the right number (10) but somehow
the features file is expecting 0??? Even though I have defined 10 as the
result?

Can anyone help me - I’m doing my head in

Below is the subtract method from the steps file and the result compare

When /I press subtract/ do

@result = @calc.Subtract

end

Then /the result should be (.*) on the screen/ do |result|

@result.should == result.to_i

end

Those features look out of date to me. The Scenarios / More Examples
format has been deprecated in the latest version on Github.

Which version of cucumber are you using?

Try this instead:

I installed it via the Gem package manager ?

The version I have installed is cucumber-0.1.16

And I have just re written the features file as suggested in the link
and it works

Weird that the addition in the examples works even though it is in the
older format??

Thanks Heaps - I can now keep what little hair I have left
