Forum: IronRuby Cucumber with IronRuby

I don't know why I keep getting the following exception when I try to
run cucumber with Ironruby.

I have even updated the path in my icucumber.bat file as follows:

@ECHO OFF
REM This is to tell IronRuby where to find gems.
SET GEM_PATH=c:\ruby\lib\ruby\gems\1.8
@"C:\DevTools\ironruby-1.0-rc1\bin\ir.exe" "c:\ruby\bin\cucumber"

Looks like a syntax error where you have a identifier (method name or 
variable name) where a block is expected. Can you figure out where the 
error is being raised? The fact that it is in a method called 
"load_code_file" leads me to suspect it is one of the test files as 
opposed to the cucumber files.

Thanks for the reply! My test file called "primeservice.rb" is placed 
inside the step_definations folder which is inside the feature folder. 
Like this:

features/step_definations/primeservice.rb

The primeservice.rb looks something like this:


require 'rubygems'
require 'spec/expectations'

require File.expand_path("bin/Debug/BusinessObjects.dll")

include BusinessObjects

Thanks,
Azam

First of all upgrade to ironruby rc2.
Also I thought we had a very long discussion on mixing gems installed in 
a
different ruby. Let's not repeat that one and keep it at don't mix gem
installs.

then try this:

ir -S gem install cucumber ironterm-ansicolor
ir -S cucumber features/prime.feature

The ir-S gem install cucumber did not work:


C:\Projects\ILoveIronRuby\ILoveIronRuby\IronRubyConsoleApp>ir -S gem 
install cuc
umber ironterm-ansicolor
Option `-S' not supported

>> First of all upgrade to ironruby rc2.

Maybe later! I am afraid it will going to mess things up for me.

I installed the icucumber again using the following command:

igem install cucumber

the install went fine. then i said

icucumber on the command prompt and I got the following:

So, I tried installing the iron-term-ansicolor but I got the following:

C:\Projects\ILoveIronRuby\ILoveIronRuby\IronRubyConsoleApp>igem install 
iron-ter
m-ansicolor
ERROR:  While executing gem ... (IndexError)
    Index was outside the bounds of the array.

C:\Projects\ILoveIronRuby\ILoveIronRuby\IronRubyConsoleApp>

My feature file is called prime.feature and now I added a new test
file called "prime_steps" (I thought maybe the name has to be same).
After running the icucumber features/prime.feature I still get the same
error. The strange thing is that I don'nt have any code in the test
file. It is totally blank.

Try to run icucumber with the --no-color switch.

What does prime.feature look like then?

Here is prime.feature:


Feature: Prime Number Detection

I need to find if a number is prime or not

Scenario Outline: Prime Number Testing
Given I have a <number>
When I pass the number to a IsPrime method
Then I should get <result> indication prime or not

Examples:

| number | result | 
| 1      | true   | 
| 2      | true   | 
| 4      | false   | 


I ran without the --no-color and still getting the same issue:

That's why rc2 was FIRST. -S is an option added in rc2. If you want to 
support our project, we would appreciate it if you worked with the up to 
date bits so that we can be certain we aren't fighting against a 
resolved bug.

JD

Can you modify icucumber to run ir -d to turn on debug mode? That should 
give some logs that will help.

JD

I can perform the update but I am afraid that it will break my previous 
code and I cannot take that risk right now. Is there anyway to solve the 
issue on RC1?

Thanks,
Azam

When I type ir -d on the command prompt it takes me to the ironruby 
interactive console?

Can you modify icucumber to run ir -d to turn on debug mode? That should 
give some logs that will help. This is not the same as typing ir -d on 
the command line. This is modifying the icucumber.bat file you showed 
earlier to use the -d option. Then run icucumber feature/whatever like 
you were before.

JD

JD

Just modified the icucumber.bat to this:

@ECHO OFF
REM This is to tell IronRuby where to find gems.
SET GEM_PATH=c:\ruby\lib\ruby\gems\1.8
@"C:\DevTools\ironruby-1.0-rc1\bin\ir.exe -d" "c:\ruby\bin

\cucumber" %*


Now ran the icucumber and got the following:


C:\Projects\ILoveIronRuby\ILoveIronRuby\IronRubyConsoleApp>icucumber 
features/pr
ime.feature
'"C:\DevTools\ironruby-1.0-rc1\bin\ir.exe -d"' is not recognized as an 
internal
or external command,
operable program or batch file.

Get rid of the quotes. You don't have spaces in your path, so it 
shouldn't be needed. Can we also get you to join the mailing list so 
that the threads are preserved better? The ruby-forum isn't good for 
these long conversations.

JD

Here is the updated:

@ECHO OFF
REM This is to tell IronRuby where to find gems.
SET GEM_PATH=c:\ruby\lib\ruby\gems\1.8
C:\DevTools\ironruby-1.0-rc1\bin\ir.exe -d c:\ruby\bin\cucumber %*

still giving the same error and took 20 seconds to execute icucumber 
command.

Ok. We're missing something here. Let's take this offline. Email me 
personally, with a copy of your project if you can.

JD

to get a backtrace of what's happening you can run icucumber -b
features/prime.feature

Seems like the forums file attach limit is less then 1.5 MB (Are we 
living in the 80's? :)

Anyway, here is the url:

Heh, that's why I said send it to me offline. Anyways, addition.rb is 
pure ruby, you can't have the last three lines of the file as is.

JD

But I am trying to execute prime_steps.rb. Does it execute all of them 
by default or something??

I cannot believe it that was the problem. I deleted the addition.rb file 
and it started working. Lesson learned!! Cucumber will execute 
everything inside the step_definations.

It loads all of them by default

The thing is, you might have a login.rb file that has login steps, that 
is then used in all of your features that require logging in. It appears 
you can override automatic loading via -r, but otherwise, it has to load 
everything to be safe.
