[Ironruby-core] Cucumber / RSpec Story Runner

Wed Oct 22 02:21:58 EDT 2008

Great - I have it working now on my machine.

I'm seeing 0.45s or so as the net time (excluding startup) for the tests if I run using the -X:Interpret flag. Can you try running with that flag enabled on your machine and let me know how quickly it runs?

Thanks,
-John

Sure. Here's the entire contents of the ruby file

$LOAD_PATH << 'c:/dev/rspec/lib'

require 'spec'

module ActiveSupport; end # workaround ironruby defined? bug

class Vehicle
  def initialize(people)
    @people = people
  end
  attr_accessor :people
end

describe Vehicle do
  it "should assign people using the constructor" do
    car = Vehicle.new(['orion', 'john', 'jim'])
    car.should have(3).people
  end
end

Note I'm not using gems or anything else like that. To replicate this you'd basically do this:

svn checkout ironruby 168 into c:\dev\ironruby

rake compile

git clone rspec straight from github, and stick it in c:\dev\rspec

edit c:\dev\rspec\lib\spec\extensions\main.rb and fix the call to File.expand_path

spin up a command prompt and set PATH=blahblah so it can see the ironruby binaries that got build previously

ir rspectest.rb

Orion - can you supply us with your rspectest.rb file?

I was just hacking around with rspec 1.1.9 here, and it's blowing up with a bunch of dependencies on startup.

Thanks,

The nested defined? bug is logged here:

http://rubyforge.org/tracker/index.php?func=detail&aid=22503&group_id=4359&atid=16798

The 'caller' one is actually 2 bugs, both of which have been logged by ben hall already

http://rubyforge.org/tracker/?group_id=4359&atid=16798&func=detail&aid=22315
http://rubyforge.org/tracker/?group_id=4359&atid=16798&func=detail&aid=22348

For those interested in running rspec right now, a better fix is to replace line 26 of main.rb with

args.last[:spec_path] = File.expand_path( caller(0)[1].split(':').first )

This will only cause rspec to lose the line number - you also have to run ir with the -D flag, or it doesn't include the path at all.

As far as my quick-hack investigation shows me, rspec only uses this data for showing friendly error messages, rather than any core logic, so perhaps it's not super-critical.
It would be nice to run it unpatched tho, IronRuby is looking incredibly close to doing that :-)

I'll add a rake task to compile release. Can you try to isolate those cases and file bugs? The second one is pretty easy, but I'd like to have tracking on both of them.

I just ran rspec 1.1.9 (straight from github) on IronRuby build 167, and it appears to work (I only have a simple test, but hey).

I only had to make 2 changes:

rspec\lib\spec\extensions\main.rb:26 is

args.last[:spec_path] = File.expand_path(caller(0)[1])
IronRuby still doesn't seem to handle caller quite the same as MRI. I have no idea what that code is for, but I replaced it with this as a quick hack

args.last[:spec_path] = "."

and it seemed to work.
I encountered another problem using the 'have' matcher - rspec does this

if inflector = (defined?(ActiveSupport::Inflector) ? ActiveSupport::Inflector : (defined?(Inflector) ? Inflector : nil))
IronRuby throws uninitialized constant Object::ActiveSupport, whereas MRI just returns nil - it looks like IR isn't handling defined? on nested things properly yet.

To work around this I just put

module ActiveSupport; end
at the top of my ruby file to get around the nested module issue.

And presto!

C:\development\irtest>ir rspectest.rb

.

Finished in 2.072133 seconds

1 example, 0 failures

C:\development\irtest>ruby rspectest.rb

.

Finished in 0.053 seconds

1 example, 0 failures

The only problem now is that 2.07 seconds is somewhat larger than 0.053... I am using the debug build of ir though, as that's what rake:compile seems to give me.

Just playing with VS now to see if I can build a release version and try that

Hi,

To get rspec to work you will need to modify the actual Ironruby

source.  I've raised bugs to get the changes required fixed, however I

did this based on 1.1.4, I think Cucumber will have a whole load more

bugs attached as it has more dependencies.

I know for a fact you won't be able to run Cucumber unmodified due to

existing bugs around gems.  (for example, gem needing .rb at the end

of the file to be able to find it)

However, I haven't had chance to take a closer look.

If you explicitly set the GEM_PATH before requiring gems, you should be able to use gems that are already present.  I haven't tried any other gem operations.

I assume you're running with the latest source?

Subject: [Ironruby-core] Cucumber / RSpec Story Runner

Has anyone tried to get Cucumber (or it's predecessor: the RSpec story

runner) to work with IronRuby?  I have not had any luck thus far (I am

extremely new to Ruby), and I would really like to be able to use

Cucumber to write executable feature documentation for my .NET code.

http://github.com/aslakhellesoy/cucumber/wikis

I copied it under the "lib" directory, as well as several of its

dependencies, but when I try to do "require

'cucumber-0.1.7/lib/cucumber'", ir (interactive ruby) fails with a stack

overflow.  The same thing happens when I try to require some its

dependencies manually (eg. "require 'hoe-1.8.0/lib/hoe'" and "require

'rake-0.8.3/lib/rake'"), but some work just fine (eg. "require

'polyglot-0.2.3/lib/polyglot'" and "require

'treetop-1.2.4/lib/treetop'").

I also tried to get gem working to aide me in this process, but I had

problems with that too.  Has anyone got gem working with IronRuby?

Thanks in advance!

Pat Gannon
