rspec users - Nov 2008 - Features and conditions for those to be executed

Hello Guys,

May this question be silly, so I''m exposing myself as a complete dumb
;-)

I''ve been working on a project called rake-compiler, which enable the
building of extension with C compilers in a standarized way.

http://github.com/luislavena/rake-compiler/tree/master

The thing is been driven by features and with some specs to guide me
in the task associations of rake, but not much after.

Now I have a problem: I want to introduce cross compilation which can
only be executed in certain environments, not all.

I have specs that tell me what will happen (what things will get
defined as rake tasks) and the chain, but I cannot execute it under
Windows.

Only under OSX or Linux can be executed (which I''m using right now to
drive it).

There is a way that I can exclude this feature from being executed in
this case? I will prefer to avoid having a feature list to maintain,
but if is the only choice, no problem.

Thanks in advance for the suggestions.

Assuming you''re writing a feature for a black box that works under
linux, osx but not under windows. Can you not write a features like

Given I''m on windows
When I run black box
I should get an error ...

Given I''m on OSX
When I run black box
I should not get an error ...

Just an idea, HTH

Yeah, your idea looks good.

Wonder if this should be defined as a pending step or it should
generate an skipped one?

You could use profiles in the cucumber.yml file. Rather than creating a 
long feature list you can exclude a feature from one profile.

Cucumber accepts:
-e, --exclude PATTERN            Don''t run features matching a pattern

@@@
windows: --format progress features --exclude pesky_windows_feature
mac:         --format progress features
@@@

Then run them with:
cucumber --profile windows
cucumber --profile mac

Thanks Joseph,

I will love to drive the "show" only using "rake features"
or by
calling cucumber features directly, thus avoiding to remember that
exclusion list.

BTW: the pesky feature will be OSX and Linux, not Windows, so the
pesky ones are posix, not Windows ;-)
