rspec users - Jun 2010 - I'm having a couple of nuisance things happening with jruby and rspec

Hi all,

I have a couple of things that are happening when using jruby.

1) I consistently getting a ''Command <cmd> failed''
raised when using rake.  The Kernel.system() call on line ~ 176 of
lib/spec/rake/spectask.rb is always returning false.  I''m not sure why.
The specs run and work.  Does anyone or has anyone have this happen?  I run
without rake and it works fine.  It''s as if the Kernel.system() call is
returning a negative false condition all the time.  jruby issue?

2) jruby on Windows does not produce colors.  I tried piping to wac and it
parses out the color chars, but everything is still mono.  If I add a puts in my
spec file with color chars that will be in color but the spec run will be in
mono.  It is like rspec gem is doing something funky with the terminal/console
output stream if it is jruby.  Any ideas here?

jruby 1.5

Here is my gem list:

*** LOCAL GEMS ***

actionmailer (2.3.8, 2.3.5)
actionpack (2.3.8, 2.3.5)
activerecord (2.3.8, 2.3.5)
activeresource (2.3.8, 2.3.5)
activesupport (2.3.8, 2.3.5)
builder (2.1.2)
columnize (0.3.1)
faker (0.3.1)
jruby-openssl (0.7)
machinist (1.0.6)
rack (1.1.0, 1.0.1)
rails (2.3.8, 2.3.5)
rake (0.8.7)
rspec (1.3.0)
ruby-debug (0.10.3)
ruby-debug-base (0.10.3.2)
sequel (3.12.1, 3.11.0)
sources (0.0.1)


I have to use jruby and windows for these tests.  The Rails ENV is used just for
convenience of loading gems.  This is not a web app.  I''m using rspec
to unit test DB stored procedures.

Thanks in advanced for nay insight to why I''m getting these,

hmm..

for issue 1)
I''ve found that rake doesn''t always give an informative
message

I''ve gotten better messages when I run the spec command directly:

if you run rake spec you might see something like this after your tests run
Command /Users/home/Projects/jruby/jruby-1.5.0/bin/jruby -I"spec:lib"
"/Users/home/Projects/rcov/rspec/bin/spec" <ALL YOUR SPEC FILES
HERE>


if you copy and paste everything from JRuby on (e.g.
/Users/home/Projects/jruby/jruby-1.5.0/bin/jruby -I"spec:lib"
"/Users/home/Projects/rcov/rspec/bin/spec" <ALL YOUR SPEC FILES
HERE>)

and run that... you might get a better message.

Jay,

Yes, I have done this and yes I don''t get any error messages.  But the
command ran from rake fails and rake aborts.  It is like the rake task in rspec
using Kernal.system is returning with a negative false here in the code:

line 176 in lib/spec/rake/spectask.rb

              unless system(cmd)
                STDERR.puts failure_message if failure_message
                raise("Command #{cmd} failed") if fail_on_error
              end

the cmd does not fail, but returns false.  failure_message is nil obviously.

Is this a jruby issue?  a jruby on windows issue?  Hard to figure out why it
returns false when the command works.
