Hi,
I am using JRuby (trunk) and wrote a bunch of specifications for my
code. Everything works fine so far.
Now I am trying to integrate RCov in my test run. I have installed
RCov without the C extensions. I tried it with a simple script and it
worked (pretty slow, but it doesn´t matter).
But when I add the rcov options to my Rake task, RCov is not invoke
properly!
Rakefile:
Spec::Rake::SpecTask.new(‘specs’) do |t|
t.spec_files = FileList[‘spec/**/*.rb’]
t.rcov = true
t.rcov_opts = [’–exclude’, ‘spec’]
t.verbose = true
end
Output:
…

Why is rcov started at the end of the test run?

This is Test::Unit output

Did you mean: Why is Test::Unit started at the end of the RSpec run?
I’m not sure exactly what you’re asking.

This is not Test::Unit output!
As you can see I created a Rake task to run my specs and tried to
integrate rcov as described on
http://rspec.info/documentation/tools/rcov.html
RSpec works as expected (187 examples, 0 failures, 10 pending) but I
am missing the RCov report.

Ok, so the question is then why I don´t get an RCov report? Sorry for
the “test run”. Better call it an RSpec run?

The following text - taken from your first email - is Test::Unit
output. It is not RCov or RSpec output.

In your first email you asked: Why is rcov started at the end of the

I got confused about what you mean by “test run” (that usually mean
Test::Unit run - and you do have Test::Unit output).
Are you trying to figure out what order things are happening in, or
are you trying to figure out why you’re not getting an RCov report?

RSpec run is much clearer, thanks 
I’m looking into the problem, but I’m struggling to install RCov into
JRuby. I get the following error:
$ /usr/local/jruby-1.1RC2/bin/jruby -S gem install rcov
Building native extensions. This could take a while…
extconf.rb:1: no such file to load – mkmf (LoadError)
ERROR: Error installing rcov:

Gem files will remain installed in
/usr/local/jruby-1.1RC2/lib/ruby/gems/1.8/gems/rcov-0.8.1.2.0 for
inspection.

/usr/local/jruby-1.1RC2/lib/ruby/gems/1.8/gems/rcov-0.8.1.2.0/ext/rcovrt/gem_make.out
How did you install rcov bypassing the building of the C extensions?
Aslak
- Download eigenclass.org and
extract the archive
- jruby -S setup.rb all --without-ext
- Change shebang of /bin/rcov to #!/usr/bin/env jruby
- rcov script.rb should work now (warning appears, that no extensions
are installed)

Thanks, those installation instructions were useful.
Unfortunately, I’m unable to run RCov 0.8.1.2 on JRuby 1.1.RC2 at all:
$ /usr/local/jruby-1.1RC2/bin/jruby -S rcov --version
Exception in thread “main” java.lang.RuntimeException: MethodBlock
does not have a static scope; this should not be called
at
org.jruby.runtime.MethodBlock.getStaticScope(MethodBlock.java:128)
at org.jruby.RubyModule.createProcMethod(RubyModule.java:1079)
…
(lots more)
…
at org.jruby.Main.main(Main.java:79)
Can you recommend a JRuby version where RCov will actually start up?

Issue is solved!!!
I had a require ‘test/unit’ in my spec_helper.rb. I removed it and it
works now.

That´s right, sorry! There was a call and it will be fixed in RC3.
But you can checkout the sources
(http://svn.codehaus.org/jruby/trunk/jruby/
) and build the jruby.jar via ant.
It will work then!
I know it´s complicated, but I need this for my diploma thesis and I
appreciate your help!

Good. That makes sense. Two competing exit hooks or something. I bet
your Test::Unit output went away too.
