Can't run any tests at all

Hi all,

I've been playing around with Rails off and on for a while now, and suddenly I am unable to run any unit tests of any kind under Rails. Or perhaps more specifically, using the Rake task test_units in a rails project. This applies to any rails project I create. Unit tests, functional tests, etc. I *swear* I used to be able to run tests, but now I can't, and cannot for the life of me figure out why.

I am on Windows XP, *not* running under Cygwin, but this has never been a problem before, running Ruby 1.8.4-20 and Rails 1.2.3 to mirror what my host provider has. The RoR website says 1.8.4 is still viable with the latest Rails release, so I assume this is not an incompatibility issue. I am also using Rake 0.7.3 as installed when installing the Rails gem, though 0.7.1 was already installed by default.

For this example, I created a barebones Rails app called "example" and tried to test, using these steps:

== begin snippet ==

rails example

     ... generated project

ruby script\generate model Foo

     ... generated model and foo_test.rb

rake test_units

(in C:/Dev/projects/rails/example) C:/Dev/languages/ruby/1.8.4-20/bin/ruby -Ilib;test "C:/Dev/languages/ ruby/1.8.4-20/lib/ruby/gems/1.8/gems/rake-0.7.3/lib /rake/rake_test_loader.rb" "this is test in process" C:/Dev/languages/ruby/1.8.4-20/lib/ruby/gems/1.8/gems/rake-0.7.3/lib/ rake/rake_test_loader.rb:5:in `load': no such file to load -- this is test in process (LoadError)         from C:/Dev/languages/ruby/1.8.4-20/lib/ruby/gems/1.8/gems/ rake-0.7.3/lib/rake/rake_test_loader.rb:5         from C:/Dev/languages/ruby/1.8.4-20/lib/ruby/gems/1.8/gems/ rake-0.7.3/lib/rake/rake_test_loader.rb:5 rake aborted! Command failed with status (1): [C:/Dev/languages/ruby/1.8.4-20/bin/ ruby -I...]

(See full trace by running task with --trace) == /end snippet ==

Here's the really weird part: I cannot find ANY trace of the phrase "this is test in process" or even "test in process" anywhere in (a) Rails, (b) Ruby, (c) any Ruby gems. Nor can I find either phrase anywhere via Google in any way related to Rails (or even Ruby) unit testing.

If I manually run the default unit test, it works FINE:

== begin snippet == test\unit> ruby foo_test.rb Loaded suite foo_test Started . Finished in 0.203 seconds.

1 tests, 1 assertions, 0 failures, 0 errors == /end snippet ==

I tried assuming that "this is test in process" is something that perhaps I wound up adding or modifying in my tinkering, so I did the following:

1) Removed Rails and re-installed. Didn't work. 2) Completely removed Ruby and Ruby gems, and re-installed both, then re-installed Rails. Didn't work.

I am now completely stumped. Has anyone run into this behavior before, or otherwise know why this is happening and (more importantly) what I can do to get the rake task running again?

Thanks in advance, -dave

I should have clarified, I ran the rake task "test:units" rather than "test_units", but EITHER of them results in the same error output shown in the previous post.
