Test::Unit 2.x tests run from rake but fail from autotest

I'm having problems running my Rails unit tests via autotest using Test::Unit 2.0.6. Running tests via rake test:units works perfectly, but when I run the tests from autotest, I get this:

Versions:

• Mac OS X 10.6.3
• ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0]
• Rails 2.3.5 (based on Suspenders)
• autotest (4.3.2)
• autotest-fsevent (0.1.3)
• autotest-growl (0.1.7)
• autotest-rails (4.1.0)
• ZenTest (4.3.3)
• test-unit (2.0.6)

The problem also occurs with test-unit 2.0.9. I've tried the suggestions in Getting uninitialized constant error when trying to run tests and at http://floehopper.lighthouseapp.com/projects/22289-mocha/tickets/50, but still no luck.

Autotest works just fine if I remove the assertions that require Test::Unit 2.x and remove the test-unit gem. Unfortunately, I need to use the 2.x assertions.

Any ideas? Thanks in advance for any assistance.

I'm having the same problem: tests work fine when run from rake. But when I try autotest I get the same errror:

`const_missing': uninitialized constant Test::Unit::TestResult::TestResultFailureSupport (NameError)

I'm running shoulda 2.10.3, mocha 0.9.8, and test-unit 2.1.0. I had already monkeyed around with gem loading order to make mocha and shoulda happy and as I said things are fine with rake test. I've tried multiple versions of ZenTest (4.3.3, 4.1.1). I've tried a standalone version of autotest (4.3.2). Same results. I've tried using test-unit 1.2.3 instead of 2.1.0 but that breaks other parts of my tests.

I ran into a similar issue, and while I know this is really late, the problem was that I didn't have autotest-rails installed.
