Question

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:

/Code/projectdir/vendor/rails/activesupport/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant Test::Unit::TestResult::TestResultFailureSupport (NameError)

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