Simpletest: Errors because of UbercartTestHelper class

Where do you see this error? All SimpleTests work and pass for me, and the testbot on drupal.org agrees.

If you've updated your Ubercart site recently, it may be that you need to clear the cache in order to rebuild the class registry. UbercartTestHelper is in uc_store/uc_store.test.

@TR: but there is no class registry in D6, is there? Perhaps we need the same code that's in uc_order.test in D6:

// Ensure UbercartTestHelper is available.
module_load_include('test', 'uc_store', 'uc_store');

Oh yeah. D6. No there's no class registry in D6. I don't see how this can happen then, or rather I don't see how this can happen on one site and not on another, unless there's a stale cache involved (maybe Boost or Pressflow or APC or some other non-core Drupal caching?).

I seem to remember having to add that code to uc_order.test as SimpleTest was loading it before uc_store.test, and the helper wasn't found in some cases. Perhaps the sequence of file loading is server dependent somehow - directory/filename order in the file system perhaps?

@jepSter: can you try adding the code from #3 to uc_cart_links.test and see if that helps?

Committed code from #3 to uc_cart_links.test which should fix this.
