1) Error:
test_truth(CommitmentTest):
NoMethodError: undefined method `reflect_on_all_associations' for Object:Class
1 tests, 0 assertions, 0 failures, 1 errors
The problem was happening when Rails was trying to load fixtures. Removing all the fixures removed the error. After adding back a few at a time, I narrowed the problem down to the Fixtures for an object called Content :
The Content object has a field called type, which is reserved for Single Table Inheritance. renaming that field solved the problem.
The vague undefined method `reflect_on_all_associations' can have a variety of sources, In general, it means there's a problem with a Model object.
