Ruby on Rails Test Fixtures

[bourea]

When I use test fixtures to populate test data into mysql database I am
running into an unexpected behavior. Only columns explicitly defined
in the fixture is populated into the database. However, created_on,
created_by, updated_on, updated_by fields along with all fields
normally populated by observers are NULL. For example, I have a couple
fields that have their values calculated via observers. I want to test
that these calculations are performed correctly by the observer, so I
don't want to hard code their values in the fixture.

Has anyone else run into this issue? If so, how did you perform
testing of these fields? I realize that I could perform these tests
without fixtures by creating and saving the object. Behind the scenes,
Active Record populates all the fields in the expected manner. Then I
could find the saved record and assert_equal the expected calculations.
However this approach seems brittle and I rather use fixtures. It
doesn't seem (from the results) that I am getting that the fixtures
functionality uses Active Record to serialize data to mysql.

Thanks!

Probably the Ruby on Rails mailing list will have lots of folks who
would be able to help. Here's info about it:
