Rails - Jul 2005 - unit test questions

A few unit test questions:

1. When running unit tests with rake, is there a way to create test  
result HTML pages like JUnit does?
2. I noticed weird behavior when I had fixtures that were dependent  
on each other, e.g. :
  fixture foo
---------------
  foo_example
    id: 1
    name: hello

fixture bar
---------------
bar_example
    id: 1
    foo_id 1

   a.  I found that the fixtures must be loaded in the reverse order  
that they should be deleted, i.e.  I must specify  
"fixtures :foo, :bar" with :foo first, otherwise I get DB constraint  
errors when the unit tests try to clear out the tables.  Is this  
documented anywhere?
   b.  I found that I must include the dependent fixture, even if it  
is not used in my test.   For example, FooTest must include the :bar  
fixture, or else I get the same DB constraint errors.  Is this  
correct behavior?

thanks,
Jeff

Hi,

I''ve seen that behavior too. First I found it annoying, but later I saw
the benefit from it:
- the db constraints help you find errors in your fixtures (for example 
you made a mistake specifying some non existent foo_id)
- they make you think/understand more about your db schema
- the db constraints help you identify models where you need to add 
validations (validates_presence_of and the like)

I don''t know exactly where it is documented, but I found info on it in 
the wiki (would have to search to find it right now) and in the 
mailinglist here.

regards,
Bas
