Load fixtures

Rails
1

I’m finally getting beyond using basic test fixtures, and a few
questions
have popped up. Has anyone found ways to do these?

  1. Use a test fixture that is named differently from its table name?
    We’d like
    to have more than one possible fixture per table. (Or perhaps use test
    fixtures
    named similarly but in different directories.)

  2. Load a test fixture for one test method only in a test file (and not
    for the
    other test methods in the source file)? Thought I had a way to do this
    using
    Fixtures.create_fixtures and Fixtures.instantiate_fixtures, but it
    messed up the
    deleting of other fixtures’ data at the start of the next test method.

Thanks,
Kian W

There’s no way to do #1 in the existing fixture code.
The closest you can come is by using the new-ish subfolder fixture code.

If your table is named ‘examples’
…you can have /test/fixtures/examples.yml be an empty file.
Then, in /test/fixtures/examples/, place as many fixtures with any
filenames you wish.
The drawback is that the fixtures still need to be uniquely named. If
you have test/fixtures/examples/group_one.yml and group_two.yml, a
fixture named examples(:blah) can only exist in one of them at a
time.

I did a patch a while ago that changed this, but it hasn’t gotten much
love, and may not apply cleanly to the current version. I should
probably turn it into a plugin, but it wouldn’t be fun to maintain,
given the structure of the fixtures code.

You can find it here if you’re interested:

Thanks. But it appears that I still have to load all the fixtures in the
‘examples’ directory, right? I really want to be able to selectively
load only
certain fixtures for a given table.

I tried ‘fixtures “examples/group_one”’, but that fails (something about
no
table named ‘group_one’, which makes sense).

I also tried separate subfolders, e.g., ‘example1’ and ‘example2’, each
with a
YAML file named after the table. It doesn’t error, but it doesn’t appear
to load
the fixture either.

Wilson’s patch looks interesting; so does the Flexible Fixtures one
http://dev.rubyonrails.org/ticket/1911. Hopefully 1.1.3 will beef up
support for
fixtures.

Any suggestions?
