This is still failing the tests, and I can't see why, I suspect the
reason is in the "... ..." below:

Test check-for-wrong-custom-opts condition:
    (ert-test-failed
     ((should (null (cus-test-opts t))) :form
      (null ((gnus-valid-select-methods :type-error ... ...))) :value nil))
   FAILED  1/1  check-for-wrong-custom-opts (13.744560 sec) at misc/test-custom-opts.el:33

I've edited test-custom-opts.el to let-bind
`ert-batch-print-level/length' to nil around the (cus-test-opts t) call,
but that doesn't change anything -- can anyone tell me how to expand the
output there?

Thanks,
Eric

that precedes the ERT error. In this case, it appears that the top-level list includes an element

  ("nnatom" address)

which doesn't match the declared type which requires that the string be followed by one of {post, mail, none, post-mail}.

This should be changed to `("nnatom" none address)', and the docstring
should probably be changed to clarify this too.

Honestly though, I don't understand why this is a user option in the
first place, it only seems useful if you're implementing a new backend
(in which case, you're probably using `gnus-declare-backend', which
modifies `gnus-valid-select-methods' without checking the value anyway).

That's what I've changed it to, and it was still failing, that's why I
was trying to dig more information out of the failure.

HOWEVER. Moments ago I thought to look at nnatom.el itself, and this bit
at the bottom:

(gnus-declare-backend (symbol-name nnatom-backend) 'address)

Also ends up setting gnus-valid-select-methods, and needs the equivalent
change:

(gnus-declare-backend (symbol-name nnatom-backend) 'none 'address)

And here you mention that exact fact :)

I agree it doesn't make much sense, it doesn't do anything for the user.
I wonder if `gnus-declare-backend' was originally just meant to be used
by out-of-tree backend libraries.

Anyway, it's redundant, but no great harm done, and the tests pass.

Maybe the Gnus manual should indicate that `gnus-valid-select-methods'
should be modified directly for built-in backends (currently it only
describes using `gnus-declare-backend' in Hooking New Backends Into Gnus).

    > Anyway, it's redundant, but no great harm done, and the tests pass.

Thanks.
I also realized there is an example in nnfeed.el which is wrong in the
same way, I've attached a patch which fixes it.
