When evaluate below codes, I get unexpected result.
(defvar test 1)
-> test
It is expected.
(defvar test 2)
-> 2
It should return 'test'.
(symbol-value 'test)
-> 2
It should return 1.

When you say "evaluate", what do you mean? Doing `C-x C-e' after the
form? If it's the latter, then the doc string explains what's
happening (and this is new behaviour in Emacs 28):
----
C-x C-e runs the command eval-last-sexp (found in global-map), which
is an interactive compiled Lisp function in ‘elisp-mode.el’.
It is bound to C-x C-e.
(eval-last-sexp EVAL-LAST-SEXP-ARG-INTERNAL)
Probably introduced at or before Emacs version 24.4.
Evaluate sexp before point; print value in the echo area.
Interactively, with a non ‘-’ prefix argument, print output into
current buffer.
This commands handles ‘defvar’, ‘defcustom’ and ‘defface’ the
same way that ‘eval-defun’ does. See the doc string of that
function for details.

I meant C-j in *scratch* buffer (eval-print-last-sexp) and `C-x C-e'.
They return the same result. I didn't notice the change of
eval-last-sexp, sorry. I'm closing this issue.
