This may appear as an unnecessary effort to refactor, or worse,
normalize a code that can benefit from some diversity
yet,
the forms

   (should
    (equal "<str result>"
      (org-test-with-temp-text "<block>"
      (org-babel-next-src-block)
      (org-trim (org-babel-execute-src-block))))))

or

(org-test-with-temp-text "<block>"
     (org-babel-next-src-block)
     (should (equal '(<something>) ;; or (should (string= "<str>
        (org-babel-execute-src-block))))
;; or org-babel-execute-maybe for ruby and elisp

exist in
test-ob-[maxima,R,sqlite,sed,shell,plantuml,lua,java,julia,lob,octave,perl,python,emacs-lisp].el

Considering it at the repetitive pattern, I think a macro can shorten
those forms to :

(ob-test  "<preamble + block>"
   :expect  "<expected-result>")

and a variant to test or exclude matching regexp

(ob-test  "<preamble+block>"
   :expect-to-match  "<expected regexp to match>")

(ob-test  "<preamble+block>"
   :expect-to-not-match  "<expected-regexp to not match>")

IMHO, they would be easier to read with one additional line feed

   (ob-test  "
#+begin_src ...

#+end_src"
             :expect  "<expected-result>")

rather than

    (ob-test  "#+begin_src ...

#+end_src"
              :expect  "<expected-result>")

Similar macro/function exists in
ob-emacs-lisp/dynamic-lexical-execute
or ob-sql/command-should-contain.

my 2¢,
