This 'check phase doesn’t respect the ‘--with-tests’ transformation.
Something like the following would be better:

  (replace 'check
    (lambda* (#:key inputs outputs tests? #:allow-other-keys)
      (when tests?
        (with-directory-excursion "tests"
          (add-installed-pythonpath inputs outputs)
          (invoke "py.test" "tests")))))

Otherwise, LGTM.
