Because they don't work.  I've reported it upstream at <https://github.com/rochacbruno/flasgger/issues/105>.

I guess not with tests disabled.

I'll keep trying to get it to work including the tests, but so far that requires the following new packages we didn't have:
- python-jsonpointer
- python-rfc3987
- python-validate-email
- python-flex

It also requires new native-inputs, finally ending up with:

(define-public python-flasgger
  (package
    (name "python-flasgger")
    (version "0.6.3")
    (source
      (origin
        (method url-fetch)
        (uri (string-append "https://github.com/rochacbruno/flasgger/archive/"
                            version ".tar.gz"))
        (file-name (string-append name "-" version ".tar.gz"))
        (sha256
          (base32
            "1gqzlm0rb55fdpsy5ipkganlx9cnpi454fqyycr03jm22zql14ay"))))
    (build-system python-build-system)
    (arguments
     `(#:phases
       (modify-phases %standard-phases
         (replace 'check
           (lambda* (#:key inputs outputs #:allow-other-keys)
             (substitute* "Makefile"
               (("flake8 flasgger --ignore=F403")
                "flake8 flasgger --ignore=E731,F403"))
             (setenv "PYTHONPATH" (string-append (getcwd)
                                                 ":"
                                                 (getenv "PYTHONPATH")))
             ;(zero? (system* "py.test"))
             (zero? (system* "make" "test"))
             ;#t
)))))
    (propagated-inputs
     `(("python-flask" ,python-flask)
       ("python-pyyaml" ,python-pyyaml)
       ("python-jsonschema" ,python-jsonschema)
       ("python-mistune" ,python-mistune)
       ("python-six" ,python-six)))
    (native-inputs
     `(("python-decorator" ,python-decorator)
       ("python-flake8" ,python-flake8)
       ("python-flask-restful" ,python-flask-restful)
       ("python-flex" ,python-flex)
       ("python-pytest-3.0" ,python-pytest-3.0)
       ("python-pytest-cov" ,python-pytest-cov)))
    (home-page "https://github.com/rochacbruno/flasgger/")
    (synopsis "Extract Swagger specs from your Flask project")
    (description "This package allows extracting Swagger specs from your Flask
project.  It is a fork of Flask-Swagger.")
    (license license:expat)))

And then the tests finally run and fail.

Let's wait for a few days whether there's an easy fix from upstream.  If not, we can still commit it with the tests disabled (ugh).
