S )EnvironBuildera  An :class:`~werkzeug.test.EnvironBuilder`, that takes defaults from the
    application.

    :param app: The Flask application to configure the environment from.
    :param path: URL path being requested.
    :param base_url: Base URL where the app is being served, which
        ``path`` is relative to. If not given, built from
        :data:`PREFERRED_URL_SCHEME`, ``subdomain``,
        :data:`SERVER_NAME`, and :data:`APPLICATION_ROOT`.
    :param subdomain: Subdomain name to append to :data:`SERVER_NAME`.
    :param url_scheme: Scheme to use instead of
        :data:`PREFERRED_URL_SCHEME`.
    :param json: If given, this is serialized as JSON and passed as
        ``data``. Also defaults ``content_type`` to
        ``application/json``.
    :param args: other positional arguments passed to
        :class:`~werkzeug.test.EnvironBuilder`.
    :param kwargs: other keyword arguments passed to
        :class:`~werkzeug.test.EnvironBuilder`.

    Flask's contexts to defer the cleanup of the request context until
    the end of a ``with`` block. For general information about how to
    use this class refer to :class:`werkzeug.test.Client`.

    .. versionchanged:: 0.12
       `app.test_client()` includes preset default environment, which can be
       set after instantiation of the `app.test_client()` object in
       `client.environ_base`.

    Basic usage is outlined in the :doc:`/testing` chapter.

        session transaction.  This can be used to modify the session that
        the test client uses.  Once the ``with`` block is left the session is
        stored back.

        ::

            with client.session_transaction() as session:
                session['value'] = 42

        Internally this is implemented by going through a temporary test
        request context and since session handling could depend on
        request variables this function accepts the same arguments as
        :meth:`~flask.Flask.test_request_context` which are directly
        passed through.
