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

RS( sD Works like a regular Werkzeug test client but has some knowledge about
how Flask works to defer the cleanup of the request context stack to the
end of a ``with`` body when used in a ``with`` statement. 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 :ref:`testing` chapter.

� Wd QXd S( s� When used in combination with a ``with`` statement this opens a
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.

:meth:`CliRunner.invoke <click.testing.CliRunner.invoke>` for
full method documentation. See :ref:`testing-cli` for examples.
If the ``obj`` argument is not given, passes an instance of
:class:`~flask.cli.ScriptInfo` that knows how to load the Flask
app being tested.
:param cli: Command object to invoke. Default is the app's
:attr:`~flask.app.Flask.cli` group.
:param args: List of strings to invoke the command with.
:return: a :class:`~click.testing.Result` object.
