Solve the following python programming problem given the following code:
@ pytest.fixture (autouse = True) 
def _push_request_context(request) : 
    "During tests execution request context has been pushed, e.g. `url_for`,
    `session`, etc. can be used in tests as is::

        def test_app(app, client):
            assert client.get(url_for('myview')).status_code == 200

    " 
    if ('app' not in request.fixturenames) : 
        return 
app = request.getfuncargvalue ('app') 
    if ('live_server' in request.fixturenames) : 
        app = request.getfuncargvalue ('live_server').app 
ctx = app.test_request_context () 
    ctx.push () 
    def teardown() : 
        ctx.pop () 
request.addfinalizer (request)
