/**
 * Add a mock environment to a widget.  This helper function can simulate
 * various kind of side effects, such as mocking RPCs, changing the session,
 * or the translation settings.
 *
 * The simulated environment lasts for the lifecycle of the widget, meaning it
 * disappears when the widget is destroyed.  It is particularly relevant for the
 * session mocks, because the previous session is restored during the destroy
 * call.  So, it means that you have to be careful and make sure that it is
 * properly destroyed before another test is run, otherwise you risk having
 * interferences between tests.
 *
 * @param {Widget} widget
 * @param {Object} params
 * @param {Object} [params.archs] a map of string [model,view_id,view_type] to
 *   a arch object. It is used to mock answers to 'load_views' custom events.
 *   This is useful when the widget instantiate a formview dialog that needs
 *   to load a particular arch.
 * @param {string} [params.currentDate] a string representation of the current
 *   date. It is given to the mock server.
 * @param {Object} params.data the data given to the created mock server. It is
 *   used to generate mock answers for every kind of routes supported by odoo
 * @param {number} [params.debug] if set to true, logs RPCs and uncaught Odoo
 *   events.
 * @param {Object} [params.bus] the instance of Bus that will be used (in the env)
 * @param {function} [params.mockFetch] a function that will be used to override
 *   the _performFetch method from the mock server. It is really useful to add
 *   some custom fetch mocks, or to check some assertions.
 * @param {function} [params.mockRPC] a function that will be used to override
 *   the _performRpc method from the mock server. It is really useful to add
 *   some custom rpc mocks, or to check some assertions.
 * @param {Object} [params.session] if it is given, it will be used as answer
 *   for all calls to this.getSession() by the widget, of its children.  Also,
 *   it will be used to extend the current, real session. This side effect is
 *   undone when the widget is destroyed.
 * @param {Object} [params.translateParameters] if given, it will be used to
 *   extend the core._t.database.parameters object. After the widget
 *   destruction, the original parameters will be restored.
 * @param {Object} [params.intercepts] an object with event names as key, and
 *   callback as value.  Each key,value will be used to intercept the event.
 *   Note that this is particularly useful if you want to intercept events going
 *   up in the init process of the view, because there are no other way to do it
 *   after this method returns. Some events ('call_service', "load_views",
 *   "get_session", "load_filters") have a special treatment beforehand.
 * @param {Object} [params.services={}] list of services to load in
 *   addition to the ajax service. For instance, if a test needs the local
 *   storage service in order to work, it can provide a mock version of it.
 * @param {boolean} [debounce=true] set to false to completely remove the
 *   debouncing, forcing the handler to be called directly (not on the next
 *   execution stack, like it does with delay=0).
 * @param {boolean} [throttle=false] set to true to keep the throttling, which
 *   is completely removed by default.
 *
 * @returns {Promise<MockServer>} the instance of the mock server, created by this
 *   function. It is necessary for createView so that method can call some
 *   other methods on it.
