22 /** @brief Setup the expectations for sdbus-based object creation.
23  *
24  * Objects created that inherit a composition from sdbusplus will all
25  * require at least these expectations.
26  *
27  * If you have future sd_bus_emit_properties_changed_strv calls expected,
28  * you'll need to add those calls into your test.  This only captures the
29  * property updates you tell it to expect initially.
30  *
31  * TODO: Make it support more cases, as I'm sure there are more.
32  *
33  * @param[in] sdbus_mock - Pointer to your sdbus mock interface used with
34  *     the sdbusplus::bus_t you created.
35  * @param[in] defer - Whether object announcement is deferred.
36  * @param[in] path - the dbus path passed to the object
37  * @param[in] intf - the dbus interface
38  * @param[in] properties - an ordered list of expected property updates.
39  * @param[in] index - a pointer to a valid double in a surviving scope.
