//! Multiple scenarios that are performed to test sync operations correctly work
//!
//! This module creates test data.
//! To do so, "scenarii" are defined. A scenario contains an inital state before sync, changes made either on the local or remote side, then the expected final state that should be present in both sources after sync.
//!
//! This module builds actual CalDAV sources (actually [`crate::cache::Cache`]s, that can also mock what would be [`crate::client::Client`]s in a real program) and [`crate::provider::Provider]`s that contain this data
//!
//! This module can also check the sources after a sync contain the actual data we expect
