問題文
A solution spans a sales app and a service app, and the business process hands a record from one to the other. The architect designs end-to-end test scenarios. What must the scenarios cover that single-app tests do not?
選択肢
- The license assignment of each user, because handoffs fail when licenses differ.
- The handoff itself, including whether the context and identifiers survive the transition between the two apps.
- The user interface layout of each app, because visual differences confuse users during handoff.
- Nothing additional, because if each app passes its own tests then the records exchanged between them have already been checked on both sides of the boundary they cross.
