For nonurgent messages, texting is a more efficient approach. In a distributed processing environment, message queuing is similar, although the speed and volume of messages are much greater. This approach is common in transaction-intensive environments in which teams perform the same tasks repetitively.

Interestingly, Xcode provides a testing framework called XCTest to write unit tests, performance tests, and UI tests. Unlike unit tests which are tested in isolation, UI testing is performed on the integration of the multiple classes. We can use these documented statistics to improve the testing and application performance.
