Using XCTest to test SwiftUI apps

When we build an app and implement the different features, we need to test that the app works correctly. Testing an app manually is a repetitive and time-consuming process, which becomes very boring. It is very common to make mistakes when performing boring and repetitive tasks. These mistakes could lead to the release of an app with defects to the App Store, affecting our users. Luckily, with the help of test automation, we can make Xcode test the app for us. Test automation is a very important discipline in software engineering and is based on the use of automated tests, with different levels of abstraction. The automated tests verify that the app under test works according to a well-known specification. Automated tests are a part of the software development process, and they verify that the code changes did not inadvertently introduce defects. With adequate automated test coverage, we have a higher confidence level, and we can catch the code defects...
