Testing SwiftUI

This lesson is part of Swift · All levels

Summary

This lesson discusses the automated testing strategy for SwiftUI applications. Developers will learn the differences between the Testing Unit to validate the ViewModel business function using the XCTest framework, as well as UI Testing to test user screen interaction flow automatically through button-touch simulation.

Key points

The Testing Unit tests the functions, calculations, and logic of the ViewModel in isolation
UI Testing simulates user interactions in real time using the XCUIApplication
Assertive functions such as 'XCTAssertEqual()' and 'XCTAssertTrue()' validate the expectation of test results
ViewInspector is a popular third-party library for performing unit tests directly on the SwiftUI view hierarchy
