unit testing swiftUI

To perform unit testing in SwiftUI, you can leverage the new Swift Testing framework introduced by Apple. This framework is designed to be expressive and easy to use, with features that integrate seamlessly with Swift concurrency and support for async/await and actor isolation. Here are some key points about Swift Testing:

1. Test Functions: You can write test functions by adding a @Test attribute. These functions can be global or methods within a type and can be marked as async or throws.

2. Expectations and Traits: Swift Testing uses macros like #expect and #require to evaluate test results. These macros allow you to pass ordinary expressions and use language operators for assertions.

3. Parallelization: Tests run in parallel using Swift concurrency, which can improve performance and efficiency.

4. Tagging System: Swift Testing includes a flexible tagging system to organize tests. You can group tests by tags and selectively run them based on these tags.

5. Parameterized Tests: You can easily parameterize tests to run the same test logic with different data inputs.

For more detailed information on Swift Testing, you can refer to the session Meet Swift Testing (00:01:46) from WWDC 2024, which covers the building blocks and workflows for using this framework effectively.
