To use Swift Testing, you can start by adding a test attribute to your function to declare a test. You can provide a custom display name as an argument to the test attribute, which helps make it easier to understand what the test is doing. Use the expect macro to verify that the results meet your expectations, allowing you to write both simple and complex Swift expressions.
Swift Testing is designed to be expressive and easy to learn, with cross-platform support. It includes features like a flexible tagging system to organize and filter your tests, and you can parameterize tests to reuse them across different inputs. Swift Testing is integrated into major tools like Xcode 16 and Visual Studio Code, and it supports parallel testing to improve performance.
For more detailed information, you can refer to the sessions "Meet Swift Testing" and "Go further with Swift Testing" from WWDC 2024. These sessions cover the building blocks of Swift Testing, common workflows, and how it relates to XCTest.
If you want to dive deeper into Swift Testing, you can start with the Meet Swift Testing session, which provides an overview of the core concepts and workflows.
Platforms State of the Union
Discover the newest advancements on Apple platforms.
Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
