What is the best way to get started with Swift Testing?

To get started with Swift Testing, you can follow these steps:

1. Add a Test Bundle Target:

   • In Xcode, choose File > New > Target, then search for Unit Testing Bundle in the test section. Swift Testing is the default choice for this template in Xcode 16. Choose a name for your new target and click finish.

2. Write Your First Test:

   • Add a function with a @Test attribute to your test suite. You can provide a friendly title and use macros like #expect to evaluate the result of any Swift expression, making it easy to write complex checks.

3. Organize Your Tests:

   • Use tags to organize and filter your tests. You can selectively run tests across your test suite, like tests that use a certain module or that run on a specific device. Parameterize tests to reuse the same logic over a sequence of values.

4. Run Tests:

   • You can run tests directly from Xcode or from the command line using swift test. The console will show pass and fail results with detailed failure messages.

5. Explore More Features:

   • Swift Testing supports concurrency, allowing tests to run safely in parallel. It is integrated into major tools and IDEs in the Swift ecosystem, including Swift Package Manager, Xcode, and Visual Studio Code.
