What advantage does swift testing have over xctest

Swift testing offers several advantages over XCTest:

1. Expressive APIs: Swift testing has expressive APIs that make it simple to write tests. It uses macros like expect and require instead of many specialized functions, allowing you to pass in ordinary expressions and language operators to evaluate results (Platforms State of the Union, Meet Swift Testing).

2. Cross-Platform: Swift testing is cross-platform, meaning you can use it to write tests for a variety of platforms and domains, including all Apple operating systems, Linux, and Windows. This ensures better functional parity and consistent behavior across platforms (Platforms State of the Union, Meet Swift Testing).

3. Concurrency Support: Swift testing takes full advantage of Swift's concurrency model, running tests safely in parallel. This is different from XCTest, which does not natively support Swift concurrency (Platforms State of the Union, Meet Swift Testing).

4. Simplified Assertions: Instead of using many functions beginning with XCTAssert, Swift testing uses just two basic macros, expect and require, making it easier to write and understand tests (Meet Swift Testing).

5. Flexible Tagging System: Swift testing includes a flexible tagging system to help organize tests and test plans. You can selectively run tests across your test suite based on tags, which is not a feature in XCTest (Platforms State of the Union).

6. Open Source: Swift testing is developed as an open-source package, allowing for community involvement and continuous improvement (Platforms State of the Union, Meet Swift Testing).

7. Integration with Major Tools: Swift testing is integrated into major tools and IDEs in the Swift ecosystem, including Xcode 16 and Visual Studio Code, providing a seamless development experience (Meet Swift Testing).
