[GSoC 2025] Improved console output for Swift Testing

Hello everyone,

My name is Ying-Chen Lin, and I am currently majoring in Computer Science. I have developed a few iOS apps using Swift and have participated in the Swift Student Challenge. Through these experiences, I have become quite familiar with writing Swift code in both Xcode and VSCode, and my primary development environment is macOS.

I really love the Swift programming language, which is why I’m eager to participate in GSoC 2025 with Swift. In particular, I’m interested in the project "Improved console output for Swift Testing"

I have read the project description and expected outcome. Also, I have already forked the repository, cloned it to my computer, and successfully built and tested it in both Xcode and the command line. While reading the project description and codebase, I came up with a few questions:

  1. The description mentions: “If time allows, implement several alternatives and present them to the community (and the Testing Workgroup) for consideration.“ Should I include all the possible alternatives I have considered in my proposal? Also, is it better to implement a demo as part of my proposal to explain my idea more clearly?

  2. Are there any issues or features that I could start working on to get myself more familiar with the codebase and contribute to swift-testing?

  3. The description also mentions: “Add a new component which receives events from the testing library and decides how to reflect them in console output.“ However, I noticed that files such as Event.ConsoleOutputRecorder and Event.HumanReadableOutputRecorder already seem to do the same thing. How does this new component differ from these existing files? Or is the goal to build on top of these existing files rather than creating a new component?

@smontgomery I would love to hear your thoughts. I would also appreciate any insights and feedback from the community. Thank you!
