By PulseAugur Editorial · [1 sources] ·

Depop successfully migrated over 10,000 unit tests from XCTest to Swift Testing. The company utilized AI not as a direct code converter, but as a high-level migration harness. This approach involved deterministic tools to manage the end-to-end migration process, ensuring careful review of AI-driven conversions due to their semantic and non-deterministic nature. AI

IMPACT Demonstrates AI's utility in automating and managing complex software migration tasks, potentially improving developer efficiency.

    From XCTest to Swift Testing: migrating 10,000 unit tests at Depop: “AI-based conversions are semantic and non-deterministic, which means every change has to be carefully reviewed to ensure they don’t change tests in subtle ways. Instead of using AI as a low-level code converter,…
